TL;DR: Isixhumi esingangeni manzi se-IP55 sivimba uthuli kanye namajethi amanzi anomfutho ophansi, okwenza kube yisilinganiso esincane kakhulu esisebenzayo sezindawo zokuvala zikagesi zangaphandle eziveziwe. Izixhumi zentambo ye-M12 (IEC 61076-2-101) ziyisinqumo esivelele sokuxhumeka kwesignali yangaphandle kanye namandla ngoba intambo yazo yokuxhuma engu-12 mm, ehambisana nesivalo se-O-ring, inikeza ukucindezela kokuhlangana okuqhubekayo. Izindawo eziningi zokufaka zangaphandle azidingi i-IP67. I-IP55 ishibhile, kulula ukuyinakekela, futhi yanele imvula, uthuli, kanye nokuwa ngezikhathi ezithile. Ifomethi ye-M12 inikeza izinhlobo zokubhala ikhodi (A, B, D, X) ezivimbela ukungalingani. Uma indawo yakho yokuvala ibhekene nezimo zemvula eziqondile noma ingozi yokucwiliswa, khuphukela ku-IP65 noma i-IP67. Ngaphandle kwalokho, isixhumi se-IP55 M12 esakhiwe kahle esinezindlu zethusi ezimbozwe nge-nickel kanye ne-silicone O-ring sizohlala iminyaka emihlanu kuya kweyisishiyagalombili ngaphandle.

Isixhumi esingangeni manzi esinesilinganiso se-IP55 asisona isixhumi esiqinile kakhulu emakethe. Asikwazi ukucwiliswa emanzini. Ngeke sisinde ekushiseni okucindezelekile lapho siseduze. Kodwa-ke yisilinganiso esisodwa esivame kakhulu esichazwe ezindaweni zikagesi zangaphandle, amabhokisi okuxhumanisa, ama-LED driver, kanye namakhabethe e-telemetry emhlabeni jikelele. Kungani? Ngoba iningi lama-elekthronikhi angaphandle alikaze licwiliswe emanzini. Lina, lithululwe uthuli, futhi ngezinye izikhathi lifakwe ngamapayipi yiqembu lokulungisa. I-IP55 iphatha lokho kanye.

Igama elithi "IP" ku-IP55 limelela ukuvikelwa kokungena, elibhalwe ngaphansi kwe- I-IEC 60529. Inombolo yokuqala, u-5, isho ukuthi indawo ebiyelwe ivikelwe uthuli — ukungena okulinganiselwe kuvunyelwe, kodwa akwanele ukuphazamisa ukusebenza. Inombolo yesibili, u-5, isho ukuthi imelana namajethi amanzi anomfutho ophansi avela ku-nozzle engu-6.3 mm ngamalitha angu-12.5 ngomzuzu imizuzu emithathu. Lokho akulona i-splash. Leyo ijethi eqondisiwe. Uma indawo ebiyelwe yakho ihlala ngaphansi kophahla, uphahla, noma imane ivezwe emvuleni eqhutshwa umoya, i-IP55 iyindawo esetshenziswa ochwepheshe bakagesi kanye nabacacisi abaphambili.

Izixhumi zentambo ze-M12 zibusa kulesi sigaba ngoba zincane, zijwayelekile, futhi zithembekile ngokwemishini. Intambo yokuxhuma engu-12 mm, echazwe ku I-IEC 61076-2-101, yasungulwa nguLumberg ngo-1985 futhi kamuva yamukelwa yi-IEC ngo-2003. Yaba yi-interface ezenzakalelayo yezinzwa zezimboni, ama-actuator, kanye ne-I/O esatshalaliswayo. Uma ubona ikhabhinethi yokulawula yangaphandle enesixhumanisi esincane esiyindilinga singena kuphaneli eseceleni, amathuba ukuthi yi-M12. Intambo ngokwayo akuyona uphawu. Uphawu luyindandatho ye-O ecindezelwe phakathi kwepulaki nesitsha njengoba intambo iqina. Uma kwenziwa kahle, lokho kucindezela kudala isithiyo se-IP55 — ngokuvamile i-IP65 noma i-IP67 —.

Kodwa indaba yangempela akuyona indinganiso. Indaba yangempela yilokho okwenzekayo uma uphambukile.

Ingozi Yangempela Okungekho Okhuluma Ngayo

Ukwehluleka okuningi kwezixhumi zangaphandle akukubi kakhulu. Kuhamba kancane. Amanzi angena nge-O-ring eyonakele ezinyangeni eziyisithupha. Ukujiya kwakha ngaphakathi kwegobolondo lesixhumi. Oxhumana nabo bayaqina. Ukumelana kuyakhuphuka. Ekugcineni isignali iyawa, noma i-breaker iyawa, bese iqembu lokulungisa lishayela amahora amabili liya ekhabhinethini elikude ukuze lithole isixhumi esingu-$4 sibhubhise isilawuli esingu-$2,000.

Ngibone le ndlela iphindaphinda kuzo zonke izimboni. Ipulazi lelanga eNevada lisebenzisa izixhumi ze-IP55 emabhokisini alo okuhlanganisa. Uthuli lwasehlane lulungile ngokwanele ukuthi ludlule ezixhumi zamandla ze-M12 ezivalwe kabi. Eminyakeni emibili edlule, ukumelana kokuthintana nezixhumi zamandla ze-M12 kukhuphuka ngokwanele ukukhiqiza ukushisa. Ukushisa kusheshisa ukuwohloka kwe-O-ring. Umjikelezo uzondla ngokwawo. Ekufakweni kogu eFlorida, inkungu kasawoti yenza into efanayo ngokushesha. Isixhumi sasiyi-IP55, kodwa izinto zokwakha zaziyi-alloy ye-zinc ejwayelekile ngaphandle kwe-nickel plating. Ukugqwala kudla intambo. Umfakisi akasakwazi ukuqinisa isixhumi ku-torque ecacisiwe. Isivalo siyahluleka.

Lokhu kwehluleka akubangelwa ukuthi i-IP55 "ibuthakathaka kakhulu." Kubangelwa ukuthi i-IP55 isetshenziswe ezintweni ezingalungile, ukufakwa okungalungile, noma ishejuli yokulungisa engalungile. Indinganiso ichaza izimo zokuhlola. Ayiqinisekisi ukusebenza kwensimu. Lowo ngumsebenzi wakho.

Inkinga iwukuthi izindleko azikho ezibekiwe. Umphathi wephrojekthi uthenga izixhumi ze-IP55 ngoba ziyingxenye yentengo yamayunithi e-IP67. Ishidi lokuthenga libukeka lihlanzekile. Ngemva kweminyaka emithathu, izimangalo zewaranti ziyaqala. Izindleko eziphelele zobunikazi ziyashintsha kancane. Okwakubonakala sengathi ukonga kwaba yisibopho. Ukuma kwami: uma ufaka ngaphandle futhi ungakwazi ukuthinta izixhumi iminyaka emithathu, ungayithengi iyunithi ye-IP55 eshibhile kakhulu. Thenga leyo enezinto ze-O-ring ezinhle kakhulu kanye ne-nickel plating ejiyile kakhulu. Ngeke uzisole.

Okushiwo Yi-IP55 Empeleni

I-IP55 iyisithembiso esithile, akuyona into engacacile yokuthi "iphikisana namanzi." Ngokusho kwe-IEC 60529, ukuhlolwa kothuli (inombolo yokuqala 5) kusebenzisa igumbi le-talc eliyimpuphu elinokukhishwa kwe-vacuum. Isixhumi sihlolwa kuze kube amahora ayisishiyagalombili. Kuvunyelwe ukungena kothuli okulinganiselwe, kodwa akumelwe kuphazamise ukusebenza noma ukuphepha. Ukuhlolwa kwamanzi (inombolo yesibili 5) kufafaza amanzi avela ku-nozzle engu-6.3 mm ngamalitha angu-12.5 ngomzuzu kusuka kunoma iyiphi indlela imizuzu emithathu. Ibanga lokuhlola licishe libe amamitha amathathu. Isixhumi akumele sivumele amanzi ngobuningi obuphazamisa ukusebenza.

Nansi imininingwane ebalulekile: ukuhlolwa kwe-IP55 kucabanga ukuthi isixhumi sisesimweni saso sokusebenza esijwayelekile. Uma indawo yakho ebiyelwe ifakwe ibheke phansi, noma uma isixhumi sibheke phezulu, amanzi angahlangana ngezindlela ezingazange zilindelwe. Amandla adonsela phansi awayona ingxenye yenqubo yokuhlola. Ngibone izixhumi ze-M12 zifakwe isitsha sibheke phezulu ngqo, siqoqa amanzi emgodini onentambo. Ngisho namayunithi e-IP67 azobhekana nalokho.

Manje qhathanisa i-IP55 nomakhelwane bayo. I-IP54 ivikela emanzini agelezayo, hhayi amajethi. I-IP65 ayivali uthuli futhi ivikelwe yijethi. I-IP67 yengeza ukucwiliswa kwesikhashana. Igebe eliphakathi kwe-IP55 ne-IP65 lincane kunegebe eliphakathi kwe-IP55 ne-IP54. I-IP55 iyisilinganiso sokuqala lapho amanzi ephoqwa khona ngokuqinile endaweni ebiyelwe, hhayi nje ukuvunyelwa ukuba awele kuyo. Ezindaweni ezibiyelwe zangaphandle ngaphansi kwama-eves noma ezimweni zezulu ezimaphakathi, i-IP55 ivame ukuba yindawo enhle. Ezindaweni ezisogwini, ezishisayo, noma ezinomfutho ophezulu, i-IP65 iyindawo ephephile.

Okufanayo eNyakatho Melika yi-NEMA 3 noma i-3R, okucishe kuhambisane ne-IP55 ngaphansi kwe- CHA 250 ejwayelekile. Kodwa-ke, izilinganiso ze-NEMA zifaka phakathi ukuhlolwa okwengeziwe kokwakheka kweqhwa, ukugqwala, kanye nokugoba kwemisele yangaphandle okungafinyelelwa yi-IEC 60529. Lezi zinhlelo ezimbili azishintshisani. Uma uthengisa eNyakatho Melika, udinga ukufakwa ohlwini lwe-NEMA. Uma uthengisa eYurophu, i-IEC 60529 ingumthetho. Abakhiqizi abaningi bomhlaba wonke manje baqinisekisa kokubili ukuze bagweme ukungqubuzana kwemakethe.

Ingxoxo ye-M12: Kungani Yaba Yiyona Ezenzakalelayo

Isixhumi se-M12 akuyona yodwa ifomethi eyindilinga engangeni manzi. I-M8 incane kodwa inqunyelwe kumandla aphansi. I-M16 ne-M23 ziphatha amandla amaningi kodwa zidinga isikhala esikhulu sephaneli futhi zibiza kakhulu. I-M12, enobubanzi bentambo engu-12 mm, ihlala phakathi. Iphethe amandla anele ezinzwa kanye nama-actuator amancane (kufika ku-16A kumandla ahlukahlukene). Incane ngokwanele ukungena emgodini wephaneli ongu-16 mm. Ishibhile ngokwanele ukuyifaka esikhundleni ngaphandle kwempikiswano nge-oda lokuthenga.

Ubuhlakani bangempela be-M12 uhlelo lokubhala ikhodi. Izixhumi ezinekhodi ye-A ziphethe izinzwa kanye namandla e-DC. Ikhodi ye-B ingeyeProfibus. Ikhodi ye-D iphatha i-Ethernet ye-100 Mbps. Ikhodi ye-X isunduzela ku-10 Gbps. Amakhodi e-K, L, S, kanye ne-T aphatha amandla e-AC afinyelela ku-630V. Lokhu kufakwa kokhiye ngokomzimba kuvimbela ukungasebenzi kahle. Awukwazi ukuxhuma ngephutha ikhebula le-Ethernet esitsheni samandla se-230V. Ezindaweni zangaphandle, lapho ochwepheshe besebenza khona ebusuku, emvuleni, nangaphansi kwengcindezi yesikhathi, lokhu akuyona into elula. Kuyisici sokuphepha.

Indlela yokusebenza kwentambo ngokwayo iqondile. Ipulaki yesilisa inentambo yangaphandle engu-M12 x 1.0. I-receptacle yesifazane ine-coupling nut yokuhlangana. Njengoba i-nut iqina, ubuso bangaphambili be-plug bucindezela i-O-ring ehlezi emseleni we-receptacle. Intambo inikeza ukugcinwa komshini kanye nokumelana nokudlidliza. I-O-ring inikeza ukuvala. Ikhwalithi yokuvala incike ezintweni ezintathu: Izinto ze-O-ring, iphesenti lokucindezela, kanye nokuphela kobuso.

Ama-silicone O-rings asetshenziswa ngokuzenzakalelayo ukusetshenziswa kwangaphandle okuvamile. Aphatha u--40°C kuya ku-+200°C, amelana ne-UV, futhi ahlala eguquguqukayo. I-Fluoroelastomer (FKM/Viton) iyadingeka ukuze kutholakale uphethiloli, uwoyela, noma amazinga okushisa aphezulu ahlala isikhathi eside. I-EPDM iphatha umusi kodwa ayinamandla uma iqhathaniswa nophethiloli. I-NBR ishibhile kodwa yonakala elangeni. Ezindaweni zikagesi zangaphandle, i-silicone iyindlela ephephile. Kwabasolwandle noma abasogwini lolwandle, i-FKM iyindlela ephephile.

Izinto zokwakha izindlu zibalulekile. I-nickel-plated yethusi inikeza ukumelana okuhle kakhulu nokugqwala kanye nokuqina kwentambo. I-alloy ye-zinc ene-nickel plated ishibhile futhi iyamukeleka ezindaweni eziningi zezimboni. I-PA66 egcwele ingilazi iyindlela engabizi kakhulu yezinhlelo zokusebenza ezingabalulekile. Ilula futhi iyabunjwa kodwa ingaqhekeka ngaphansi kwe-torque ephezulu. Insimbi engagqwali 316 iyindinganiso yegolide yasolwandle. Ibiza ngokuphindwe kathathu kuya kahlanu kune-nickel-plated yethusi.

Oxhumana nabo ngokuvamile bangama-phosphor bronze kanye ne-gold plate phezu kwe-nickel. Ubukhulu begolide busukela kuma-micron angu-0.1 kuya ku-1.0. I-thick plate isinda imijikelezo eminingi yokuhlangana. Isixhumi esijwayelekile se-M12 silinganiselwe imijikelezo yokuhlangana engu-100 kuya ku-500. Izinhlobo eziphezulu zifinyelela ku-5,000 noma ngaphezulu. Ukufakwa kwangaphandle okuhleliwe okuthintwa kanye ngonyaka ngesikhathi sokulungiswa, imijikelezo engu-100 yanele. Emishinini yokuhlola noma emishinini ephathekayo, u-500 ubuncane.

Uma i-IP55 Yanele, Futhi Uma Inganele

I-IP55 yanele uma indawo ebiyelwe iqonde phezulu, imvula ingumthombo wamanzi oyinhloko, futhi uthuli luyizinto ezivamile zasemadolobheni noma zezimboni. Izibani zasemgwaqweni, amakhabethe okulawula ithrafikhi, amayunithi e-telemetry akude, namabhokisi okuhlanganisa amandla elanga konke kuwela kulesi sigaba. Isixhumi asingaphansi kwamanzi. Asihlanzwa ngomusi. Siniselwa imvula futhi ngezinye izikhathi siyasulwa.

I-IP55 ayanele uma indawo ebiyelwe iseduze nomhlabathi ezindaweni ezivame ukukhukhulwa yizikhukhula, lapho ukuhlanza ngomfutho ophezulu kuyinto evamile (ukucubungula ukudla, ezolimo), noma lapho isixhumi singafakwanga ezimweni ezimanzi. Njengoba ochwepheshe bezixhumi bephawula, isilinganiso se-IP sohlelo lokuxhuma sivame ukubhekisela esimweni sokuhlangana. Uma isixhumi sisusiwe, isitsha sehlela ku-IP55 noma ngaphansi ngaphandle kokuthi kufakwe isivalo sothuli esivaliwe. Yingakho izixhumi zokushaja ze-EV kumele zigcine i-IP55 ngisho nalapho isibambo sisusiwe emotweni. Ukuhlolwa kunzima, futhi intengo iyakubonisa lokho.

Iseluleko sami sokuthenga: qala nge-IP55 yesikhala esingu-80%. Sebenzisa i-IP65 ezindaweni zasehlane ezisogwini, ezishisayo, noma ezinothuli oluningi. Sebenzisa i-IP67 kuphela uma ukucwiliswa kwesikhashana kuyingozi yangempela - amakamelo angaphansi komhlaba, imigodi, amadekhi olwandle. I-IP68 iwukucwiliswa okuqhubekayo futhi ingaphezu kwamandla angu-95% wezindawo zikagesi zangaphandle. Isinyathelo ngasinye siphinda kabili izindleko zokuxhuma. Izindleko zokuvala nazo ziyakhuphuka ngoba izinto ze-gasket, indlela yokukhiya, kanye nokubekezelelana kokukhiqiza kuba nzima.

Kukhona ugibe lokuthenga engilubona ngokuphindaphindiwe: ukuthenga izixhumi ze-IP67 nokuzifaka endaweni evalekile ye-IP55. Isixhumanisi esibuthakathaka yileyo ndawo evalekile. Amanzi angena nge-gasket yomnyango, ageleze phansi, bese ecwilisa isixhumi. Isixhumi se-IP67 siyasinda. Indawo evalekile ayiphumeleli. Uhlelo luyahluleka. Qondanisa isixhumi nendawo evalekile. Qondanisa indawo evalekile nendawo ezungezile. Ungagxili kakhulu engxenyeni eyodwa bese ucindezela okusele.

Icala Elivela Ensimini

Ngo-2023, iphrojekthi yokukhanyisa i-LED yezimboni eTexas yasebenzisa izixhumi ze-IP55 M12 kumakhabethe okulawula angaphandle angu-300. Imininingwane yayicacile: IP55, i-A-coded, i-4-pin, indlu ye-nickel eboshwe ngethusi, i-silicone O-ring. Umthengisi waletha imininingwane. Ukufakwa kwakuhlanzekile. Phakathi nezinyanga eziyisishiyagalombili, imibiko yokwehluleka yaqala ukufika ivela emaphethelweni asentshonalanga yesiza.

Uphenyo lwembule imbangela elula: amakhabethe asentshonalanga ayebhekene nomoya ovamile, owawuthwala uthuli lwe-caliche oluncane oluvela endaweni yokwakha eseduze. Ukuhlolwa kothuli lwe-IP55 kusebenzisa i-talc. Uthuli lwe-Caliche lubukhali, lunolaka kakhulu, futhi luqukethe i-calcium carbonate. Uthuli lwangena endlini yesixhumi ngobuningi obungalindelekile. Aluzange lubangele ukwehluleka okusheshayo. Kunalokho, lwaqoqana eduze komsele we-O-ring, lwakha unamathisela wokugaya. Isikhathi ngasinye lapho ukulungiswa kunqamula ikhebula lokuhlola, uthuli lwalushaya ubuso be-O-ring. Ngemva kokunqamula okuyisithupha, uphawu lwaluba sengozini. Amanzi angena ngesikhathi semvula elandelayo. Oxhumana nabo bagqwala. Izibani zacima.

Ukulungiswa kwakungekona ukuthuthukela ku-IP67. Kwakuwukushintshela kuzixhumi eziqinile uthuli ze-IP65 ezinesilinganiso sokucindezela i-O-ring esiqinile kancane bese kungezwa isivalo sothuli kunoma yisiphi isitsha esingakakhiwa. Ukwenyuka kwezindleko kwakungu-$0.40 ngesixhumi ngasinye. Izinga lokuhluleka lehle laya ku-zero. Isifundo: I-IP55 iphatha ukuhlolwa. Ayiphathi zonke izimo zensimu. Ulwazi lwendawo lubaluleke kakhulu kuneshidi lemininingwane.

Ukuthenga Ngaphandle Kokuzisola

Uma uthola izixhumi eziyindilinga ezingangeni manzi zezindawo zokuvala zangaphandle, buza umthengisi imibuzo emihlanu. Okokuqala: siyini isilinganiso se-IP esiqondile, futhi ingabe siqinisekiswe ilebhu yangaphandle noma esizibizayo? Okwesibili: siyini i-O-ring material, futhi siyini izinga lokushisa? Okwesithathu: siyini isilinganiso somjikelezo wokuhlangana, futhi ingabe ubukhulu be-contact plating buhlangabezana nesimiso sakho sokulungisa? Okwesine: ingabe izinto zokuhlala ziyahambisana nendawo yakho — i-zinc alloy yezimboni ezomile, i-brass nickel yangaphandle evamile, insimbi engagqwali yasolwandle? Okwesihlanu: siyini usayizi wembobo yephaneli kanye nobude bokubandakanya intambo, futhi ingabe kuyahambisana nomklamo wakho we-enclosure?

Ungazamukeli izimpendulo ezingacacile. "Isilinganiso se-IP55" ngaphandle kwesitifiketi sokuhlola kumane kuyisicelo nje. Umhlinzeki othembekile uzonikeza umbiko wokuhlolwa we-IEC 60529, isitifiketi sokuthobela i-RoHS, kanye neshidi ledatha elibalulekile. Uma bengakwazi, qhubeka ubheka. Izindleko zesixhumi esihlulekile ekhabhinethini elikude azilona nje intengo yesixhumi. Yizisebenzi, ukuhamba, isikhathi sokungasebenzi, kanye nesikhalazo samakhasimende.

Imigqa yemikhiqizo ehlobene yabakhi bamaphaneli ifaka phakathi amabhlogo we-terminal kanye nezinhlelo zokuphatha izintambo ezenza kube lula ukuxhuma izintambo. Isibonelo, izintambo Ibhulokhi yesiteshi sokufaka isitimela se-PCT-211 DIN kunciphisa isikhathi sokuxhuma ngokuqeda ukuhlolwa kwe-torque yesikulufo. Ukuxhumeka kwe-spring-clamp kugcina ingcindezi yokuxhumana ngokudlidliza kanye nokujikeleza kwezinga lokushisa, okubaluleke kakhulu kumakhabhinethi angaphandle lapho ukwanda kokushisa kwenzeka khona nsuku zonke. Phequlula konke ikhathalogi yesixhumi kanye nebhulokhi yesiphetho izingxenye ezihambisanayo zokuvala.

Into yokugcina nge-torque. Intambo ye-M12 kufanele iqiniswe ngokwezidingo zomenzi, ngokuvamile kusuka ku-0.8 kuya ku-1.2 Nm. I-over-torque icindezela i-O-ring ngaphezu komkhawulo wayo wokunwebeka. Iyawohloka unomphela futhi ayibe isalulama. I-Under-torque ishiya izikhala. Sebenzisa i-torque wrench. Ungaqageli. Umehluko phakathi kokuxhumeka okuqinile nokuxhumeka okuvaliwe uyalinganiswa, awuqondakali.

Imibuzo Evame Ukubuzwa

Ingabe izixhumi ze-IP55 zingasetshenziswa emvuleni eqondile?

Yebo, i-IP55 ilinganiselwe amajethi amanzi anomfutho ophansi avela kunoma iyiphi indlela, okuhlanganisa nemvula eqhutshwa ngumoya. Kodwa-ke, uma isixhumi sifakwe ngokuvundlile noma sibheke phezulu, amanzi angahlangana emgodini wentambo. Faka ngokuqondile noma nge-drip loop noma nini lapho kungenzeka.

Uyini umehluko phakathi kwe-M12 A-code kanye ne-D-code?

Ikhodi ye-A ingeyezinzwa kanye namandla e-DC, ngokuvamile amaphini ama-2 kuya kwangu-8. Ikhodi ye-D ingeye-100 Mbps Ethernet, njalo amaphini ama-4. Ukufaka ukhiye ngokomzimba kuvimbela ukuxhumanisa ipulaki yekhodi ye-A ne-receptacle yekhodi ye-D. Khetha ikhodi ye-A yesiginali evamile kanye namandla. Khetha ikhodi ye-D ye-Ethernet yezimboni.

Ingabe i-IP55 yanele ezindaweni ezisogwini?

I-IP55 iphatha imvula nothuli, kodwa inkungu kasawoti iyinkinga ehlukile. Usawoti usheshisa ukugqwala entanjeni yendlu kanye ne-contact plate. Ekufakweni kogu, sebenzisa i-IP65 okungenani bese ucacisa izindlu zensimbi ezimbozwe nge-nickel noma zensimbi engagqwali. Cabanga ngama-O-ring e-FKM uma kukhona ukuchayeka kuphethiloli.

Isixhumi se-IP55 M12 sihlala isikhathi esingakanani ngaphandle?

Ngezindandatho ze-silicone O kanye nezindlu zethusi ezimbozwe nge-nickel, iminyaka emihlanu kuya kweyisishiyagalombili ivamile ezindaweni ezinesimo sezulu esifudumele. Ezindaweni ezinzima — i-UV ephezulu, amazinga okushisa aphezulu, ukuchayeka kumakhemikhali — isikhathi sokuphila siyehla siye eminyakeni emibili kuya kwemine. Ukuhlolwa konyaka kanye nokufakwa esikhundleni kwendandatho ye-O kuyindlela engcono kakhulu yokulungisa.

Ngingakwazi yini ukuthuthukisa isixhumi se-IP55 sibe yi-IP67 ngokushintsha i-O-ring?

Cha. Isilinganiso se-IP siyimpahla esezingeni lesistimu. Umklamo wendlu, ubude bokuxhumana kwentambo, uphawu lwephaneli, kanye ne-cable gland konke kunegalelo. Awukwazi ukuthola i-IP67 ngokushintsha i-O-ring kusixhumi se-IP55. Uma udinga i-IP67, thenga isixhumi esilinganiselwe i-IP67 esenzelwe sona.

Yiluphi ububanzi bekhebula olufanela i-M12 cable gland?

Ama-gland ekhebula ajwayelekile e-M12 amukela ububanzi bekhebula obungu-3.5 mm kuya ku-6.0 mm. Hlola ishidi ledatha le-gland ukuze uthole ububanzi obuqondile. Ikhebula elincane kakhulu ngeke livale. Ikhebula elikhulu kakhulu lizocindezela imicu ye-gland. Zombili lezi zimo azivumeli isilinganiso se-IP ngokoqobo.

Izixhumi eziyindilinga ezingangeni manzi ezinesilinganiso se-IP55 azijabulisi. Azizona izinto eziyinhloko. Ziyizinto ezisebenza ngokuthula zengqalasizinda kagesi yangaphandle. Khetha izinto ezifanele, uzifake ngokucophelela, uhlole minyaka yonke, futhi zizohlala isikhathi eside kunemishini ezixhumayo. Khetha kabi, futhi ingxenye engu-$4 iba yimbangela yokuthi uhlelo lwe-$50,000 luyeke ukusebenza. Isinqumo silula. Isiyalo yisona esihlukanisa ukufakwa okuthembekile nezifundo ezibizayo.
