Misela isantya apho into okanye umatshini uza kuhamba khona kwaye ukhethe iswitshi yomda enokuphendula ngokuchanekileyo nangokuthembekileyo ngaphakathi kwelo nqanaba lesantya. Ngokufanayo, cinga ngamandla okanye uxinzelelo oluza kudibana nalo iswitshi kwaye uqinisekise ukuba iyakwazi ukusingatha umthwalo ofunekayo.
Isitshixo soMda sePlunger esitywiniweyo
Uhlobo lwe-Actuator:
Iiswitshi ze-Limit ziza neentlobo ezahlukeneyo zee-actuators, eziziindlela ezenza unxibelelwano lomzimba nento evakalayo. Iintlobo eziqhelekileyo ze-actuator ziquka i-plunger, i-roller lever, i-whisker, i-rod lever, kunye ne-spring-loaded. Ukukhetha uhlobo lwe-actuator kuxhomekeke kwizinto ezifana nokuma, ubungakanani, kunye nokuhamba kwento eza kubonwa. Cinga ngeempawu zomzimba zento kwaye ukhethe i-actuator eya kubonelela ngonxibelelwano oluthembekileyo noluhambelanayo.
Uqwalaselo loQhagamshelwano:
Iiswitshi zomda zibonelela ngoqwalaselo olwahlukeneyo loqhagamshelwano, kuquka oonxibelelwano abaqhelekileyo abavulekileyo (NO), abaqhele ukuvalwa (NC), kunye noonxibelelwano olutshintshayo (CO). Uqwalaselo loqhagamshelwano lumisela imeko yoqhagamshelwano xa lungasebenzi kwaye lusebenza nini. Khetha uqwalaselo olufanelekileyo loqhagamshelwano ngokusekelwe kwiimfuno zesicelo sakho kunye nokuziphatha okufunwayo kwenkqubo yolawulo.
Amanqaku oMbane:
Vavanya ukulinganiswa kombane kweswitshi yomda ukuqinisekisa ukuhambelana nenkqubo yakho yombane. Cinga ngezinto ezifana ne-voltage, i-current, kunye nomthamo wokutshintsha ophezulu. Qinisekisa ukuba iswitshi inokusingatha umthwalo wombane kunye namanqanaba ombane afunekayo kwisicelo sakho. Nika ingqalelo kumthamo wokutshintsha ophezulu ukuthintela umonakalo okanye ukungaphumeleli kwangaphambili kweswitshi xa uphatha imisinga ephezulu okanye ii-voltage.
Iinketho zokuFaka kunye noQhagamshelo:
Cinga ngeendlela zokufaka kunye nokudibanisa ezikhoyo kwiswitshi yomda. Iintlobo eziqhelekileyo zokufaka ziquka i-paneli mount, i-surface mount, kunye ne-DIN rail mount. Khetha ukhetho lokufaka oluhambelana neemfuno ezithile zokufakela kunye nendawo ekhoyo. Ukongeza, cinga ngeendlela zokudibanisa, ezifana nee-screw terminals okanye ii-quick-connect terminals, kwaye ukhethe eyona ifanelekileyo kwi-wire setup yakho.
Ukhuseleko kunye neSatifikethi:
Ukuba isicelo sakho siquka imisebenzi ebalulekileyo yokhuseleko okanye ukuthotyelwa kwemigangatho ethile yoshishino, qinisekisa ukuba i-limit switch iyahlangabezana neemfuno zokhuseleko kunye nesatifikethi ezifunekayo. Khangela ii-switches eziqinisekiswe yimibutho eyaziwayo okanye ezihambelana nemigangatho yoshishino efana ne-UL (Underwriters Laboratories), i-CE (Conformité Européene), okanye i-IEC (International Electrotechnical Commission).
Ukuthembeka Nokuqina:
Ukuthembeka nokuqina zizinto ezibalulekileyo xa ukhetha iswitshi yomda. Khangela iiswitshi ezivela kubavelisi abaziwayo ngokuvelisa iimveliso ezikumgangatho ophezulu nezithembekileyo. Cinga ngobomi obulindelekileyo beswitshi kunye nazo naziphi na iimfuno zokugcinwa kwayo. Ukongeza, jonga iimpawu ezinje ngokhuseleko lokunyuka oluzakhelwe ngaphakathi, ukucoca abantu abanxibelelana nabo, okanye iindlela zokuvala ukuqinisekisa ukuthembeka kwexesha elide kunye nokunciphisa ixesha lokungasebenzi.
