1. Mekanikal ya limit switch

Kaslakan, sayan klase na switch et uusaren pian limitaan so posisyon o stroke na mekanikal ya galaw, pian say onkukurang a makina et automatikon ontunda, makabaliktad so galaw, manguman-uman so kapeles na galaw odino automatikon manpapawil so galaw unong ed sakey a posisyon odino stroke. Saya so walaan na operating head, sakey a contact system tan sakey a housing. Inapag ed direct-action (button), rolling (rotary), micro-action tan kombinasyon.

Direct-acting limit switch: say prinsipyo na kiwas et mipara ed samay buton, say pandumaan et say sakey et manual, tan say sananey et nababanggaan na bumper na onkukurang a parte. No say impact block ed paway ya onkukurang a parte et manpindot ed buton pian onkiwas so kontak, no ontaynan so onkukurang a parte, say kontak et automatikon man-reset ed silong na kiwas na spring.

Rolling limit switch: No say stop iron (collision block) na onkukurang a makina et pindoten ed roller na limit switch, say transmission rod et onliber a kaiba so rotating shaft, kanian itulak na cam so impact block, tan no onsabi so impact block ed sakey a posisyon, itulak to so micro movement Say switch et maples ya onkikiwas. No naekal so stop iron ed roller, say return spring et mangi-reset ed travel switch. Saya et sakey a single-wheel automatic recovery limit switch. Tan say two-wheel rotary type travel switch et ag makabawi ya automatiko, tan no manmamatalek ed manggagalaw ya makina ya onkukurang ed kabaliktaran a direksion, say iron stopper et ontumba ed sananey a roller pian makabawi itan.

Say micro switch et sakey a snap switch ya papaandaren na pressure. Say prinsipyo na pantratrabaho to et say paway a mekanikal a puersa so onkikiwas ed action reed panamegley na transmission element (pindoten so pin, buton, lever, roller, tan arum ni), tan kayari na pakatipon na enerhiya ed kritikal a punto, sakey a tampol ya aksion so nagawa, kanian say onkukurang a kontak ed sampot na action reed. No naekal so puersa ed transmission element, say action reed et mamawala na reverse action force, tan no say reverse stroke na transmission element et onsabi ed kritikal a punto na aksion na reed, say reverse action et nasumpal a tampol. Melag so distansya na micro switch, antikey so action stroke, melag so pressing force, tan maples so on-off. Say kapeles na kiwas na onkukurang a kontak to et anggapoy pibabali to ed kapeles na kiwas na elemento na transmisyon. Say manunan klase na micro switch et say push pin type, ya nayarin naala ed button short stroke type, button large stroke type, button extra large stroke type, roller button type, reed roller type, lever roller type, short arm type, long arm type etc.

Say mechanical valve limit switch et kaslakan ya manguusar na micro switch na passive contact, tan say switch form et nayarin naapag ed: single pole double throw SPDT, single pole single throw SPST, double pole double throw DPDT.

2. Proximity limit switch

Say proximity switch, ya tatawagen met ya non-contact travel switch, et aglabat nayarin salatan so travel switch na contact pian nasumpal so travel control tan limitasyon na proteksion, no ag ingen nausar met itan parad atagey a panagbilang, panagsukat na kapeles, panagkontrol na lebel na likido, pakadetektaan na kabaleg na parte, automatikon koneksion na saray pamaakaran na panagproseso. Lapud walaan itan na saray katangian ya ag-onkontak ed trigger, maples ya kapeles na kiwas, kiwas ed loob na nanduruman distansya na pakadetektaan, malet tan anggapoy pulso na signal, malet tan napanmatalkan a kimey, andukey a bilay, atagey ya inkasusto na panagposisyon ed paulit-ulit tan pakaadapta ed mairap iran kaliberliber na pantratrabahoan, tan arum nira, kanian saya so malaknab ya uusaren ed industriyal a produksyon a singa say panag-imprinta na makina, textil, plastik tan plastik.

Saray proximity switch et naapag unong ed prinsipyo na pantratrabaho: manunan high-frequency oscillation type, Hall type, ultrasonic type, capacitive type, differential coil type, permanent magnet type, tan arum nira. Permanent magnet type: Uusaren toy suction force na permanent magnet pian na-drive so reed switch pian makapaway na signal.

Differential coil type: Uusaren to so eddy current tan say panguman na magnetic field ya napapawala no onasingger so naimano ya bengatla, tan mankikimey ed panamegley na pandumaan na detection coil tan say comparison coil. Capacitive proximity switch: Say manunan tugyopen na capacitive oscillator tan electronic circuit. Say kapasidad to et walad sensing interface. No onasingger so sakey a bengatla, sikatoy onyurong lapud panguman na coupling capacitance value to, diad ontan et makapawala na oscillation odino ontunda so oscillation pian makagawa na output signal. mas dakel so manguuman. Hall proximity switch: Mankikimey iya diad panguman na magnetic signals ed electrical signal output, tan say output to et walay memory retention function to. Say internal magnetic sensitive device et sensitibo labat ed magnetic field ya akapeket ed sampot na sensor. No say magnetic pole S et akaarap ed proximity switch, say output na proximity switch et walay positibon lukso to, tan say output to et atagey. No say magnetic pole N et akaarap ed proximity switch, say output et abeba. sukat.

Ultrasonic proximity switch: Saya et manunan tugyopen na piezoelectric ceramic sensors, electronic devices parad pangipasabi na ultrasonic waves tan pangawat na reflected waves, tan program-controlled bridge switches parad pangi-adjust na detection range. Saya so matukoy parad pakanengneng ed saray bengatlan ag nayarin o ag nayarin diwiten. Say control function to et ag nadisturbo na saray bengatla a singa say tanol, kuryente, tan liwawa. Say detection target et nayarin sakey a bengatla ya walad solido, likido odino pulbos, basta sarag ton i-reflect iray ultrasonic waves.

High-frequency oscillation proximity switch: Saya so papakiwasen na metal, a manunan tugyopen na taloran parte: high-frequency oscillator, integrated circuit odino transistor amplifier tan output device. Say prinsipyo na pantratrabaho to et: say coil na oscillator et manggagawa na alternating magnetic field ed aktibon tapew na switch, no say metal ya bengatla et onasingger ed aktibon tapew, say eddy current ya napapawala ed loob na metal ya bengatla et mangasep ed enerhiya na oscillator, ya pansengegan na itunda na oscillator ya yegyeg. Say duaran signal na oscillation tan vibration stop na oscillator et nauman ed binary switching signals kayari na inkaporma tan inka-amplify, tan saray switching control signals so ompaway.

Say magnetic induction valve limit switch et kaslakan ya manguusar na electromagnetic induction proximity switch na passive contact, tan say switch form et nayarin naapag ed: single pole double throw SPDT, single pole single throw SPSr, balet anggapoy double pole double throw DPDT. Say magnetic induction et kaslakan ya naapag ed 2-wire ya normal ya lukas o normal ya sarado, tan say 3-wire et mipara ed single-pole double-throw SPDT, ya anggapoy normal ya lukas tan normal ya sarado.
