Thupui pawimawh tak tak:Mechanical limit hmanga tihkhawtlai a ni a; Proximity limit switch a ni

1. Mechanical hmanga tihkhawtlai theihna tur

A tlangpuiin he switch chi hi mechanical movement awmna hmun emaw stroke emaw tihtlem nan hman a ni a, chutiang chuan moving machinery chu position emaw stroke emaw a zirin automatic in a ding thei a, a reverse movement, variable speed movement emaw automatic reciprocating movement emaw a ti thei a ni. Operating head, contact system leh housing te a awm a ni. Direct-action (button), rolling (rotary), micro-action leh combination-ah te then a ni.

Direct-acting limit switch: action principle hi button nen a inang a, a danglamna chu pakhat chu manual a ni a, pakhat chu moving part bumper in a insu a ni. External moving part-a impact block chuan contact move turin button a hmet chuan, moving part a chhuah chuan spring action hnuaiah contact chu a reset nghal vek a ni.

Rolling limit switch: Moving machine stop iron (collision block) chu limit switch roller-ah press a nih chuan transmission rod chu rotating shaft nen a inher kual a, chutiang chuan cam chuan impact block chu a nawr a, impact block hian hmun engemaw zat a thlen chuan micro movement a nawr a Switch hian a thawk rang hle. Roller-a stop iron chu lakchhuah a nih chuan return spring chuan travel switch chu a reset leh ta a ni. Hei hi single-wheel automatic recovery limit switch a ni. Tin.

Micro switch chu pressure hmanga tihchak snap switch a ni. A hnathawh dan chu pawn lam mechanical force chuan action reed-ah transmission element (press pin, button, lever, roller, etc.) hmangin hna a thawk a, chu chu critical point-a energy a khawlkhawm hnuah instantaneous action a lo piang a, chutiang chuan action reed tawp lama moving contact chu point leh fixed contact chu rang takin an inzawm emaw, an inzawm lo emaw a ni. Transmission element-a force awm chu lakchhuah a nih chuan action reed chuan reverse action force a siam a, transmission element-a reverse stroke chuan reed-a action critical point a thlen chuan reverse action chu a zo nghal vek a ni. Micro switch contact distance a tlem a, action stroke a tawi a, pressing force a tlem a, on-off a rang bawk. A moving contact action speed hi transmission element action speed nen hian inzawmna a nei lo. Micro switch chi bulpui ber chu push pin type a ni a, hei hi 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 atanga lak chhuah theih a ni.

Mechanical valve limit switch hian passive contact-a micro switch a hmang tlangpui a, switch form hi hetiang hian then theih a ni: single pole double throw SPDT, single pole single throw SPST, double pole double throw DPDT.

2. Proximity limit switch a ni

Proximity switch, non-contact travel switch tia hriat bawk hian travel switch chu contact hmangin a thlak thei a, travel control kimchang leh venhimna tihtlem nan a hmang thei mai bakah, high counting, speed measurement, liquid level control, part size detection, automatic connection of processing procedures wait atan pawh hman theih a ni. A chhan chu non-contact trigger, action speed chak, detection distance hrang hrang chhunga action, stable leh pulse-free signal, hnathawh nghet leh rintlak, dam rei, repeat positioning accuracy sang tak leh hnathawhna hmun harsa tak takah pawh a insiamrem theihna, etc., chuvangin Industrial production-ah te hman a ni nasa hle a, chu chu machine tools, textiles, printing, leh plastics te hi a ni.

Proximity switch te hi hnathawh dan tur angin an inthen a: a bik takin high-frequency oscillation type, Hall type, ultrasonic type, capacitive type, differential coil type, permanent magnet type, etc. Permanent magnet type: Permanent magnet suction force hmangin reed switch chu signal output turin a khalh thin.

Differential coil type: Thil hmuhchhuah a hnaih huna eddy current leh magnetic field inthlak danglamna a hmang a, detection coil leh comparison coil inthlauhna hmangin a thawk a ni. Capacitive proximity switch: A bulpui ber chu capacitive oscillator leh electronic circuit atanga siam a ni. A capacitance hi sensing interface-ah a awm a. Thil pakhat a hnaih chuan a coupling capacitance value a inthlak avangin a oscillate ang a, chu chuan oscillation a siam ang emaw, oscillation chu a titawp ang a, output signal a siam ang. inthlak danglamna a tam tial tial. Hall proximity switch: Magnetic signal chu electrical signal output-ah a chantir a, a output hian memory retention function a nei bawk. Internal magnetic sensitive device hian sensor tawp lam hawia perpendicular magnetic field chauh a sensitive a ni. Magnetic pole S chu proximity switch lam hawi a nih chuan proximity switch output chuan positive jump a nei a, output pawh a sang hle. Magnetic pole N chu proximity switch lam hawi a nih chuan output a hniam tihna a ni. tlukpui.

Ultrasonic proximity switch: Piezoelectric ceramic sensor, ultrasonic wave thawn chhuah leh reflected wave dawng thei tur electronic device, leh detection range siamremna tur program-controlled bridge switch hmanga siam a ni ber. Thil khawih theih loh leh khawih theih loh hriat theihna atan a tha hle. A control function hi sound, electric leh light ang chi thilin a tibuai lo. Detection target chu solid, liquid emaw powder state-a thil awm a ni thei a, ultrasonic wave a reflect theih phawt chuan.

High-frequency oscillation proximity switch: Metal hmanga trigger a ni a, a bik takin hmun thum atanga siam a ni a, chungte chu high-frequency oscillator, integrated circuit emaw transistor amplifier leh output device te an ni. A hnathawh dan chu: oscillator coil hian switch active surface-ah alternating magnetic field a siam chhuak a , metal object pakhatin active surface a hnaih chuan metal object chhunga eddy current lo chhuak chuan oscillator energy chu a absorb ang a, chu chuan oscillator chu a vibrate tawh lo ang. Oscillator-a oscillation leh vibration stop signal pahnih chu an shape leh amplified hnuah binary switching signal-ah an inthlak a, switching control signal te chu output a ni.

Magnetic induction valve limit switch hian a tlangpuiin passive contact-a electromagnetic induction proximity switch a hmang a, switch form hi hetiang hian then theih a ni: single pole double throw SPDT, single pole single throw SPSr, mahse double pole double throw DPDT erawh a awm lo. Magnetic induction hi a tlangpuiin 2-wire normally open emaw normally closed emaw-ah then a ni a, 3-wire hi single-pole double-throw SPDT nen a inang a, normally open leh normally closed a awm lo.
