I-Magnetic proximity switch iwuhlobo lokushintshwa kwe-proximity switch, okungenye yezinhlobo eziningi emndenini wezinzwa. Yenziwe ngesimiso sokusebenza kwe-electromagnetic kanye nobuchwepheshe obuthuthukisiwe, futhi iwuhlobo lwenzwa yendawo. Ingashintsha inani elingelona likagesi noma inani likazibuthe libe isignali kagesi efiswayo ngokushintsha ubuhlobo bendawo phakathi kwenzwa nento, ukuze kuzuzwe injongo yokulawula noma yokulinganisa.
Iswishi ye-magnetic proximity ingafinyelela ibanga eliphezulu lokutholwa ngevolumu encane yokushintsha. Ingakwazi ukubona izinto kazibuthe (imvamisa omazibuthe baphakade), bese ikhiqiza ukuphuma kwesiginali ye-trigger switch. Njengoba indawo kazibuthe ingadlula ezintweni eziningi ezingezona kazibuthe, inqubo yokucupha ayidingi ukuthi into eqondiwe ukuthi isondele ngokuqondile endaweni yokungeniswa yeswishi eseduze kazibuthe. Esikhundleni salokho, amandla kazibuthe adluliselwa ebangeni elide nge-conductor kazibuthe (njengensimbi). Isibonelo, amasiginali angadluliswa kuswishi ye-magnetic proximity ngokusebenzisa izinga lokushisa eliphezulu ukuze kukhiqizwe isignali yesenzo esicuphayo.
Umgomo wokusebenza wokushintshwa kwe-magnetic proximity switch:
Iswishi ye-magnetic proximity ingafinyelela ibanga eliphezulu lokutholwa ngevolumu encane yokushintsha. Ingakwazi ukubona izinto kazibuthe (imvamisa omazibuthe baphakade), bese ikhiqiza ukuphuma kwesiginali ye-trigger switch. Njengoba indawo kazibuthe ingadlula ezintweni eziningi ezingezona zikazibuthe, inqubo yokucupha ayidingi ukuthi into eqondiwe ukuthi isondele ngokuqondile endaweni yeswishi eseduze kazibuthe, kodwa idlulisela indawo kazibuthe nge-conductor kazibuthe (njengensimbi). ) ukuya ebangeni elide. Isibonelo, isignali ingadluliselwa kusishintshi sokusondela kazibuthe ngokusebenzisa izinga lokushisa eliphezulu ukuze kukhiqizwe isignali yesenzo esicuphayo.
Isebenza njenge-inductive proximity switch, equkethe i-oscillator ye-LC, i-trigger yesiginali, kanye ne-switching amplifier, kanye ne-amorphous, i-high-penetrate glass metal core yensimbi ethambile enozibuthe ebangela ukulahlekelwa kwamanje kwe-eddy futhi inciphise umjikelezo we-oscillating. Uma ibekwe endaweni kazibuthe (isibonelo, eduze kukazibuthe unomphela), umgogodla uklanyelwe ukunciphisa imvamisa ye-oscillation circuit. Ngalesi sikhathi, ukulahlekelwa kwamanje kwe-eddy okuthinta ukuncishiswa kwe-oscillation circuit kuzoncishiswa, futhi isifunda se-oscillation ngeke sincishiswe. Ngakho-ke, amandla adliwe yi-switch magnetic proximity akhuphuka ngenxa yokusondela kukazibuthe unomphela, futhi i-trigger yesignali icushiwe ukuze ikhiqize isignali ephumayo. Inezinhlobonhlobo zezinhlelo zokusebenza, njengokuthi: kungaba ngesitsha sepulasitiki noma ipayipi ukuze kutholwe into; Ukutholwa kwento endaweni yokushisa ephezulu; Uhlelo lokuxazulula izinto; Sebenzisa uzibuthe ukukhomba amakhodi, njll.
