I-Magnetic proximity switch iwuhlobo lokushintshwa kwe-proximity switch, okungenye yezinhlobo eziningi emndenini wezinzwa.Yenziwe ngesimiso sokusebenza kwe-electromagnetic kanye nobuchwepheshe obuthuthukile, futhi iwuhlobo lwenzwa yendawo.Ingashintsha inani elingelona likagesi noma ubuningi be-electromagnetic ibe 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 ibe seduze ngqo nendawo yokungeniswa yeswishi eseduze kazibuthe, kodwa idlulisela indawo kazibuthe nge-conductor kazibuthe (njengensimbi). ) ukuya ebangeni elide.Isibonelo, isignali ingadluliselwa kusishintshi sokusondela kazibuthe ngezinga 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 isekethe ye-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 ukukhiqiza isignali yokuphumayo.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.
