Heschen Inductieve naderingsschakelaar met sensor LJ18A3-8-Z/AY detector 8mm 10-30VDC 200mA, PNP NC (normaal gesloten), 3 draden

Prodotto pessimo messo sulla scheda madre per avere uno stadio logico, lui impazzisce e lavora al contrario, sostituito con un'altro,il secondo non ha nemmeno provato a funzionare articolo pessimo, consiglio non compratelo, impossibile che due su due hanno lo stesso problema, al più presto avviero la procedura di reso.

Der Schalter macht bisher einen guten Job. Ich habe 7,99€ gezahlt. Da kann man nicht meckern.Nachtrag: Seit jetzt fast 5 Jahren im Einsatz und meldet immer noch zuverlässig, ob mein Garagentor offen ist.

He comprado este sensor para mi impresora 3D. Al montarlo se me saltó un pequeño detalle: no tiene el tornillo para regular el tope de distancia a la placa.Es por esto que es inservible para una impresora 3D.Hay otro detalle importante. En la foto del sensor no se ve la parte superior, por lo que no se percibe que no tenga el tornillo regulador indicado. Creo que está hecho a posta.

used to detect small metal parts

This is a run of the mill inductive proximity sensor used for determining when the sensor is up against a metal object. It's often used in industrial automation or in other similar sensing applications. This particular sensor is wired as PNP, meaning the output is either open circuit or out=VCC; if you use this with a microcontroller you may need a pulldown resistor. There's a red LED on the end of the sensor that can be used for diagnostics, which is particularly helpful for troubleshooting and installation; I also appreciate a wiring diagram is presented on the side of the sensor.I've used a number of these blue-colored inductive and magnetic proximity sensors and they're all roughly equivalent for me; they all seem to do a reasonable job of sensing and are easy to work with, with a threaded body that allows you to fine tune the height adjustment. I wouldn't necessarily count on the properties of this to be equivalent to any specific other sensor you already see in use, since various models with different trigger thresholds are available - but if you're designing your own system, this is a perfectly reasonable building block to start with.
