Baomain Capacitance Proximity Sensor Switch LJC18A3-B-Z/BX NPN NO DC 10-30V 200mA 1-10mm

Worked perfectly as a replacement for CR10s Pro. Just needed to solder the wires to the existing connector

Great proximity sensor for anet a8 factory. I have heated alluminum bed covered in painters tape and skynet firmware.

We used this to detect whether or not an object was present, which it worked great for. Using the sensor itself to trigger a relay has worked well, but we have had 2 die in a couple years of use. Our environment is full of dust and vibrations though, so very tough on electronics. Worked great for prototyping, and we kept it in the product as it's cheap and easy to switch out if needed.

Better quality than the last one I had. Works perfectly for bed leveling my Anet A6 with aluminum heat bed and glass. I powered mine of 12v and put a diode on the signal wire(black) for the Z.

This is an amazing proximity sensor, it can detect multiple types of objects and not just metal, which includes my finger, glass, and wood.Update: After a lot of testing, I cannot get this proximity sensor to accurately produce the same results each time using an Arduino to test it. How I have it wired up: Positive (brown) to 12v+ source (atx power supply), negative (blue) to ground, and signal (black) to a zener diode, then to the Arduino.It detects objects, but the distance it detects it at varies a lot. Let's say the initial distance is 1mm, the next time it might be 0.8mm, then the time after might be 1.4mm.Even using this on a 3d printer makes it's application even worse.Either I'm using it wrong with my wiring, and the sensor is just too unreliable for precise applications to detect glass.

Works really good. The adjustment on it is very small. But, it does work.

It works to a certain resolution (.5mm or less), but it is no where near reliable enough for use with a 3d printer.

Perfecto
