Twidec/M12 Approach Sensor Inductive Proximity Switch NPN NO DC 6-36V, 4mm Detecting Distance LJ12A3-4-Z/BX

it' s perfect thanks

Worked great. Allows enough current for a 12 volt automotive relay to work. Was able to fit in with a handmade bracket to the shift gate of the stock Can-Am X3 to allow for reverse lights to come on automatically when put in the reverse position.

I purchased this inductive sensor as a bed leveling sensor for my Monoprice Select V2. After upgrading the Marlin firmware and making a few changes in the Configuration.h tab I got the sensor to work. I connected the sensor to an Arduino Uno powered with a 9v battery. The sensor is being powered with the input voltage (9v) which gives the sensor enough of a sensing distance that the sensor could be places slightly higher than the hotend nozzle (.12mm). This setup supplied enough voltage to the sensor to get it to detect the aluminum print bed. The higher the input voltage to the sensor the greater the detection distance. I will be trying a voltage divider where the sensor connects to the the Arduino Uno so I can get a higher voltage through the sensor and a lower voltage to the arduino and MKS Gen L board.

TLDR, Doesnt work as expected. It doesnt drop voltage fully, it leaks voltage.I am not new to 3D printers, been building them and using them for over 5 years. Lately my 4 yr old Z probe sensor quit in my CoreXY, so i got this as a replacement. After wiring this sensor trusting it will work, it didnt and crashed my bed. The 10k ohm internal resistance seems ok, being NO, the output voltage seems ok, but when triggered it leaks voltage and wont trigger the end stop.Pulled an old LJ18A3 i had in a drawer and that one works fine as expected.Bad batch, not happy it didnt work.

I installed this switch and a magnet on my shift lever of my RZR to cut out the noisy SBC pre-filter when in park. That way it isn't on when starting or idling in park. Works every time to de-energize the relay when in park. I like the no-contact aspect that eliminates the trauma of slamming the lever into park to activate a mechanical switch. I tried that with a micro switch and it broke in a short time. This switch has been working fine for several trips now.

Like - light weight ~ 45g, flexible wire, repeatable , reasonable price.M48 P9 test Mean: -0.110833 Min: -0.113 Max: -0.108 Range: 0.005 Standard Deviation: 0.001667I used the Ender 3 24V as power source.I chose the PNP model so the output is 24V. I used a voltage divider ( 4.7K and 1K ) to reduce the voltage.Only two issues - You need a metal build surface , I use PEI on spring steel, You need to make a voltage divider to connect it to the Z_End_Stop on the ENDER 3 control board.

I bought this to use as a cutoff switch for my bullet/case collator instead of a mechanical micro switch or optical switch. Wiring is very easy and it works like a champ.

Does not work as drop-in replacement for mmu2. Unit functional but not the right size or sensitivity for my project
