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

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

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.

They work as expected. When the bullet feed tube is filled the collator stops.

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.
