The cables are short, as others have said. They're marked with +, -, and solid, but make sure you double check. On one of the 6 I received, the signal and hot wire markings were swapped. The board is labeled to help verify. Oh, and I'm not sure if this is a quirk of all optical sensors, but my endstop flags that were printed in either red or white filament would not trigger the endstops. I had to print those using black filament for them to work.

Out of 6 switches 5 are either dead completely or stay in triggered state after endstop was released. Do no recommend buying these for, well, pretty much anything

They’re in a bag somewhere. Not really Converned if I see them again.

Currently using as part of a DIY auto bed leveling probe system that uses this optical end stop sensor and a 90 micro servo. I have it powered off my RAMPS 1.4 + Arduino Mega 2560 board. Works great. Had to use a jumper on the VVC + 5V pin and it seems to work without any issues.

They work well but cables are too short. The description calls them "mechanical optical". They are optical and worked well for me.I mounted them with silicone rubber that comes in a tube (RTV) nothing fancy.

I am updating my prior review since I found a problem (my fault) that I think caused me a problem with one of them. The rest are doing great and I'd recommend them since they are a good value. It's not all awesome though, some of these are assembled with the sensor a bit rotated but it has not had any impact for my use (filament out sensor). It is also true that the LED seems to stay lit in normal operation, until something fully interrupts the beam. If it is only partial, then the sensor will trigger but the LED will stay lit but slightly dimmer. Not a big deal but thought I would note it.The cables are well made with dupont single pin female connectors on the Pi end. However at 20" end to end, they are not very long. Cables for endstops should be at least a meter since there is some routing involved. If you need to run this over a few feet, you may need to either get some longer cables or splice in some wire.

I upgraded to these after using mechanical end stops on my 3D printer. With the mechanical I often had issues with the end stops not triggering. I’ve had no issues with these and they have significantly increased my trigger reliabilty. With similar price and set up I highly recommend these.
