GeeekPi 6Pack Optical Endstop with Velcro 1M Cable Optical Switch Sensor Photoelectric Light Control Optical Limit Switch Module for 3D Printer

I used them to replace the switch endstops on my Delta Kossel Pro. I no longer use Automatic Bed Levelling because these optical switches get my nozzle to the glass within .05mm EVERY TIME.Works great on the Duet2 Wifi. No complaints.

The package only had 1 cable connector. It shows that it should come with 6. I didn't get what I ordered.

Needed an easily mountable solution for 3D Printer or Laser Engraver. These worked well. Took a bit to fasion a mount for them because the pins protrude thru the bottom of the PC Board. I would have preferred the Signal Terminal go LOW when active (Blocked) or, better yet, be selectable, but the output state is correct in the description. The Indicator LED is great and made final adjustment easy.
