Touchless 3D Printer Endstop Optical Sensor

No touch limit switches make 3d printing easier than ever.

In stock


Every 3D printer has limit switches.  When the 3D printer starts a print job it touches the switches to sense the position of the printer head, and then counts the steps to measure the movement from there.  If your printer has a physical contact switch, you may find after several prints that the switch has been nudged a little bit and the printer needs to be recalibrated.  Who needs that hassle?  Get touchless limit switches that never move!

This touchless limit switch has two mounting holes and a sesnor gap. When an object passes through the gap the beam of light is interrupted, which triggers the switch and causes the voltage on the signal wire to rise.
