Product description

Microswitch preassembled onto a PCB to be used as endstop for axes on your 3D printer or CNC machine. Compatible with all major electronics boards.

This great endstop solution provides you an easily mountable PCB for establishing home positions on the various axes of your 3D printer and CNC machine. Like our optical endstop solution, you can easily hook this board up to your electronics using a 3-wire cable. The microswitch should be hit by a carriage on your axis for example, to trigger a detection signal. This way your electronics can detect when an axis hits it's home position for example. This product has the following features:

  • Green detection LED, turning on upon detection
  • 3v3 as well as 5v compatible
  • Screw terminal as well as a 3-pin header to connect the board to your electronics
  • Nice, compact black painted PCB
  • High-quality SMD components

On the pcb are a screw terminal header and 3-pin header, allowing you to connect the endstop with a 3-way wire to your electronics. The module will work fine with either 3v3 or 5v input, so you can use it on the Ultratronics board as well. Connect the 3v3/5v input to the + pin, connect the - to the corresponding pin on your electronics and the detection pin to S. You will need to enable the pull-ups in your firmware when using this module and put inverting to true, as the module will give a LOW signal when it measures detection.

The Mechanical end stop pcb has two 3mm mounting holes for mounting the board to your 3D printer or CNC machine. Refer to the drawing for details of the placement of the holes.
