Optical Endstop Switch for 3D Printers

This optical endstop switch is designed for 3D printers using a RAMPS 1.4 control board. It provides a light-control limit function to define axis boundaries during printing. The compact module suits hobbyists and builders who need a reliable positional sensor for a single printer upgrade or repair.

Simple Three-Wire Installation

The switch connects with three wires to the RAMPS 1.4 endstop headers, requiring no soldering if the board uses standard connectors. Builders should verify pin order against the board silkscreen because reversed polarity will prevent the sensor from triggering. The plastic housing is fragile, so avoid over-tightening mounting screws.

35mm x 15mm Form Factor

Measuring 35mm by 15mm, the unit fits tight carriage spaces where mechanical switches cannot. It handles standard Cartesian and delta printer homing routines with consistent repeatability. The optical design has no moving contacts to wear out, but dust or filament debris on the sensor window can interrupt the beam and cause missed triggers.

Questions about this item

How do I verify the optical endstop triggers correctly after wiring it to my RAMPS 1.4 board?

Connect the three pins to the RAMPS 1.4 endstop header, power the printer, and watch the firmware status change when the light beam is interrupted by the printer axis.

What comes in the package and what extra parts are needed to install it?

The package contains one red optical endstop switch measuring 35mm x 15mm; you must supply the RAMPS 1.4 board and three-pin jumper wires yourself.

Which version should I choose for a standard RAMPS 1.4 setup?

This single red 35mm x 15mm optical endstop is the only version listed and is designed specifically for RAMPS 1.4 compatibility.
