Optical Endstop Optical Limit Switch for 3D Printers RAMPS 1.4

The optical endstop is a reliable endstop / switch solution for any type of 3D printers and other CNC and/ or 3D tools. This fully assembled plug and play Optical (Opto) Endstop Light Control Limit Switch is very suitable for your 3D printing or CNC project. The Optical Endstop Switch will immediately output the digital control when the light is blocked and turn the LED on.

Compatible with RAMPS 1.4 board
