Description
The Optical Endstop Limit Switch is designed to detect the position of moving parts in 3D printers and CNC machines. It uses an optical sensor to identify when an object interrupts the light path, sending a digital signal to the controller. This helps the machine identify axis limits and establish accurate reference positions during homing.
Unlike conventional mechanical endstops, this optical switch operates without direct physical contact between the sensing components, helping reduce mechanical wear. Its built-in LED indicator provides a visual signal when the sensor is triggered, making operation and troubleshooting easier.
The module is suitable for use with the RAMPS 1.4 controller board and other compatible 3D printer control systems. It can be connected to the X, Y, or Z axis endstop input, depending on the machine’s configuration. Before installation, verify the board’s pinout, sensor output type, and firmware settings to ensure correct operation.
