Omron Optical Limit Switch

This Optical Homing Sensor uses the genuine OMRON EE-SX671P-WR 1M slot-type photo micro sensor for reliable, repeatable CNC homing and position sensing.

This L-shaped, through-beam sensor detects an interrupting tab or flag as it passes through the 5 mm sensing slot. Light-ON and Dark-ON operation can be selected to match the machine control system and wiring requirements.

Compatibility and Installation

This sensor provides a PNP output and operates from a 5–24V DC supply. Confirm that your CNC controller accepts PNP inputs and is compatible with the sensor’s voltage, output configuration, wiring, and selectable Light-ON/Dark-ON operation before installation.

The installer is responsible for proper mounting, alignment, wiring, and machine configuration. Always verify the wiring and controller requirements before applying power.
