Pickup currently not available
The CGF50‑R4NA is a square-style retro-reflective photoelectric sensor designed for accurate long-range object detection up to 4 meters. Using a reflector to bounce emitted light back to the sensor, it provides stable and precise detection of opaque targets—even in dusty or ambient-light conditions.
This model features a 3-wire NPN Normally Open (NO) output configuration, allowing for easy integration into most PLCs and digital input systems requiring sinking input logic.
