Pickup currently not available
The CGF50‑R4NC is a rugged, retro-reflective photoelectric sensor with a detection range of up to 4 meters using a standard reflector. Designed for non-contact object detection in industrial environments, it emits light that reflects back from a reflector—triggering the sensor when an object interrupts the beam.
This model is equipped with a 3-wire NPN output in a Normally Closed (NC) configuration, making it ideal for use in fail-safe circuits, alarm triggers, or environments where the control system expects an "on" signal in normal (no object) conditions.
