CGF50‑R4NB – Retro-Reflective Photoelectric Sensor (4 m Range, NPN-NC)
Pickup currently not available
The CGF50‑R4NB is a high-precision retro-reflective photoelectric sensor capable of detecting objects up to 4 meters away using a reflector. It is designed for industrial automation tasks that demand reliable, long-range detection with minimal wiring and robust performance.
This model features a 3-wire NPN Normally Closed (NC) output, making it suitable for safety-sensitive applications or systems that require signal continuity when no object is detected.
