CGF50‑D30PB – 30 cm Diffuse Photoelectric Sensor (Square, PNP-NC)
Pickup currently not available
The CGF50‑D30PB is a high-performance photoelectric sensor designed for non-contact object detection in industrial automation systems. Built with a durable 50 mm × 50 mm square housing, it operates on the diffuse-reflective principle, detecting objects directly up to 30 cm away—no reflector required.
This version is equipped with a 3-wire PNP output, Normally Closed (NC), making it ideal for fail-safe or specific control logic applications where output deactivation upon detection is preferred.
