The KEYENCE PR‑G41CBL is a threaded‑mount diffuse reflective sensor with a 500 mm detection range and detailed specifications.
The PR‑G41CBL is a long‑distance diffuse reflective sensor featuring a threaded mount and an M12 (4‑pin) connector. It provides both NPN and PNP open‑collector outputs, with selectable Light‑ON and Dark‑ON functions, and includes a five‑turn sensitivity trimmer and a 7‑segment display for output status.
The sensor is rated IP68/IP69K for harsh environments, operates from 10 to 30 VDC, and consumes up to 450 mW. It tolerates temperatures from –20 °C to +70 °C, vibration up to 55 Hz with 1.5 mm double amplitude, and shock up to 1,000 m/s². Accessories include an instruction manual, M18 nut, and lock washer.
