Banner Engineering Q45VR3DL is a diffuse‑mode, rectangular photoelectric sensor from the Q45 family that detects reflective targets up to 1.8 m away. It provides an SPDT relay output and accepts a wide supply range of 12–250 V DC or 24–250 V AC. This model is available with a standard 2 m cable, and a W/30 variant offers a longer 30 ft (about 9.1 m) cable. The thermoplastic housing is IP67 rated, with a 5‑pin connection and a potentiometer for sensitivity adjustment. Operating temperature spans -25 °C to 55 °C, with a power‑up delay up to 100 ms and an output response time around 15 ms. The 53975 designation corresponds to this 1.8 m, diffuse Banner sensor in the Q45VR3 series.
