Banner Engineering QT50UVR3W Photoelectric Sensor

Banner Engineering QT50UVR3W is a universal‑voltage, window‑limit ultrasonic sensor in the U‑GAGE QT50U family, designed for precise non‑contact distance and level sensing with a robust relay output. It detects targets from 200 mm up to 8 m (8 ft to 26 ft) using a 75 kHz transducer and provides an SPDT electromechanical relay for switching load currents, with a 2 m, 5‑wire cable configuration on the W variant. The rectangular housing is made from PBT and is designed for reliable operation in challenging environments, including chemical‑resistant applications. This model supports remote teach and clear object detection, and offers window‑limit operation with both normally open and normally closed outputs to suit larger load requirements. Common applications include fill‑level monitoring and pump‑in/pump‑out level control, as well as general position or presence sensing in tanks, bins, conveyors, and similar setups. The QT50UVR3W is a universal supply voltage sensor (AC or DC), making it compatible with a wide range of control systems and power platforms without needing a dedicated supply, and it is part of Banner’s U‑GAGE line known for durable, non‑contact measurement in industrial automation.
