Banner QT50ULB Series Ultrasonic Block-Style Proximity Sensor, M12 x 1, 200 → 8000 mm Detection, Analogue

QT50U Series Long Range Ultrasonic Sensor. The QT50U series has been designed as a long range, programmable, ultrasonic sensor. It is suitable for use on both AC and DC circuits and is equipped with an electromechanical relay output. It comes enclosed in a shock-resistant housing, is completely sealed and is ideal for monitoring levels of liquids as well as solids. Features: Features universal supply voltage: 85 to 264 Vac (50/60 Hz) or 48 to 250 Vdc Offers SPDT electromechanical relay output for setting independent near and far window limits, for applications requiring high and low-limit sensing Available with pump-in and pump-out fill-level control on some models Senses extended range of up to 8 m Features ultrasonic dead-zone of only 2.5% of the total range—75% less than comparable product Available in chemically resistant models with a Teflon coating to protect the transducer Compensates for temperature, for greatest sensing accuracy Simplifies setup with push-button and remote TEACH-mode programming Shows status during setup and operation, using highly visible LEDs indicators
