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 rangeâ€\"75% less than comparable product. Available in chemically resistant models with a PTFE- 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 indicatorsDetection Range = 200 - 8000 mmOutput Type = AnalogueBody Style = BlockMaximum DC Voltage = 30VSupply Voltage = 10 - 30 VTerminal Type = 5-Pin Euro ConnectorIP Rating = IP67Housing Material = ABS\/PolycarbonateReverse Polarity Protection = YesShort Circuit Overload Protection = Yes
