Festo
529978
Pressure sensor SDE1-V1-G2-HQ4-L-PU-M8
The Festo 529978 is a piezoresistive pressure sensor featuring an illuminated LCD display and a -1 bar pressure measuring range for differential and relative pressure monitoring. It operates on a 15 to 30 V DC operating voltage range with a 0 to 10 V analog output, 150 mA max output current, and QS-4 pneumatic connection. Featuring a switchable and freely programmable switching function with Teach-In setting options, the unit offers a 2 to 99.8 % threshold value setting range and a 0 to 90 % hysteresis setting range. Built with an IP65 protection class, 4-pin M8x1 round plug electrical connection conforming to EN 60947-5-2, and pulsing short circuit strength, it supports any assembly position and includes polarity protection for all electrical connections.
