Festo
529977
Pressure sensor SDE1-V1-G2-HQ4-L-P2-M8
The Festo part number 529977 is a piezoresistive pressure sensor with an integrated display configured for measuring differential and relative pressure within a 0 to -1 bar range. It features 2xPNP switch outputs with freely programmable and switchable functions, supporting a maximum output current of 150 mA and operating on a 15 to 30 V DC voltage range with pulsing short circuit strength and polarity protection for all electrical connections. Certified with RCM Mark and c UL us - Recognized (OL) approvals and conforming to RoHS while remaining free of copper and PTFE, this component operates in medium and ambient temperatures from 0 to 50 °C using compressed air according to ISO8573-1:2010 [7:4:4] where lubricated operation is possible. Submit the exact part number, quantity, and application requirements to receive a formal quotation.
