Festo
540202
Pressure sensor SDE3-V1Z-B-HQ4-2N-M8
The Festo 540202 is an industrial piezoresistive pressure sensor featuring an integrated display for measuring differential pressure within a range of 0 MPa to -0.1 MPa (0 bar to -1 bar, 0 psi to -14.5 psi). This component operates with compressed air conforming to ISO 8573-1:2010 [7:4:4], supporting a medium and ambient temperature range of 0 °C to 50 °C and an overload pressure threshold of 0.5 MPa (5 bar, 72.5 psi). It is equipped with two NPN switching outputs with freely programmable and switchable functions, delivering a repetition accuracy of 0.3 %FS and an overall accuracy between 2 %FS and 3 %FS. Certified with RCM and c UL us-recognized (OL) marks while carrying CE and UKCA compliance for EMC and RoHS directives, the unit includes RoHS-compliant materials and permits lubricated operation.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
