Festo
8181221
Pressure sensor SPAF-V1R-Q4-L-PNLK-VB-M8
The Festo 8181221 is an industrial piezoresistive pressure sensor designed to measure relative pressure from 0 to -0.1 MPa (0 to -1 bar, 0 to -14.5 psi) with an overload pressure rating of 0.5 MPa (5 bar, 72.5 psi). This component features a switchable PNP/NPN switching output, configurable switching functions including window and threshold comparators, and a 3 ms on time for compressed air or inert gas media within a 0 °C to 50 °C operating temperature range. It complies with RCM, CE EMC and RoHS directives, UKCA EMC and RoHS instructions, and maintains a full scale accuracy of 1.5 %FS with a 0.3 %FS repetition accuracy.

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.
