Festo
8181220
Pressure sensor SPAF-B11R-G18M-N-PNLK-M12
The Festo 8181220 is an industrial component utilizing a piezoresistive pressure sensor to measure relative pressure across a range of -0.1 to 1 MPa (-1 to 10 bar, -14.5 to 145 psi) with an overload pressure rating of 1.5 MPa (15 bar, 217.5 psi). Operating with compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases within a 0 °C to 50 °C medium and ambient temperature range, it achieves an accuracy of 1.5 %FS and a repetition accuracy of 0.3 %FS. This unit features a switchable PNP/NPN switching output supporting window comparator, threshold value comparator, and variable hysteresis functions with a 3 ms on time, alongside RCM, CE, and UKCA compliance while remaining RoHS compliant.

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.
