Festo
The Festo 542891 is a piezoresistive pressure sensor designed to measure relative pressure across a 0 bar to 10 bar operating range using compressed air as per ISO 8573-1:2010 [7:4:4]. Featuring a PNP switching output with a threshold value, variable hysteresis, N.O. contact function, and 100 mA maximum output current, this unit operates on a 15 V to 30 V DC voltage range with short-circuit protection and supports lubricated operation within a medium and ambient temperature range of 0 °C to 50 °C. It maintains a repetition accuracy of 0.3 %FS and a temperature coefficient of 0.05 %FS/K, while carrying RCM, c UL us, CE, and UKCA compliance along with RoHS material conformity.

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.
For a faster response, include quantity, condition, and delivery destination.
