Festo
159259
Pressure switch PEV-1/4-A-SW27
The Festo 159259 is a pneumatic and electric pressure transducer engineered to measure relative pressure across a range of 1 bar to 10 bar using compressed air as per ISO 8573-1:2010 [7:-:-]. This industrial component features a G1/4 pneumatic connection, a 4-pin plug electrical connection, a screw-in mounting design, and a changeover switch accommodating a maximum switching frequency of 3 Hz with operating voltages up to 250 V AC and DC. It complies with CE marking as per the EU low voltage directive and UKCA marking to UK instructions for electrical equipment, operating within a medium temperature range of -20 °C to 80 °C and an ambient temperature range of -20 °C to 100 °C.

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.
