FAQ

The Festo PEV-1/4-B functions as a changeover switch. It has three electrical connections: common, normally open (NO), and normally closed (NC), allowing it to be integrated into various control circuits.

The switching pressure is adjusted using the setting screw located on the device, typically under a protective cap. Turning the screw clockwise increases the setpoint pressure, while turning it counter-clockwise decreases it. A pressure gauge should be used for accurate calibration.

No, the PEV-1/4-B is designed for a positive pressure range of 1 to 12 bar. It is not specified for use in vacuum (negative pressure) applications. For vacuum switching, Festo offers dedicated sensors like the VPEV or SPAN series.
