Festo VPEV-1/8 Pressure Switch
Adjustable switching for vacuum or positive pressure
The Festo VPEV-1/8, part 150261 is an adjustable vacuum/pressure switch with a changeover contact. The manufacturer lists a relative-pressure measuring and operating range of −1 to +1.6 bar.
The documented vacuum switching threshold is adjustable from −0.95 to −0.2 bar. After the specified conversion, the positive-pressure threshold range is 0.16–1.6 bar. Follow the conversion instructions for the intended setup.

Connections and contact-load selection
The switch has a G1/8 pneumatic port and a DIN 43650 Form A electrical connection. Its listed maximum switching frequency is 3 Hz, with IP65 protection and medium/ambient limits of −20 to +80 °C.
Select the electrical contact load from the applicable AC or DC load category and manufacturer rating. Maximum voltage and current figures should not be combined into an unrestricted rating for every load.
For a replacement, record the current switching threshold, circuit voltage, load type and connector arrangement. These details distinguish a suitable switch setup from a mechanically similar device.

Festo products listed
Two items show the two halves of a pneumatic circuit. The VTUG is a valve terminal: a manifold that carries a row of directional valves with common air supply and a shared electrical connection. The DSBC-32-100-PPVA-N3 is an ISO standard cylinder. Its type code reads as 32 mm piston diameter and 100 mm stroke, with adjustable end-position cushioning and a piston magnet for position sensing.Ordering Festo parts: what we need
Festo parts carry both a type code and a numeric part number on the label. Send both when you can; the part number is the shortest route to an exact match. For a cylinder give the full type code as on the listed DSBC example, plus mounting parts and proximity switches if required. For a VTUG valve terminal send the configuration code or a label photo: number of valve positions, valve functions, coil voltage and the electrical connection type all vary from one terminal to the next.Browse Festo products by category: Solenoid Valve, Valve Actuator.
