Festo PEV-1/4-B Pressure Switch (Part No. 10773)
The Festo PEV-1/4-B is a mechanical pressure switch designed to monitor air or water pressure within a pneumatic system and convert that pressure reading into an electrical switching signal. This makes it a crucial component for process control and safety applications in industrial automation.
This particular model is highly robust, featuring a sturdy die-cast aluminium housing for durability in harsh industrial environments. Its name indicates key features: the 1/4 specifies the pneumatic connection port size as a G 1/4-inch thread. The switch is part of the widely used PEV series of mechanical pressure sensors.
A primary advantage of the PEV-1/4-B is its adjustable switching point. Users can easily set the exact pressure threshold at which the electrical signal is triggered, typically adjustable across a broad operating pressure range of 1 bar to 12 bar. A visible scale is often included for easy visual pressure adjustment.
The internal electrical switching element functions as a changeover switch (SPDT), capable of handling a maximum switching output voltage of up to 250 V AC or 125 V DC. This versatility allows it to be integrated into various control circuits. It features a DIN type electrical connection and boasts an IP65 degree of protection, ensuring the internal components are protected against dust and water jets.
In essence, the PEV-1/4-B provides a reliable, cost-effective, and highly adjustable means of generating an electrical feedback signal based on system pressure, confirming that the system is operating within a safe or desired range.
