The FESTO PEV-1 4-B-0D Pressure Switch is a pressure-sensing electrical switch with a 250 VAC and 125 VDC rating, designed to provide an electrical signal when system pressure is within its specified range. It monitors pressures from 1 to 12 bar (15 to 175 psi), making it suitable for applications requiring a fixed-pressure threshold in pneumatic or compressed-air systems. By converting pressure information into a switch contact output, it can drive control logic, alarms, or actuator interfaces in automated equipment. This part number, PEV-1 4-B-0D, identifies this specific variant for procurement, replacement, or documentation purposes.
