Barksdale C9612-3 Pressure Switch

Barksdale C9612-3 Pressure Switch is a sealed-piston, SPDT snap-action industrial switch in the C9622 family designed for robust pressure monitoring and control in demanding environments. As part of the C9622 series, it supports single or dual setpoints and defines actuation at a decreasing pressure range of 250–2,650 psi and an increasing pressure range of 280–3,000 psi, enabling precise cut-in and cut-out points for reliable process control. The unit uses a 1/4 in. NPT female process connection, is rated for ambient operation from -40 to 165 °F, and carries a NEMA 3 enclosure rating for protection against dust and water spray in typical shop or plant settings. Gauge proof pressure is 500 psi, and the compact housing weighs roughly 1.5 lb, balancing durability with ease of mounting in control panels or on equipment. This model belongs to Barksdale’s long-life sealed piston lineup and is well-suited for industrial pressure actuation in applications such as hydraulic presses, compactors, and machine tools, where consistent performance and a rugged design are essential.
