Allen-Bradley 836-C7A Pressure Control Switch

Allen-Bradley 836-C7A pressure control switch is a Style C, Type 1 enclosure device with external copper alloy bellows, designed for general industrial use in air, oil, and water systems. It provides an adjustable operating range of 4 to 150 psi and an adjustable differential of 2.5 to 25 psi, with a maximum line pressure of 300 psi and occasional surge pressures up to 375 psi. Pressure connections are 1/4 in NPTF internal pipe thread, and electrical connections use a cable gland with a two-circuit SPST NC contact block configuration; the unit is rated for NEMA Type 1 environments and employs external bellows made of copper alloy for durability.
