The Allen-Bradley 836-C8A Pressure Switch is a Style C electro-mechanical pressure control housed in a rugged NEMA Type 1 enclosure with an external copper-alloy bellows. It provides a 6–250 psi adjustable operating range with a 4–45 psi adjustable differential, and is rated for up to 500 psi line pressure and 650 psi surge, using a standard SPST contact block and a no-pilot-light configuration. Designed for panel-mount installations in general industrial environments, it relies on a standard trip/reset mechanism for reliable, low-maintenance operation.
