Allen-Bradley 836-C7A Pressure Control Type 1 Enclosure

The Allen-Bradley 836-C7A Pressure Control is an electromechanical pressure switch from the Bulletin 836 family, configured with a Type 1 enclosure and external copper alloy bellows for rugged industrial environments. It delivers a 4–150 psi switching range, with an adjustable operating range of 2.5–25 psi and an adjustable differential to tailor the gap between actuation and release pressures. The device is rated for up to 300 psi maximum line pressure, with a 375 psi occasional surge rating, making it suitable for demanding pneumatic and hydraulic applications. Designed for general industrial use, Device Style C, the Type 1 enclosure protects the sensing element while providing reliable electrical isolation in indoor or moderate environments. The 836-C7A is intended to start, stop, or regulate equipment by energizing contacts as the process pressure crosses the setpoint, making it a practical choice for compressors, pumps, pressure boosting systems, and other process lines that require dependable pressure control. Its compact form factor supports installation in control panels and other restricted spaces, while the copper alloy bellows enhance durability against typical industrial fluids and ambient conditions.
