Allen-Bradley 836-C7X171 Industrial Power Transformer

The Allen-Bradley 836-C7X171 pressure-control switch is an open-type unit with external copper alloy bellows that provides a precise, adjustable sensing element for industrial pressure systems; it offers a setpoint range from 4 to 150 psi and a selectable differential from 2 to 25 psi, enabling tight control of pumps, compressors, and hydraulic or pneumatic circuits. It uses a single-pole double-throw (SPDT) contact arrangement with a slow-action mechanism and no snap action, ensuring gradual actuation and reducing mechanical wear in demanding environments. Configured as Device Style C, Series A, this model is designed for panel or equipment integration without an enclosure, allowing direct exposure of the sensing element to the process while maintaining robust performance through its copper-alloy bellows. Cataloged as 836-C7X171 and part of Allen-Bradley’s 836 pressure-controls family, it is supplied by Rockwell Automation distributors and is targeted at general-industrial control tasks where a reliable, repeatable pressure threshold is essential for safety and process control.
