Allen-Bradley 836T-D450J Pressure Control Switch

The Allen-Bradley 836T-D450J Pressure Control Switch is an electro-mechanical pressure-difference control (Style D) designed for traditional machine-tool applications. It provides an externally adjustable operating range from 1 to 9 psi with SPDT contacts rated to 5 A, enabling reliable switching of pneumatic or hydraulic circuits at the setpoint. Built with copper alloy bellows for durability, the 836T-D450J is housed in an enclosure suitable for NEMA Type 1, 4 and 13 environments, making it adaptable to panel, cabinet, or equipment mounting in industrial settings. This unit is part of Rockwell Automation’s 836T family of pressure controls, delivering precise differential pressure control and straightforward integration with broader Rockwell automation systems for machine tools, blowers, filters, and other processes that require a robust, adjustable pressure switch.
