Allen-Bradley 836T-T251JX9 Pressure Control Switch

Allen-Bradley 836T-T251JX9 Pressure Control Switch is a Bulletin 836T device that senses hydraulic or pneumatic pressure and actuates a control circuit when the setpoint is reached, enabling automatic interlocks or sequencing in equipment such as air compressors, hydraulic presses, and other fluid-power systems. As part of the 836T family, it is designed for rugged industrial environments and is commonly used in transportation and machine-tool applications to reliably switch electrical circuits in response to pressure changes. 836T pressure controls are built to support robust enclosure configurations for harsh environments and typically use SAE 9/16-18 UNF-2B threaded O-ring boss seals, facilitating secure connections in hydraulic/pneumatic lines. The T251JX9 suffix designates the exact variant within the 836T lineup, distinguishing it from other trip-point and connection options in the series.
