Allen-Bradley 836T-T351JX86X26X15X6 Pressure Control Switch

Allen-Bradley 836T-T351JX86X26X15X6 is a Bulletin 836T T-style pressure control switch used in machine tools and hydraulic or pneumatic systems to automatically start or stop equipment as pressure crosses a set point. The X26 variant specifies a Special Diaphragm and O-ring Assembly for piston-type pressure control, designed to handle challenging fluids such as phosphate ester bases, and it employs a Type 1 enclosure. The device offers a 140–1000 psi operating range with factory-set maximum operating range and minimum differential, SPDT contacts on a 2-circuit contact block, a 24 VDC red LED pilot light, and SAE 7/16-20 UNF threaded O-ring Boss Seal. Customization options exist within the 836T family to tailor trip and reset settings to specific applications, while the Bulletin 836T line remains suited for pneumatic and hydraulic applications in industrial equipment. Typical uses include machine tool fluid power control, hydraulic and pneumatic circuits, and safety/interlock functions where pressure-based switching is required.
