Allen-Bradley 836T-T251J SER A Industrial Pressure Switch

The 836T-T251J is part of Allen-Bradley's Bulletin 836T series, known for its durability and reliability in demanding environments. This pressure switch utilizes a copper alloy bellows mechanism to detect pressure changes, actuating its single-pole double-throw (SPDT) contact block accordingly. The device allows for external adjustment of both operating range and differential, providing flexibility to meet specific application requirements. It is housed in an enclosure rated for NEMA Type 1, 4, and 13, ensuring protection against dust, water, and oil, which is ideal for machine tool applications and environments where exposure to such elements is common.
