Allen-Bradley 836T-T352J Pressure Control Relay

The Allen-Bradley 836T-T352J Pressure Control Switch is a two-circuit electromechanical pressure control designed for traditional machine-tool applications, providing automatic actuation of hydraulic or pneumatic circuits as system pressure changes. Constructed with a copper-alloy bellows and a piston without seal, it targets rugged industrial service and pairs with a 2-circuit contact block for flexible control wiring. It delivers an adjustable operating range from 400 to 3000 psi with a 300 to 400 psi differential, and it supports occasional surge pressures up to 1500 psi, making it suitable for systems that experience short transient spikes. The 836T family designation denotes a T-style pressure control used in machine tool environments, with the 836T-T352J variant specifically described for 400–3000 psi operation and two-circuit switching. Typical applications include machine tools, presses, and other industrial equipment where precise setpoints govern tool movement, clamping, or actuator actuation; the device’s contact block configuration supports straightforward integration into standard control circuits.
