Allen-Bradley 836T-T302JX9 Pressure Control Switch

Allen-Bradley 836T-T302JX9 is a T-style electro-mechanical pressure control switch designed for traditional machine tools and heavy industrial applications, offering a 2-circuit SPDT contact block and a neon pilot light powered from 120 VAC. This 836T family device supports independently adjustable operating range and differential, with an operating range of 200–3000 psi and a differential typically in the 175–400 psi range, allowing engineers to tailor cut-in and cut-out points to their process. It uses copper-alloy bellows with a piston-type actuator (piston without seal) for sensing and has 1/4-inch NPTF female pipe connections, packaged in a Type 1 enclosure suitable for industrial environments rated for 4 and 13 use. Although configured for 4 and 13 industrial use, this model is discontinued by Rockwell Automation as of April 5, 2016.
