Allen-Bradley 836T-T300JX9 Pressure Control

Allen-Bradley 836T-T300JX9 is an electro-mechanical pressure control switch (Bulletin 836T) used in traditional machine-tool applications to regulate hydraulic or pneumatic pressure via a controlled switch network. The unit provides an adjustable pressure setpoint in the 40 to 550 psi range and uses a SPDT contact block configured for two circuits, with inlet/outlet fittings available as NPTF 7/16-20 UNF-2B and SAE 9/16-18 UNF-2B O-ring boss seals, all housed in Enclosure Type 1 for indoor environments. Rockwell Automation lists 836T-T300JX9 as discontinued as of April 5, 2016, with no planned replacement, so this model appears in legacy catalogs and is often sourced from distributors for legacy equipment.
