Allen-Bradley 836T-T300JX21X15 Pressure Switch for Bulletin 836T

The Allen-Bradley 836T-T300JX21X15 (836T-T300JX21X15) is an industrial electromechanical pressure switch engineered for rugged monitoring, process control, and safety shutdown in industrial pneumatic and hydraulic systems. Designed as part of the Allen-Bradley Bulletin 836T line of pressure controls, this device monitors system pressure thresholds and actuates electrical contacts to signal automation controllers, initiate protective alarms, or cycle auxiliary machinery. Built for demanding manufacturing and process environments, the switch features a heavy-duty industrial enclosure that delivers robust protection against mechanical impact, vibration, dust, and environmental contamination. The unit provides reliable switching behavior to support machine tools, compressors, pumps, stamping presses, and fluid power installations. With a net weight of approximately 10 kg, it offers stable, secure mechanical mounting in heavy-duty machinery setups. The 836T-T300JX21X15 serves as a direct replacement component for scheduled maintenance, equipment refurbishment, and repair operations across automated fluid handling and factory automation lines.
