Allen-Bradley 836T-T253J-X130X15 Pressure Control Switch

Allen-Bradley 836T-T253J-X130X15 is an electro-mechanical pressure control switch from Rockwell Automation’s 836T Style T family, built for industrial pressure sensing in traditional machine-tool applications. It uses copper alloy bellows for durable sensing and a 4-pin micro receptacle (X130) for wiring, with a 2‑circuit contact block standard in this configuration; some variants also feature a red LED pilot light at 24 V DC and a standard trip/reset setting. Operating pressure ranges vary by exact configuration, with published options for 836T-T25xJ variants including 12–70 psi, 12–150 psi, and 40–375 psi depending on the model. Copper alloy bellows may be used with water or air and other liquids or gases not corrosive to the alloy, aligning the switch with common pneumatic and hydraulic monitoring tasks.
