836-C9 | Allen-Bradley | 1/4" FNPT Industrial Pressure Control

Allen-Bradley 836-C9 Style C Industrial Pressure Control Switch

Product Overview

The Allen-Bradley 836-C9 is a heavy-duty, electro-mechanical pressure control switch engineered for precision monitoring in demanding industrial environments. As part of the venerable 836 series, the 836-C9 features a Style C design with external copper alloy bellows, providing exceptional durability and sensitivity for air, water, and non-corrosive oil systems. This switch is designed to handle an adjustable operating range between 35 and 375 PSI, with a high maximum line pressure rating of 900 PSI. Its rugged construction and snap-action SPST contacts make it an ideal choice for high-cycle applications where reliability is paramount for system protection and automation.

Industrial Application Scenarios

• Air Compressor Systems: Automatically managing motor start/stop cycles based on tank reservoir pressure levels.

• Hydraulic Power Units: Monitoring system pressure to prevent over-pressurization and ensure consistent hydraulic force.

• Water Pump Control: Regulating pressure in industrial cooling loops or municipal booster stations.

• Lubrication Systems: Ensuring machinery receives proper oil pressure before allowing operation, acting as a critical safety interlock.
