PRODUCT DESCRIPTION
ALLEN BRADLEY 836-C3A - Electromechanical Pressure Switch
The ALLEN BRADLEY 836-C3A is an electromechanical pressure switch designed for robust industrial pressure monitoring and control applications. This Bulletin 836 series device utilizes a diaphragm-actuated mechanism to provide reliable contact closure or opening based on a user-defined pressure setpoint. It is engineered for integration into hydraulic, pneumatic, and lubrication systems, as well as general process control and pump/compressor automation.
