Johnson Controls P20EB-2 SPDT Pressure Control 100/425 PSI, 76 PSI Differential A/C Limit

The Johnson Controls P20EB-2 is a pressure control that is used mainly in air conditioning A/C systems. It performs a safety function, they measure pressure levels in the system and confirm whether the system is operating correctly. This SPDT switch is available in the pressure range of 100 to 425 PSI. It has a built-in differential of 76 PSI, that is, a change in its electrical output will occur when the pressure is 76 PSI above or below the set point. For high pressure, the switch will cut off the compressor to prevent pressure build-up on the equipment.
