The Industrial 2E21-AF357CM Pressure Switch Four Port is an industrial-grade sensing device that provides a switching action based on system pressure to control other equipment. This four-port model is factory-set to 145–175 PSI, offering a defined high/low-pressure range for reliable actuation. It is designed for use in industrial process or machinery systems where precise pressure monitoring and automatic control are required. With its four-port configuration, it supports multiple connections in a single unit, helping simplify installations in compact panels or equipment layouts.
