Industrial 4N3-CA2-M4-C2A Adjustable Pressure Switch

Industrial 4N3-CA2-M4-C2A Adjustable Pressure Switch is an industrial-grade device designed to energize or de-energize electrical circuits in response to pressure. It features an adjustable setpoint in the 2–8 psi range, enabling precise control at low pressures. The part number is 4N3-CA2-M4-C2A (also listed as 4N3CA2M4C2A), and the unit includes an SOR Static O Ring. As a pressure-activated switch, it uses the setpoint to trigger changes in electrical contact when system pressure reaches the configured level. The adjustable setpoint lets technicians tailor the switch to the desired operating pressure, potentially reducing nuisance trips. The included SOR Static O Ring supports sealing integrity in installation, contributing to reliable operation in appropriate environments.
