The SMC ISG 220-031 (722998) is a pressure switch for shipboard control and monitoring circuits, changing the state of its contacts in response to the pressure it senses. It works across a range of 0.02 to 0.7 MPa (0.2 to 7.1 kgf/cm²), with a differential of 0.02 to 0.45 MPa (0.2 to 4.6 kgf/cm²) and a proof pressure of 1.5 MPa (15.3 kgf/cm²). Its contact configuration is 1A 1B. This unit is offered in New Open Box condition.
