It features a 316 stainless steel wetted material construction for corrosion resistance and a rugged aluminum housing. The switch supports a wide voltage range including 125, 250, and 480 volts AC and 30, 125, and 250 volts DC, with an SPDT contact form. It connects via a 1\/4 inch male NPTF thread and is rated for use with air, food, oil, and water media. Licensed trades including instrumentation and industrial service technicians install this switch in process control, HVAC, and fluid handling systems.\u003c\/p\u003e\n\u003cp\u003eThis pressure switch is suited for both residential and commercial installations where watertight protection and wide media compatibility are required. Its setpoint is field-adjustable, making it adaptable across a range of pressure control scenarios. The switch is rated for operating temperatures from -20 degrees F to 150 degrees F, covering most standard indoor and outdoor service environments. It carries FM, UL, CE, and CRN certifications as standard, with optional ATEX, CSA, and IECEx listings available, making it suitable for classified hazardous locations including Class I Division 1 Groups B, C, and D and Class II Division 1 Groups E, F, and G. SIL 3 capable rating supports use in safety instrumented systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWatertight single setpoint design with field-adjustable setpoint\u003c\/li\u003e\n  \u003cli\u003e316 stainless steel wetted materials for corrosion-resistant media contact\u003c\/li\u003e\n  \u003cli\u003eWide voltage compatibility: 125, 250, 480 volts AC and 30, 125, 250 volts DC\u003c\/li\u003e\n  \u003cli\u003eSPDT contact form with amperage ratings of 0.5, 6, and 15 amps depending on circuit type\u003c\/li\u003e\n  \u003cli\u003eMaximum pressure setting of 12000 psi\u003c\/li\u003e\n  \u003cli\u003eRated for air, food, oil, and water media\u003c\/li\u003e\n  \u003cli\u003eFM, UL, CE, and CRN certified standard; ATEX and IECEx optional; SIL 3 capable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with air, food, oil, and water media systems.
