It provides adjustable setpoint capability across a range of 30 psi to 1000 psi, with a maximum pressure rating of 1500 psi. The switch features dual SPDT (2x SPDT) contacts and accepts a wide range of supply voltages including 125V AC, 250V AC, 480V AC, and 24 to 30V DC. The aluminum housing and 1\/4-inch NPTF process connection make it a durable choice for demanding environments. Licensed HVAC technicians, plumbers, and industrial service professionals install this type of switch in pressure control and safety cutout circuits.\u003c\/p\u003e\u003cp\u003eThe H100-705 is suited for residential, commercial, and light industrial systems where reliable pressure sensing and switching is required. It is appropriate for use in compressed air, hydraulic, gas, or water pressure circuits within its rated pressure and temperature range. The switch can serve as a safety control, a process limit switch, or an alarm trigger depending on the application. Its Type 4X enclosure rating makes it suitable for wet, washdown, and corrosive environments. The 1\/2-inch NPT female electrical connection accommodates standard conduit fittings for protected wiring installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAdjustable setpoint range: 30 psi to 1000 psi\u003c\/li\u003e\n\u003cli\u003eMaximum pressure rating: 1500 psi\u003c\/li\u003e\n\u003cli\u003eDual SPDT contact form supports independent circuit switching\u003c\/li\u003e\n\u003cli\u003eMulti-voltage rated: 125V AC, 250V AC, 480V AC, and 24 to 30V DC\u003c\/li\u003e\n\u003cli\u003eType 4X enclosure for wet and corrosive location use\u003c\/li\u003e\n\u003cli\u003eSIL 2 (HFT=0) and SIL 3 (HFT=1) Safety Integrity Level certified\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -40 degrees F to 160 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose diaphragm pressure switch for use in commercial and industrial pressure control circuits where a 1\/4-inch NPTF process connection and multi-voltage SPDT switching are required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician or qualified service technician in accordance with applicable NEC requirements. De-energize all circuits and relieve system pressure completely before removing or installing the switch. The 1\/2-inch NPT female electrical port should be sealed with a conduit connector or fitting rated for the enclosure type to maintain the Type 4X rating. Do not exceed the rated maximum pressure or temperature limits stated on the device label.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Adjustable Pressure\u003c\/strong\u003e: 30 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Adjustable Pressure\u003c\/strong\u003e: 1000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure Rating\u003c\/strong\u003e: 1500 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Deadband\u003c\/strong\u003e: 3 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deadband\u003c\/strong\u003e: 20 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 125V AC, 250V AC, 480V AC, 24 to 30V DC, 125V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 0.03A, 0.5A, 1A, 2A, 15A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: 2x SPDT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProcess Connection Thread Size\u003c\/strong\u003e: 1\/4 inch NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Connection\u003c\/strong\u003e: 1\/2 inch NPT Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Rating\u003c\/strong\u003e: Type 4X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 160 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetpoint Adjustability\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: CCC, SIL 2 at HFT=0, SIL 3 at HFT=1, UAE Certified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: UNITED ELECTRIC CONTROLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H100-705\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UNITED ELECTRIC CONTROLS","offers":[{"title":"Default Title","offer_id":51559675494706,"sku":"H100-705","price":488.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fcd5d2f89022cad6554e576cffd21951.jpg?v=1786437882","url":"https:\/\/voomisupply.com\/products\/united-electric-controls-h100-705-diaphragm-pressure-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
