It features dual SPDT contacts with a maximum pressure setting of 60 psi and a repeatability rating of 0.5%, making it well suited for applications where consistent switching points are critical. The wetted components are constructed from 304 stainless steel for corrosion resistance. The switch connects via an 18-inch free lead wire and mounts through a 1\/4-inch NPTF threaded port. Licensed electricians and instrumentation technicians are the typical installers for this type of switching device.\u003c\/p\u003e\u003cp\u003eThe D2H-H18SS is appropriate for use in industrial process control, HVAC pressure monitoring, hydraulic systems, and compressed air applications where dual switching output is required. The dual SPDT contact form allows two independent circuits to be switched simultaneously at the same pressure setpoint. Its operating temperature range of -40 degrees F to 165 degrees F makes it suitable for both cold and moderately elevated temperature environments. This switch is intended for professional installation in systems requiring reliable, repeatable pressure actuation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual SPDT contact form provides two independent switched circuits from a single pressure event\u003c\/li\u003e\n\u003cli\u003e0.5% repeatability rating supports consistent and reliable switching performance\u003c\/li\u003e\n\u003cli\u003e304 stainless steel wetted materials resist corrosion in demanding fluid and gas media\u003c\/li\u003e\n\u003cli\u003e18-inch free leads simplify field wiring without the need for conduit fittings at the switch body\u003c\/li\u003e\n\u003cli\u003eWide operating temperature range from -40 degrees F to 165 degrees F\u003c\/li\u003e\n\u003cli\u003e1\/4-inch NPTF threaded port for secure, leak-resistant installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style diaphragm pressure switch replacement for industrial process, HVAC, hydraulic, and compressed air systems requiring a 1\/4-inch NPTF threaded connection and dual SPDT output.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electrician or instrumentation technician in accordance with NEC requirements and applicable local codes. De-energize all electrical circuits and depressurize the system fully before removing or installing the switch. Thread the switch into the NPTF port carefully to avoid cross-threading and verify there are no pressure leaks before restoring system pressure. Do not exceed the rated amperage limits for the voltage being switched.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Diaphragm Pressure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: (2) SPDT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure Setting\u003c\/strong\u003e: 60 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Deadband\u003c\/strong\u003e: 0.12 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deadband\u003c\/strong\u003e: 0.26 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRepeatability\u003c\/strong\u003e: 0.5%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 10A at 125\/250Vac; 3A at 480Vac\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Connection\u003c\/strong\u003e: 18 inch free leads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWetted Material\u003c\/strong\u003e: 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -40 degrees F (-40 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 165 degrees F (74 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.97 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.75 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: BARKSDALE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: D2H-H18SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BARKSDALE","offers":[{"title":"Default Title","offer_id":51540757610802,"sku":"D2H-H18SS","price":607.39,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/045499fbffa8f3c57ee748d982277cb1.jpg?v=1785863622","url":"https:\/\/voomisupply.com\/products\/barksdale-d2h-h18ss-diaphragm-pressure-switch-60-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
