It features a 1\/2 inch NPT male thread connection and a single-pole double-throw (SPDT) contact form, making it suitable for controlling or signaling equipment based on pressure conditions. The switch is rated up to 1000 psi maximum pressure setting with a 2% repeatability rating, giving installers confidence in consistent actuation across service cycles. The wetted parts are constructed from anodized aluminum. Electrical connections are made via screw terminals, accommodating a wide range of control wiring setups. Licensed HVAC technicians, plumbers, and industrial mechanics are the primary installers of this type of device.\u003c\/p\u003e\u003cp\u003eThe E1S-H15 is suited for use in hydraulic systems, pneumatic control circuits, compressor systems, and fluid handling applications where a reliable pressure-actuated switching signal is required. It operates across a temperature range of -20 degrees F to 165 degrees F, making it appropriate for both indoor mechanical rooms and moderately harsh environments. The minimum deadband is 0.1 psi and the maximum deadband is 1.20 psi, allowing for fine-tuned control in pressure-sensitive systems. This switch is applicable in both commercial and light industrial installations where NPT-threaded pressure sensing points are standard.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDiaphragm piston sensing mechanism with 2% repeatability\u003c\/li\u003e\n\u003cli\u003e1\/2 inch NPT male thread for standard pipe connections\u003c\/li\u003e\n\u003cli\u003eSPDT contact form supports normally open and normally closed circuit configurations\u003c\/li\u003e\n\u003cli\u003eRated 10 amps at 125\/250 VAC and 3 amps at 480 VAC\u003c\/li\u003e\n\u003cli\u003eMaximum pressure setting of 1000 psi with a minimum deadband of 0.1 psi\u003c\/li\u003e\n\u003cli\u003eAnodized aluminum wetted material for corrosion resistance in fluid applications\u003c\/li\u003e\n\u003cli\u003eScrew terminal electrical connections for reliable field wiring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement pressure switch for systems with 1\/2 inch NPT male threaded pressure ports requiring an SPDT diaphragm piston switch rated up to 1000 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed technician familiar with the applicable system type, whether hydraulic, pneumatic, or fluid piping. De-energize the system and depressurize the line fully before removing the existing switch or installing this unit. Verify that thread sealant compatible with the system fluid is applied to the NPT threads before installation. Electrical connections must comply with applicable local codes and NEC requirements for the voltage and amperage ratings of this switch.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Diaphragm Piston Pressure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: SPDT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure Setting\u003c\/strong\u003e: 1000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRepeatability\u003c\/strong\u003e: 2%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Deadband\u003c\/strong\u003e: 0.1 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deadband\u003c\/strong\u003e: 1.20 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 10A at 125\/250 VAC; 3A at 480 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2 inch NPT Male\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Connection\u003c\/strong\u003e: Screw Terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWetted Material\u003c\/strong\u003e: Anodized Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -20 degrees F (-29 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: 3.94 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.41 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.94 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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: E1S-H15\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BARKSDALE","offers":[{"title":"Default Title","offer_id":51541634416946,"sku":"E1S-H15","price":338.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2bf329a44eb9a7b9e801d1a1dd3f726f_30b1932e-7b91-4acd-842b-7a58380589fc.jpg?v=1785880791","url":"https:\/\/voomisupply.com\/products\/barksdale-e1s-h15-pressure-switch-1-2-npt-spdt-1000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
