The switch monitors process or ambient temperature and activates a single set point SPDT contact when the setpoint is reached, making it suitable for alarm, shutdown, or process-control circuits. The operating range spans -50 to 75 degrees F, covering both sub-zero and moderate above-ambient conditions. The rigid stem measures 9\/16 inches in diameter and approximately 2-25\/32 inches in length, and the stem material is brass, providing durability in moderate-corrosion environments. Licensed electricians and instrumentation technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis temperature switch is built for local-mount installations where the sensing stem is inserted directly into a process line, tank wall, or duct through a 1\/2 inch NPT threaded connection. The SPDT contact form supports both normally open and normally closed circuit configurations, giving installers flexibility for control or alarm wiring. The -50 to 75 degrees F range suits refrigeration equipment monitoring, cold storage, HVAC low-limit sensing, and light industrial process control. Accuracy is rated at 1 percent of the mid-60 percent of full scale.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTemperature range: -50 to 75 degrees F, suitable for sub-ambient and refrigeration applications\u003c\/li\u003e\n\u003cli\u003eSingle set point SPDT contact form supports normally open or normally closed wiring configurations\u003c\/li\u003e\n\u003cli\u003eRigid brass stem, 9\/16 inches diameter by approximately 2-25\/32 inches length, for direct immersion sensing\u003c\/li\u003e\n\u003cli\u003e1\/2 inch NPT process connection for standard threaded installation\u003c\/li\u003e\n\u003cli\u003eLocal-mount design keeps the switch body at the sensing point without remote capillary\u003c\/li\u003e\n\u003cli\u003eAccuracy: 1 percent of mid-60 percent of full scale\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation temperature switch for systems requiring a 1\/2 inch NPT local-mount SPDT temperature switch in the -50 to 75 degrees F operating range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician or qualified instrumentation technician in accordance with the NEC and applicable local codes. De-energize the control circuit and, where applicable, depressurize and isolate the process line before installing or removing the switch. Apply thread sealant appropriate for the process medium to the 1\/2 inch NPT threads and hand-tighten before using a wrench to avoid over-stressing the brass stem. Verify setpoint and contact state with a multimeter before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -50 to 75 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: Single Set Point SPDT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Type\u003c\/strong\u003e: Rigid Stem\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Dimensions\u003c\/strong\u003e: 9\/16 inches diameter x 2-25\/32 inches length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProcess Connection\u003c\/strong\u003e: 1\/2 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1 percent of mid-60 percent of full scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 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: ML1H-H201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BARKSDALE","offers":[{"title":"Default Title","offer_id":51538907005234,"sku":"ML1H-H201","price":1284.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7626494d764766fccf2d36ac2b98819.jpg?v=1785829203","url":"https:\/\/voomisupply.com\/products\/barksdale-ml1h-h201-temperature-switch-50-to-75f-local-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
