It provides supplemental heat to keep the photobeam detector optics and internal components within their operating temperature range during cold-weather installations. Without adequate heating, photobeam sensors in low-temperature environments can experience condensation, fogging, or lens icing that degrades detection performance. The HU-3 is installed directly onto the compatible photobeam housing and is typically handled by security system integrators, electricians, or low-voltage technicians working on perimeter detection systems.\u003c\/p\u003e\n\u003cp\u003eThe HU-3 is suited for outdoor or semi-exposed photobeam sensor installations in climates where temperatures regularly drop to levels that can affect sensor reliability. Typical applications include perimeter security at commercial and industrial sites, access control entry lanes, and gate detection systems where year-round consistent beam alignment and optics clarity are critical. It is a replacement or add-on heating component for the OPTEX AX-series photobeam sensor product line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eProvides internal heating to maintain photobeam sensor performance in cold environments\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for OPTEX AX-series active infrared photobeam sensors\u003c\/li\u003e\n  \u003cli\u003eProtects optics from condensation, fogging, and icing in low-temperature conditions\u003c\/li\u003e\n  \u003cli\u003eDirect-mount design integrates with the existing sensor housing\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit (each)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style heating accessory for OPTEX AX-series photobeam sensors.

Disconnect and de-energize the photobeam sensor system completely before attaching or servicing the heating unit. Follow all applicable local electrical codes and the manufacturer wiring documentation for the specific AX-series sensor being serviced. Do not energize the heating unit until all connections are secured and the housing is properly closed and sealed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Photo Beams\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OPTEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HU-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OPTEX","offers":[{"title":"Default Title","offer_id":51687510835506,"sku":"HU-3","price":328.29,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/optex-hu-3-heating-unit-for-photobeam-sensor","provider":"Voomi Supply","version":"1.0","type":"link"}
