Unlike passive infrared sensors that rely solely on heat signatures, microwave-based detection uses radar-frequency energy to sense movement, making it effective in environments with variable temperatures or obstructions that can challenge standard PIR units. This sensor is typically installed by licensed electricians or access control technicians as part of a gate, door, or entry system where reliable, hands-free activation or detection is required.\u003c\/p\u003e\u003cp\u003eThe 50-HERK2 is suited for outdoor installations in both residential and light commercial settings. It is commonly integrated into automatic gate systems, sliding or swing door entry points, and perimeter security setups where consistent motion detection is needed regardless of ambient temperature swings. The unit is sold individually and is appropriate for new installations or direct replacement of an existing microwave sensor in a compatible access control system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrowave radar detection technology for reliable outdoor performance\u003c\/li\u003e\n\u003cli\u003eDesigned for outdoor PIR and motion sensor applications\u003c\/li\u003e\n\u003cli\u003eSold as a single unit for straightforward replacement or new installation\u003c\/li\u003e\n\u003cli\u003eSuitable for gate, door, and perimeter access control systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or addition for outdoor access control and automatic gate systems that support microwave motion detector inputs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electrician or licensed access control technician. Disconnect power to the gate operator or door control system before wiring the sensor. Follow all applicable NEC guidelines for low-voltage wiring and outdoor-rated enclosures. Mount the sensor at the manufacturer-recommended height and angle to achieve the intended detection zone coverage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetection Type\u003c\/strong\u003e: Microwave\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Outdoor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Per Pack\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LIFTMASTER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 50-HERK2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LIFTMASTER","offers":[{"title":"Default Title","offer_id":51564246335794,"sku":"50-HERK2","price":1409.18,"currency_code":"USD","in_stock":false}],"url":"https:\/\/voomisupply.com\/products\/liftmaster-50-herk2-microwave-motion-detector","provider":"Voomi Supply","version":"1.0","type":"link"}
