LiftMaster 50-HERK2 Motion Detector, Microwave Technology

Keep industrial doors and access points responsive and secure with the LiftMaster 50-HERK2 microwave motion detector. Designed as an outdoor door-mount sensor, this LiftMaster motion detector uses microwave technology to sense objects moving toward or away from a programmed zone, enabling accurate vehicle vs. pedestrian discrimination that prevents unwanted door activations. The 50-HERK2’s wired DC power and rugged build provide stable connectivity and dependable performance in harsh environments, making it ideal for loading docks, gated entries, and commercial garage doors. Remote programming capability allows quick on-site adjustment so installers can tune detection patterns to site traffic and minimize false alarms. By closing doors promptly after vehicles depart, the 50-HERK2 helps improve security monitoring, reduce energy loss, and streamline access control operations. Integrate this detector with existing gate operators, security systems, or surveillance setups to enhance facility safety and operational efficiency. For reliable outdoor motion monitoring and smarter door control, specify the LiftMaster 50-HERK2 in your next access control or security project.
