LiftMaster 50-HERK2 Motion Detector, 24V

The LiftMaster 50HERK motion detector is designed for precise vehicle and pedestrian detection in controlled access environments. Engineered for flexible installation, the sensor supports mounting heights from 8.2 feet up to 23 feet and delivers a maximum detection range of up to 80 feet, making it suitable for a wide range of commercial and industrial applications.

The adjustable detection field measures approximately 20 feet by 16 feet when mounted at 23 feet with a 45-degree angle. Field size and sensitivity can be fine-tuned either manually at the unit or through remote programming, allowing installers to adapt detection coverage to site-specific traffic patterns and layout constraints.

The 50HERK features dual-channel output, enabling two independent signals based on detected movement. This configuration supports advanced logic such as vehicle-only or pedestrian-only detection, as well as differentiation between forward and reverse motion. These capabilities allow seamless integration with gate operators, door controllers, and access control systems that require distinct responses.

The sensor operates on a 24-volt power supply (not included) and is intended for fixed-mount installations where accurate motion discrimination and reliable performance are required. Its configurable output and adjustable detection zone help reduce false activations while maintaining consistent detection accuracy.
