The GuardRay Active Infrared Presence Sensor is a high-performance safety solution for automatic door systems. Using advanced active infrared distance-measuring technology, GuardRay continuously monitors the presence area beneath the door, ensuring reliable protection for pedestrians and objects during door operation.
Designed for professional door automation applications, GuardRay combines fast response, stable detection, and strong anti-interference capability, making it suitable for both indoor and semi-outdoor environments.
Active Infrared Presence Detection
Utilizes distance-measuring infrared technology to accurately detect stationary and moving objects within the detection area.
Fast Response Time
Ultra-fast response time of 64 ms, ensuring immediate door reaction and enhanced user safety.
Flexible Installation Height
Supports installation heights from 0.6 m to 4.5 m, suitable for various door types and site conditions.
Compact Detection Area
Detection area of 40 × 70 mm at 2 m and 50 × 100 mm at 3 m, optimized for precise presence monitoring.
Reliable Environmental Performance
Operates within -30°C to +60°C and up to 95% RH (non-condensing), with IP53 protection class.
Advanced Anti-Interference Design
Built-in DIP switch settings support anti-interference optimization and monitoring input for enhanced door safety.
