Guardian 2.0 Radar & Infrared Sensor for Automatic Doors

Product Overview

The Guardian 2.0 is an advanced dual-technology sensor combining microwave radar and active infrared detection, specifically designed for automatic sliding doors. This powerful unit provides both motion detection and presence detection—including a new Look-Back Area function that monitors the threshold and surrounding zone to prevent entrapment and ensure safety. With certifications such as EN 16005, CE and RoHS, the Guardian 2.0 delivers reliable performance in commercial and industrial door automation environments. 

Key Features

• Dual-Technology Detection: Integrates microwave Doppler radar for motion plus active infrared for presence detection, delivering high-precision detection and anti-pinch protection. 

• Look-Back Area Function: The first row of infrared beams forms a look-back zone near the door threshold. When activated, the door remains open as long as someone is detected in the threshold area—enhancing pedestrian safety. 

• Real-Time Self-Monitoring & Auto-Learning: The system continuously checks its performance and background environment, adapting over time for increased reliability. 

• High Certification Standard: Certified to EN 16005 (Pedestrian Doorsets Using Power Operated Doors), CE and RoHS, ensuring compliance with safety and environmental standards. 

• Robust Technical Specifications:

• Technology: Microwave Doppler radar + Active infrared. 

• Motion & Presence Detection Range: 3 m to 3.5 m (typical mounting height 2-3 m). 

• Supply Voltage: DC 12-30 V (±30 %). 

• Power Consumption: < 2 W. 

• Operating Temperature: -25 °C to +70 °C.

• Housing: ABS + PC, Protection Rating IP54. 

Typical Applications

The Guardian 2.0 sensor is ideal for a wide array of automatic door use-cases, including:

• Sliding doors in retail entrances, airports, hospitals or high-traffic public buildings

• Swing or revolving doors where enhanced safety around the threshold is required

• High-performance door systems where both motion detection and presence detection are critical

• Projects requiring compliance with pedestrian door safety standards (EN 16005)
