Unidirectional Microwave Motion Sensor for Automatic Sliding Door Systems
Revised Product Description:
CNB-531 Unidirectional Microwave Motion Sensor
Precision Detection for Seamless Access Control
Core Technology & Design
Engineered with 24.125GHz microwave frequency and proprietary signal processing algorithms, the CNB-531 delivers unmatched sensitivity and stability in motion detection. Its compact, low-profile dome design (55×40×30mm) integrates seamlessly into modern architectural environments, while the curved housing enables flexible mounting angles for optimal coverage alignment.
Key Performance Advantages
- Adaptive Detection Zones:
- Adjustable vertical induction angle (15–75°) and longitudinal detection range (4m width × 3m depth) at mounting heights up to 4,000mm.
- 531D model features unidirectional motion filtering to eliminate false triggers in entry/exit zones.
- Extreme Environment Reliability:
- Operates in **-20°C to +55°C** temperatures with AC/DC 12-30V wide-voltage input.
- Certified emission safety (<5mW/cm² power density) compliant with global EMC standards.
- Energy-Efficient Operation:
- Ultra-low standby current (22mA @12V DC) and optimized emission power (<20dBm EIRP) for 24/7 sustainable use.
