Product description

The CNB-234 Side Anti-Pinch Sensor (Pet Presence Detector) is a professional safety protection device developed for automatic doors, revolving doors and swing doors. Using infrared scanning technology, it achieves a maximum sensing distance of 2 meters on one side, effectively detecting people, children and small pets near the door bottom/side to prevent pinching accidents.

Equipped with smart background learning and automatic compensation functions, it adapts to different installation environments and reflective surfaces, and automatically corrects itself against environmental changes such as vibration, deformation, shadow and sunlight, ensuring long-term stable operation. The integrated housing design is dustproof, weatherproof and aesthetically pleasing, with simple installation requiring only one side mounting. Widely used in hospitals, shopping malls, office buildings and other automatic door scenarios, it is a reliable safety accessory for door anti-pinch protection.

Automatic Door Anti-Pinch Detector, IR Scanning Obstacle Rebound

Here's a demonstration of the anti-pinch function of the CNB-234 side anti-pinch sensor!The video shows the sensor installed at the bottom/side of an automatic door. When the door is running, the sensor uses infrared scanning to detect the area under the door in real time. When a person, child, or small pet approaches the door, the sensor immediately triggers a signal, and the automatic door instantly stops or opens in the reverse direction, achieving anti-pinch and anti-pressure protection.
