The CANBO M-506 is a high-performance motion detector sensor specifically developed for automatic door applications that demand precise detection control and flexible configuration. It integrates microwave motion detection for door activation with infrared safety sensing to protect pedestrians in the door area.
Designed with multiple adjustment options, the M-506 allows installers to fine-tune detection width, depth, sensitivity, output logic, and background learning time via DIP switches and adjustment screws. Dual-channel selection (A/B) helps avoid interference when multiple sensors are installed nearby, making it ideal for large projects and complex entrances.
With separate relay outputs for motion and safety signals, the M-506 can be easily connected to automatic door controllers, alarm systems, and integrated home or commercial security systems. Its strong adaptability and stable detection performance make it a preferred choice for airports, shopping malls, hospitals, and high-traffic automatic door installations.

For automatic door system: Does a universal, multi-functional sensor exist and suitable for various scenarios? One that effortlessly adapts to high-traffic office building, sensitive medical facilities, hotel and airport entrances, while guaranteeing unwavering reliability?At CANBO-SENSOR, you will
The door operator is the core to the operation of an automatic door system, and the sensor is another crucial part. Sensing technology determines the sensitivity and accuracy of an automatic door's perception of the external environment. Microwave and infrared technologies are the two most typical s
Time-of-flight, referred to as ToF technology, its core principle is to calculate the distance between the sensor and the target object by measuring the time it takes for light (usually invisible infrared laser light) to travel back and forth between the sensor and the target object.
