Product Description

The CANBO M-235 is a professional motion sensor and presence safety sensor designed for automatic sliding door systems requiring both reliable activation and continuous safety protection. By combining microwave motion detection with infrared presence sensing, it delivers accurate door opening signals while preventing door closing when objects or people remain in the detection area.

The microwave module detects approaching movement to activate the door, while the infrared safety field continuously monitors stationary objects, making it suitable for applications where safety compliance and anti-pinch protection are critical. With adjustable sensing angles, sensitivity, and background self-learning capability, the M-235 adapts well to complex installation environments.

Engineered for system integrators, the sensor provides independent motion and safety relay outputs (NO/NC selectable), allowing seamless integration with automatic door operators, door contact devices, and access control or security systems. It is widely used in commercial buildings, hospitals, office entrances, and public facilities where stable performance and safety reliability are required.

FAQ

Q1: What types of sensors are used in automatic door systems?

A: Automatic door systems commonly use the following types of sensors:

Motion sensors (Microwave or PIR): Detect movement and trigger the door to open.

Safety sensors (Infrared): Monitor the space around the door to prevent accidental closure.

Capacitive sensors: Detect the presence of a nearby hand or body, often used in touchless activation systems.

Q2: Can automatic door sensors be installed in any environment?

A: Yes, automatic door sensors are designed to be flexible and adaptable to various environments, including commercial, residential, and public spaces. However, the installation conditions. For example, the scene with high pedestrian flow needs to be strictly fault trigger, the occasion where the ceiling needs to be installed, and different types of automatic doors.
