Automatic doors are widely used in commercial buildings, hospitals, shopping malls, office entrances, and public facilities, where fast response, stable triggering, and environmental adaptability are essential. As the primary trigger device, the motion sensor directly determines the door’s opening efficiency and user experience.

FALCON Automatic Door Microwave Radar Motion Sensor is specifically designed to meet these requirements. Using 24.150 GHz microwave Doppler radar technology, FALCON provides reliable motion detection, flexible installation, and stable performance, making it an ideal activation solution for various automatic door systems.

Application Challenges in Automatic Door Systems

Automatic doors often face the following challenges:

• Missed triggering when users approach slowly

• False activation caused by vibrations or reflective surfaces

• Limited installation flexibility in different door structures

• Environmental interference from lighting or temperature changes

• High-frequency operation requiring long-term stability

These challenges require a motion sensor that is responsive, adjustable, and resistant to interference.

FALCON Application Advantages in Automatic Doors

1. Reliable Microwave Doppler Motion Detection

FALCON adopts microwave Doppler radar technology (24.150 GHz) to detect movement based on speed and direction. With a minimum detection speed of 5 cm/s, it can accurately detect slow-moving pedestrians approaching the door, ensuring smooth and timely door activation.

Unlike infrared solutions, microwave radar is less affected by ambient light, shadows, or temperature changes, providing consistent performance in both indoor and semi-outdoor environments.

2. Flexible Detection Field Adjustment

FALCON features a built-in potentiometer for detection field size adjustment, allowing installers to precisely control the radar coverage area. In addition, the sensor supports wide angle adjustment:

• Vertical inclination: 0° to 90°

• Lateral inclination: −30° to +30°

This flexibility helps avoid unwanted detection from surrounding walls, passing traffic, or reflective surfaces, significantly reducing false triggering in complex installations.

3. Multiple Installation Options for Different Door Types

FALCON supports both wall mounting and ceiling mounting, making it suitable for:

• Sliding doors

• Swing doors

• Revolving doors

With a recommended mounting height of 1.8 m to 3 m, the sensor easily adapts to standard automatic door configurations in commercial and public buildings.

4. Fast Response and Stable Output

With low power consumption (< 2 W) and a solid-state relay output, FALCON provides fast and reliable signal transmission to the door controller. This ensures immediate door response when motion is detected, while maintaining long service life and stable operation under frequent use.

5. Strong Environmental Adaptability

FALCON is designed for demanding environments:

• Operating temperature range: −25 °C to +70 °C

• Protection class: IP54

• Durable housing made of ABS & polycarbonate

These features ensure reliable operation in high-traffic entrances, where vibration, dust, or temperature fluctuations are common.

6. Easy Installation and Maintenance

Clear wiring definitions, visual LED indication, and straightforward field adjustment simplify installation and commissioning. By properly adjusting the antenna angle and detection field, installers can quickly achieve optimal performance while minimizing maintenance requirements.

Typical Application Scenarios

• Commercial building automatic sliding doors

• Office and hospital swing doors

• Shopping mall entrances

• Public facility revolving doors

Conclusion

FALCON Automatic Door Microwave Radar Motion Sensor delivers a reliable, flexible, and cost-effective activation solution for automatic door systems. By combining precise microwave motion detection, adjustable detection field, wide installation flexibility, and robust industrial design, FALCON ensures smooth door operation, reduced false triggering, and improved user experience.

For automatic door applications where stable motion detection and long-term reliability are essential, FALCON is a dependable choice.
