The R24-D is a 24.125GHz microwave radar motion sensor designed for automatic glass sliding doors and commercial entrance door systems.
It is mainly used as an automatic door activation sensor. When a person approaches the entrance, the radar detects the movement and sends a relay signal to the automatic door controller to trigger door opening.
Unlike a basic indoor motion detector, the R24-D supports movement direction recognition. In directional detection mode, approaching movement can be detected while movement away from the sensor can be ignored, helping reduce unnecessary door opening. The sensor can also be configured for bidirectional detection when required. RD24-4
The sensor uses 24.125GHz microwave radar technology with an integrated MMIC planar antenna for stable motion detection and consistent sensitivity.
The radar can determine whether a person or moving object is:
This function is particularly useful for automatic sliding doors because it helps prevent unnecessary activation from people moving away from the entrance.
The sensor allows adjustment of:
The antenna can be adjusted vertically and horizontally to suit different entrance layouts.
The sensor supports installation heights below 4.5 meters, making it suitable for most commercial automatic glass door and entrance applications.
