Microwave Motion Detect & Infrared Presence Detect Combination Sensor For Automatic Sliding Door Activation & Safety

Doppler radar motion detect & active infrared present detectA sensor which combined the function of motion detect for door opening activation and the function of presence detect for safety protection on automatic sliding doors, folding doors, telescopic doors and circular&curve doors.

  • High sensitive Germany doppler microwave radar module, stable performance in bad temperature and humidity conditions.
  • Uni-directional microwave radar detect mode, providing better energy saving experience.
  • Smart infrared presence detect unit (self-learning) analyses the background wisely and recognizes the target objects.


Compared to light barrier (safety beam sensor), the infrared presence detect unit on M-235 has wider detecting area and smart background analysis ability, which can improves the safety and user experience at commercial or public building front entrance. Both radar motion detecting angle and infrared presence detecting angle are adjustable to satisfy different circumstance.
