Microwave Sensors for Automatic Door Safety

Microwave Sensors, also known as Radar or Doppler sensors have been used to activate automatic doors for decades. Today's safety standards such as ANSI/BHMA A156.10 have been the driving force for improvement of microwave technology in automatic door applications.

The microwave sensor sends out a high frequency sound wave while listening for bounce back. When the sound wave is returned at a different frequency the sensor knows that there is a moving object within the detection zone. It then sends a signal to the internal relay, which is wired to the door control's activation input.

Bircher-Reglomat uses the latest technology in microwave detection. Utilizing the planar or flat antenna, at 24.125 GHz in the K-band range gives our sensors the capability of achieving the sharpest, most adjustable detection field possible with today's microwave technology.

Active Infrared Sensors

Active Infrared Sensors have become the most trusted and widely used technology in Automatic Pedestrian Door Safety to date. Simplicity and reliability have been bred into the newest generation of Active Infrared Sensors.

Active Infrared Sensors use invisible light to scan a defined area. The transmitter emits a beam of light into the scan zone. The light, which is reflected by the background returns to the receiver, which constantly monitors the scan zone. When a person or object enters the zone the infrared light is interrupted. It then sends a signal to the internal relay, which is wired into the door controls. One variation of this operating mode is called "background suppression". This is when the receiver only detects a change in the reflected light when a person or object enters the scan zone thus causing a  reflectance variation of the light, sending a signal to the internal relay. The benefit of background suppression is the Ride Along feature, which means the sensor can be installed on a moving door.

Bircher-Reglomat remains on the cutting edge of IR Technology providing the Automatic Door Industry with safe, reliable sensors that come in the most compact housings available in today's market, making Bircher-Reglomat products the best solution for automatic pedestrian door safety.

Microwave Sensors for Industrial Door Safety

Microwave Sensors, also known as Radar or Doppler sensors have been used to activate industrial automatic doors and gates for decades. Ever changing standards and requirements have motivated sensor manufacturers to refine this technology and develop more flexible, reliable microwave sensors for industrial use.

The microwave sensor sends out a high frequency sound wave while listening for bounce back. When the sound wave is returned at a different frequency the sensor knows that there is a moving object within the detection zone. It then sends a signal to the internal relay, which is wired to the door control's activation input.
