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.
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.
