Product Description

M-204G/GD Unidirectional Microwave Radar Motion Door Sensor

Microwave doppler radar motion detect sensor for automatic door activation.
Used on various automatic doors for activation, high sensitivity, fast and accurate response, excellent microwave penetration and interference resistance, widely applied in commercial, industrial and automation fields with high demand.

In addition, we should also have a unidirectional microwave sensor, whose main feature is that it only detects the approaching signal, shielding the departuring signal. That is, when entering the sensor is effective, when leaving the sensor will not respond again, resulting in a false door open signal.

Motion detect active infrared sensor for automatic doors' activation opening. Compared with infrared sensors, microwave sensors have a wider detection range, high sensitivity, fast and accurate response. In the large passenger flow of shopping malls, airports and other public places of the automatic door, the activation of microwave sensor is a good choice. And can accurately adjust the detection area, flexible to respond to a variety of environmental occasions.
