working principle of glass automatic door sensor
when someone is detected to enter, the pulse signal is transmitted to the main controller, which notifies the motor to run after judgment, and monitors the motor revolution at the same time, so as to inform the motor to apply force and enter slow running at a certain time. After the motor receives a certain operating current, it operates in a positive direction and transmits the power to the synchronous belt, which then transmits the power to the spreader system to open the door leaf; After the door leaf is opened, the controller makes a judgment. If it is necessary to close the door, inform the motor to move in the opposite direction and close the door leaf
parameter introduction of glass automatic door sensor:

3, power consumption less than 3.0va
4. Power supply voltage 110vac± 15V 50/60HZ;
5, ambient temperature -25° C -- +55° C. Humidity below 95%
6. Alarm output capacity dc50v, 0.5A (impedance load)
7, pulse count 1, 2, 3, 4 pulse adjustable
8. Preheating time is about 40 seconds
9, output duration 1.5 seconds ± 0.5 seconds
10. Sensitivity adjustment: it is adjusted by the sensitivity knob
classification of glass automatic door sensors
glass automatic door sensors include microwave automatic door sensors and infrared automatic door sensors
microwave sensor: also known as microwave radar, it reacts to the movement of objects, so the reaction speed is fast. It is suitable for places where people with normal walking speed pass. Its characteristic is that once the people near the door don't want to go out and stand still, the radar will no longer react, and the automatic door will close, which may cause people to get caught
infrared sensor: it reacts to the existence of objects. No matter whether the person moves or not, it will react as long as it is within the scanning range of the sensor. The reaction speed of infrared sensor is slower than that of microwave sensor
this is a brief introduction to the working principle of glass automatic door sensor and the classification of glass automatic door sensor. I hope it will be helpful to you. Please look forward to more information
