Glass automatic door sensors are mainly used for automatic doors, revolving doors, fast shutter doors, industrial sliding doors and so on. Today we take a look at the automatic glass door sensors works and glass automatic door sensor classify it.
Glass Automatic Door Sensor Working Principle
When it is detected that someone enters, the pulse signal is transmitted to the master controller. After the master controller judges, the master motor is notified to run, and the number of motor revolutions is monitored at the same time so as to notify the motor to increase the force and enter the slow running at a certain time. After the motor gets a certain operating current, it will run in a forward direction, transmit the power to the timing belt, and then the power will be transmitted to the spreader system through the timing belt to open the door. After the door fan is opened, the controller will make a judgment. If the door needs to be closed, the motor will be informed To exercise, close the door leaf.
Glass automatic door sensor parameter introduction:
1, the installation height of 2.5m or less;
2. Longitudinal detection range: full beam 12°--20°, side beam 3.5°--1.5° (5 segments);
3, power consumption below 3.0VA;
4, the power supply voltage 110VAC ± 15V 50/60HZ;
5, the ambient temperature -25 °C - +55 °C, humidity below 95%;
6, alarm output capacity DC50V, 0.5A (impedance load);
7, pulse counting 1, 2, 3, 4 pulse adjustable;
8, warm-up time is about 40 seconds;
9, the output duration of 1.5 seconds ± 0.5 seconds;
10. Sensitivity adjustment: Adjust by sensitivity knob.
Glass Automatic Door Sensor Classification
Glass automatic door sensors have microwave automatic door sensors and infrared automatic door sensors.
Microwave sensor : Also known as microwave radar, it responds to the movement of objects, so the response speed is fast. It is suitable for places where normal walking speeds pass through. It is characterized by the fact that once people near the door do not want to go out and stay still, the radar No longer respond, the automatic door will be closed, there may be clip phenomenon.
Infrared sensors : React to the presence of an object. Regardless of whether the person is moving or not, it will respond as long as it is within the scanning range of the sensor. Infrared sensors respond more slowly than microwave sensors.
