About Automatic Door


Automatic door opens when the door controller receives an activation signal by the sensor and activate the gear motor to drive the belt and pulley. When no one is detected inside the activation area, the door starts closing after a designated period of time.



Name Function
(1) Door operator An automatic door operator is a set of driving devices and controllers that opens/closes the door. It includes components such as gear motor and door controller.
(2) Maintenance switch The power to the door operator can be turned on/off easily during the maintenance of the door.
(3) Activation sensor Activation sensors are used to activate the door's openings and closings by sending a signal to the door operator.
[Notes] The above figure shows different types of activation sensors. The appropriate activation sensor shall be selected according to the use and environment.
(4) Safety sensor Safety sensors such as beam sensors detect people or objects on the door track, where it is difficult to be detected by activation sensors.
(5) Fanlight Glass or other materials mounted between the ceiling and the header.
(6) Transom Door operator is installed inside the header box.
(7) Sliding door panel Materials such as tempered glass, aluminum and stainless steel are often used.
(8) Fixed door panel Non-sliding door panel
(9) Lock Lock for the door.

About Sensor

Automatic doors are equipped with two types of sensors, an activation sensor and a support sensor.

Activation sensor

Sensor to open the door
Different types of sensors such as infrared sensor and activation switches are available. The appropriate activation sensor shall be selected according to the uses and environment.

Beam reflection type, Radio wave type
Touch Type

Safety sensor

Safety sensors are used to prevent the door panels from hitting an object or person near the door or on the door track.
Beam sensor and ultrasonic sensor are two common types of safety sensors.

Photoelectric type / Beam reflection type / Ultrasonic wave type
