What is Rapid Door Sensor System

The sensing system of fast-moving doors mainly includes radar sensors, infrared sensors, geomagnetic induction coils, etc. These sensors are used to detect objects approaching or leaving the door and transmit signals to the control system. For example, when the radar sensor detects that a vehicle or pedestrian is approaching, it will send a signal to the control system to open the door; the infrared sensor is used to detect whether there is an obstacle blocking the closing of the door. If the infrared light is blocked, the control system will immediately stop closing the door to ensure safety. In order to ensure the safety of personnel and equipment, fast-moving doors are usually equipped with a variety of safety devices, such as safety light curtains, safety edges, and emergency stop buttons. The safety light curtain is installed on both sides of the door. When a person or object passes through the light curtain, the door will immediately stop closing and open in the opposite direction. The safety edge is installed at the bottom of the door. When the door touches an obstacle, it will send a signal to open the door in the opposite direction. The emergency stop button is used to manually stop the operation of the door in an emergency.
