separate the exterior and interior of the industrial field with COAD's high-speed automatic doors. The COAD high speed door is rolled up from the bottom and does not take up space. Therefore, even a small factory can increase the use of space as much as possible. The switching speed can be set up to 3 m/s, and the door can be opened and closed 15 times faster than the manual switching speed, which is typically between 0.2 and 0.5 m/s. We apply advanced sensors such as the LOOP sensor, the ultrasonic sensor, and the infrared sensor to detect objects as they approach them and open the door. Thanks to these sensors, you can get in and out of here quickly without stopping to wait! Besides these, we have safety sensor 2 sets. Photosensors consists of a light emitting part and a light receiving part, which are attached to the left and right sides of the industrial automatic door. If an object intervenes in the middle and the sensors do not receive light, a correspondin
