1, automatic door opening signal is the contact signal, microwave radar and infrared sensor is commonly used in two kinds of signal sources:
Microwave radar is the displacement of the object response, and thus the reaction speed, suitable for people walking through the normal speed of the place, it is characterized that once the door near the staff do not want to go out and still do not move, the radar will no longer react, automatic The door will be closed, the door machine has a certain protective effect.
Infrared sensors react to the presence of objects, regardless of whether the person moves or not, as long as it is within the scanning range of the sensor, it will react to the outgoing contact signal. The disadvantage is that the infrared sensor response speed is slow, suitable for people with slow access to the place.
2, the key switch can be a touch-type button, more convenient is the so-called elbow switch. The elbow switch is very durable, especially if it can be operated with an elbow. Avoid contact with the hand.
3, foot switch, function the same, but the higher requirements of the waterproof, and the foot of the great force, easy to foot switch failure. There is also a handle with a contact switch, when the handle is pushed (or in the opposite direction of the pull) in place, the door to provide contact signal.
4, the timer can automatically control the state of the door, the principle is to connect the clock with a specific switch circuit can be preset time will automatically open the door or lock the door state.
The system configuration of the automatic door refers to the peripheral auxiliary control device, such as the door opening signal, the access control system, the safety device, the centralized control and the like, which are equipped with the automatic door controller according to the requirement of use. Must be based on the characteristics of the use of the building. Through the composition of the staff, building automation system requirements and other reasonable with auxiliary control device. 1, open the door signal is also called contact signal, microwave radar and infrared sensor is commonly used in two kinds of signal source; 2, key switch; 3, foot switch; 4, timer.
220-volt two-way wireless remote control receiver controller, can control the equipment to reach the motor is positive and negative; or switch on and off conversion and a variety of special control procedures. Mainly used in electric doors, windows, lifting equipment, gates, lifts, industrial control and security industries and other fields.

3. With a buzzer instructions to facilitate the determination of the switch working status.
On the Puda good. I recently went to them to buy several times, many varieties, good service. The price is not expensive. You can ask the next reference
