What are the types of automatic door safety sensors?

Automatic door sensor refers to a type of device that can detect objects in front of a door and drive the door to automatically open or close. The automatic door sensor mainly senses the presence of people or objects through the sensor and transmits the signal to the door controller. The door controller controls the opening and closing of the door by the motor based on the signal. The automatic door sensor can achieve contactless entry and exit, greatly facilitating people's travel and entry. The common automatic door sensors mainly include infrared sensors, ultrasonic sensors, microwave radar sensors, laser sensors, loop detector sensor .etc.

1.Infrared sensors
The infrared sensor emits infrared light, When someone or an object enters the detection area and is reflected by the infrared light, it can determine whether there is an object present before going out, thereby driving the door to open or close.
2.Ultrasonic sensors
Ultrasonic sensors emit a certain frequency of sound waves. When the sound waves encounter an object in front of the door and reflect back, they can determine whether there is an object present before going out, and then open or close the door

Application

How to achieve automatic sliding door anti-pinch function?

For automatic sliding doors, electric glass doors, automatic aluminum doors, or automatic frameless glass door systems, installing anti-pinch through beam photo eyes is an effective safety solution. The infrared signal emitted by the eyes on one side of the door frame reaches the receiver eyes on the other side, which will establish a straight light path. As long as the ray path is obstructed by children, pets, disabled individuals, or anyone standing in the passage, the safety beam sensor or light barrier will immediately detect the obstacle and prevent the door from closing, thereby preventing people or objects in the middle from entering and clamping. Due to the structural characteristics of automatic sliding doors, generally, mini type opposed sensors are a common choice.

Safety sensor solutions for wing gates:

Smart wing gates are often used to record traffic data in public places such as subway stations with heavy traffic. The gates installed in public transportation places pay more attention to the stability and safety protection functions of the products because of the high traffic flow. The combination of gate and ticket charging system tests the anti-intrusion and anti-following detection function of photoelectric sensor. The PT12T micro photoelectric sensor adopts the principle of through-beam photoelectric induction, stable and reliable performance, convenient and quick installation method, which makes it very popular among intelligent wing brake customers. PM18T adopts metal housing design, stable performance, collision resistance and corrosion resistance. Intelligent wing barrier optical turnstile products suitable for outdoor scenes.
