Sensors used on high speed door

High-speed doors are a common component of various industries, including warehouses, distribution centers, and manufacturing facilities. These doors are designed to open and close quickly, allowing for efficient movement of goods and personnel. To ensure smooth and safe operation, high-speed doors are equipped with different types of sensors, including opening devices and safety devices. These sensors play a crucial role in mitigating risks and maintaining productivity. In this article, we will discuss these sensors in detail.

1. Opening Devices:

Opening devices are sensors that trigger the high-speed door to open when certain conditions are met. The purpose of these devices is to provide ease of access and convenience, while also ensuring the door operates efficiently. Some common opening devices include:

a. Motion Sensors - These sensors detect movement in front of the door. When someone approaches, the sensor sends a signal to the door's control system, prompting it to open. Motion sensors are often used in areas where frequent access is required, such as busy entryways or loading docks.

b. Remote Controls - High-speed doors can be equipped with remote control systems, allowing users to open the door from a distance. This is especially useful in situations where immediate access is needed, without having to physically approach the door.

c. Push Buttons - Push buttons are simple switches installed near the door. When pressed, they send a signal to the control system to open the door. Push buttons are typically installed at predetermined locations for convenient operation.

2. Safety Devices:

Safety devices are critical components of high-speed doors, ensuring the protection of individuals and property during door operation. These devices are designed to detect potential hazards or obstructions, preventing accidents and damage. Here are some commonly used safety devices:

a. Photoelectric Sensors - Also known as presence sensors, photoelectric sensors emit an invisible beam of light across the door's opening. When an object or person obstructs the beam, it interrupts the sensor's signal, causing the door to immediately stop or reverse its motion. Photoelectric sensors are effective in preventing collisions and accidents.

b. Safety Edges - Safety edges are pressure-sensitive strips installed at the bottom or edges of the door. When the door comes into contact with an object, the pressure exerted on the safety edge activates a switch, triggering the door to stop or reverse. Safety edges are particularly useful in preventing injuries and damage to vehicles or people near the door.

b. Safety Curtains - Safety curtains consist of a series of infrared beams that create an invisible protective curtain. If a person or object breaks the curtain, the door will halt or reverse its movement. Safety curtains are commonly used in areas where large objects or a continuous flow of people pass through.

In conclusion, high-speed doors are equipped with various sensors to ensure safe and efficient operation. Opening devices, such as motion sensors, remote controls, and push buttons, provide easy access and convenient operation. On the other hand, safety devices, including photoelectric sensors, safety edges, and safety curtains, detect potential hazards and obstructions, preventing accidents and damage. By incorporating these sensors, high-speed doors can effectively balance speed, accessibility, and safety in industrial environments.
