Industrial door sensors are devices designed to detect the presence of people and objects moving through doors. They use infrared or ultrasonic sensing technology to detect the presence of moving objects. An advanced automatic industrial door sensor is able to distinguish the direction of movement, allowing the door to open only in a specific direction. Furthermore, these sensors are able to distinguish between people and objects, allowing the door to open only in the presence of a person. These sensors are particularly useful in industrial environments, such as factories and warehouses, where it is important to ensure the safety and protection of personnel. They can also be used in other environments such as airports, railway stations, public buildings and many other places where greater security is required.
