Automatic doors, while offering convenience, pose risks when they are not adequately equipped with safety mechanisms. That's where Safescan's technology steps in—offering precision detection, collision avoidance, and safety compliance to meet both the functional and regulatory demands of modern architectural environments. This article explores the features, benefits, applications, and technological innovations of Safescan laser safety sensors for automatic swing doors.

1. Introduction to Automatic Swing Doors

Automatic swing doors are designed to open and close automatically when triggered by a sensor, button, or remote system. They provide easy access for users, particularly in high-traffic areas or buildings where accessibility is critical. However, without safety precautions, these doors could potentially cause injury or damage, particularly in scenarios where someone may not anticipate the door’s movement.

Swing doors operate differently compared to sliding or revolving doors, as their motion requires more space and presents the risk of collision in both the swing and pinch zones. Therefore, safety systems such as Safescan laser sensors are essential to minimize risks by detecting obstructions and stopping or adjusting door movement accordingly.

2. The Role of Safety Sensors in Automatic Swing Doors

Safety sensors are the core of a well-functioning automatic swing door system. They ensure that the door operates smoothly while protecting users from harm. Safescan laser safety sensors are a type of active infrared sensor that uses laser technology to detect the presence of objects or people in the path of the door. These sensors create an invisible laser field that continuously monitors the area, preventing the door from closing if it detects any obstructions.

The Safescan sensor not only enhances safety but also ensures regulatory compliance with door safety standards, such as those outlined in EN 16005 and ANSI/BHMA A156.10. These standards mandate the use of sensors to ensure that doors do not close when someone is in the detection zone, which can cause injury or accidents.

3. How Laser Sensors Work: Time-of-Flight Technology

Safescan laser sensors typically employ time-of-flight (TOF) technology. TOF measures the time taken for a laser beam to be emitted from the sensor, reflect off an object, and return to the sensor. Based on the time measured, the sensor can accurately determine the distance and size of an object within the detection zone. This precise detection allows the system to recognize even small objects, such as hands or strollers, within the door’s path.

This technology offers a significant advantage over traditional motion or presence sensors, which may not provide the same level of accuracy or fail to detect smaller objects or obstructions in tight areas such as door hinges or the pinch zone.

4. Key Features of Safescan Laser Safety Sensors

Below are some of the essential features that make Safescan sensors an optimal choice for automatic swing doors:
