A sensor door is an automatic door system that detects users with a sensor, opens its leaves with a motor and closes on its own once the passage is complete. Choosing the right system depends on the entrance’s traffic, the expected safety level and the building’s architecture.
1. Traffic density
The number of daily passages determines motor power, mechanism durability and maintenance intervals. Busy entrances such as hospitals, malls and airports call for an industrial-grade system rated for continuous operation. Standard-grade systems are usually enough for offices and shops.
2. Sensor type
- Radar (microwave) sensor: detects movement and covers wide areas.
- Active infrared sensor: detects presence and notices someone standing in the leaf path.
- Combined sensor: combines opening and safety functions in one unit.
In addition to the activation sensor, safety sensors monitoring the leaf path prevent the door from closing on a person or object.
3. Glass and profile
Laminated safety glass (for example 4+4) keeps fragments together if it breaks. Glass thickness, profile colour and indoor/outdoor use should be evaluated together with the architecture.
4. Energy efficiency
Controlled, fast closing reduces heat loss from conditioned interiors. For busy, windy entrances a revolving door or a double-door vestibule is also worth considering.
5. Integration
If card access, night locking, fire scenarios and building automation are defined up front, cabling and control board selection can be planned accordingly.
6. Service access
Fast access to spare parts and service after installation is as important as the product itself. Periodic maintenance covers sensor adjustment, belt tension and track cleaning.
