How do motion sensor doors work?

What sensors are used in sliding doors?

Sensors can be used to detect obstacles in the path of closing doors. The simplest sensor consists of a light beam aimed across the opening: when the beam is broken by an obstacle, the operator prevents the door from closing. Infrared and radar safety sensors are also commonly used.

Do automatic doors use magnets?

Automatic Magnetic Door. – The new mechanism for automatic door which is driven from the attraction between magnet and coil. – Quiet and smooth opening and closing.

How are automatic doors powered?

Automatic door openers use electricity to power a motor inside the unit to open the doors. The auto opener is often referred to as an auto operator or low energy operator (read this previous blog post on the basics of auto operators). Low energy refers to the speed and force of the door opening swing.
