What is automatic door operation?

              Scientists have developed the devices by which a door can be opened or closed automatically. There are three common ways of operating automatic doors: (1) by actuating a pressure pad on the surface in front of the door, (2) by cutting a light beam located in a wall near the door and (3) by actuating a wall mounted manual pressure pad like a switch.

              Automatic doors are powered by various drive systems – some are totally electric, some are electromechanical and others are pneumatic. Various door opening actions are available such as automatic slide with or without manual swing out side panels for use when the automatic doors are locked or turned off; single or double swing doors and side and swing combinations. Automatic door opening and closing devices are becoming more and more popular day by day.
