The Optex OA-72C active infrared door sensor is specially designed for discreet ceiling installation. It performs well as activation and safety for any type of automatic door, and its large pattern can easily be adjusted to different door configurations.


The first two rows of active infrared provide presence detection, which holds the door open as long as a person or object is in the pattern, even if they stop or pause. The presence detection timer can be set to infinity. Its large detection area can be set very precisely and easy by dipswitches and levers to line up with doors and other sensor patterns, providing maximum safety.

Ceiling-mount installation

The Optex OA-72C is perfect for installation in areas where attractive appearance is important. The sensor can be mounted up to 4m (13 feet) high, making it vandalism-resistant.

Slim design

Discreet ceiling-mount design easily blends with any décor. Equipped with silver recess mount cover.

All conditions

The sensor’s advanced signal processing circuit allows it to operate reliably in many different applications and even harsh weather conditions. The large detection area can be adjusted to customize the pattern for either activation or safety applications on any type of automatic door.


Optex automatic door sensors guarantee premium performance and include a 3-year full replacement warranty.
