Quality Easy Adjustment Presence Detection
Flexible Concealed
SafetyCeiling mounted
The OPTEX OA-72C Active Infrared Sensor is
a ceiling-mount type sensor for automatic
doors. Its stylish design and flexible detection
area setting fit to any existing entrance.
Reliable
Safe and Stable Operation
The OPTEX OA-72C has the ability to detect the pres-
ence of a person or object within its field of view, thus
keeping the door open anytime someone is near. The
presence timer can be adjusted for 2, 30 or 60 seconds.
In addition, snow mode is built-in to add stability in
locations where the sensor is exposed to harsh environments.
Flexible Detection Area
Adjust the detection area Left and Right and move it
closer or farther away from the door. Adjustment is accomplished by the movement of independent threshold and approach areas. Fine adjusters allow for adjustment within 1 inch of the moving face of the door.
High Mount Capability
High ceilings are not a problem for the OA-72C. The
sensor can be mounted as high as 13 feet above the
floor.
