Active Infrared Sensor for Industrial Doors

The OPTEX OA-6500S for industrial doors is an Active Infrared sensor combining activation and safety in one sensor.


The OPTEX OA-6500S uses active infrared technology to combine activation and safety in one sensor. By using the unique OPTEX presence detection technique, the OA-6500S provides both maximum safety around the threshold of an industrial door and an extra large motion detection area, even at mounting heights up to 6.5 meters.

Suitable for Industrial Applications

The OPTEX OA-6500S is optimized for industrial doors. The 1st row has a door cancel function that reduces malfunctions caused by door movement. Also, the activation and safety outputs can be selected from N.C. and N.O. simply by selecting the dipswitches. And the automatic infinite presence detection increases safety and avoid unwanted door opening due to sudden change in floor condition.

Motion Detection

The large detection area provides fast detection for any traffic, including trucks, approaching from any angle. The sensor’s enhanced pattern depth enables it to detect objects farther away and allows the door to open conveniently. The presence and motion detection areas can be adjusted independently.

Easy Adjustment

Installation time can be reduced to a minimum by using easily set switches and trimmers so that the sensor can be quickly adjusted for many different applications. To adjust the presence detection area, the use of an OPTEX Infrared finder is recommended.
