ACTIVE INFRARED SENSOR
The OPTEX OA-4500 is based on active infrared technique, combining activation and safety into one sensor. By using the unique OPTEX presence detection technique the OA-4500 series provides maximum safety around the threshold of an industrial door and offers, at the same time, a large motion detection area for door activation.
The active infrared presence detection of the OA-4500 can be set very accurately and can be moved 6° towards or away from the door. The sensor detects a person or object and holds the door open as long as they are in or near the threshold area, even if they stop or pause.
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 area’s can be adjusted independently.
Installation time can be reduced to a minimum by using easily set switches and trimmers, therefore 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.
