OA-Axis series

Active Infrared Presence Detection Door Sensor

The OPTEX OA-Axis series is the new active infrared door sensor standard for use on automatic sliding doors. The OA-Axis series is developed as a combination sensor for threshold safety and activation.


The OPTEX OA-Axis series utilizes OPTEX's unique active infrared technology, combining activation and safety into one sensor. By using the unique OPTEX presence detection technique the OA-Axis series provides maximum safety around the threshold as well as a large motion detection area for door activation.

Easy adjustment

Installation time can be reduced to a minimum by using easily set switches and adjustments. The sensor can be quickly adjusted for many different applications.


The active infrared presence detection of the OA-Axis series 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 are motionless.

Motion detection

The large detection area provides fast detection for any humans or carts approaching from any angle. The sensor's enhanced pattern depth enables it to detect people and objects farther away and allows the door to open conveniently for them. The presence and motion detection areas can be adjusted independently.


By offering different types of output contacts the OA-Axis series meets the requirements and local standards in many different markets. OA-Axis I: relay output for activation and safety. OA-Axis II: one relay for safety and a second relay for motion/activation.
