The Optex OM-105C and 106C microwave sensors are especially designed to increase the comfort on opening all types of automatic doors. The Optex microwaves provide fast detection for all automatic door installations and particularly for applications with high-speed entries. Due to the industrial design and easy installation these sensors will fit on every header or ceiling in any application you can imagine.

Detection area

The Optex microwave range offers a narrow or wide detection area that makes it suitable for all types of installations. The narrow setting is easy to set by just clicking the narrow lens on to the radar module. By turning the module left or right and tilting it up and down the microwave can be adjusted quick and simple for many different applications. No external set-up device is needed.

Swing door activation

When installed above the pivot the Optex OM-106C will ignore the door movement of a swing door. Therefore it is ideal to install as swing door activation sensor.

Auto-Caution mode

The Auto-Caution Mode guarantees more reliability to prevent the door from closing, even if a person is wavering in the detection area. The sensor will immediately change from uni directional to multi directional for safety purposes. This function is only available on the OM-106C.

Uni-directional setting

The OM-106C is equipped with a dipswitch for uni directional or bi directional mode. By selecting the uni directional mode the sensor will only detect traffic approaching the door, allowing the door to close more quickly for departing traffic. Fast closing of doors offers a large benefit for the end user, because the doors will stay open for a limited time and therefore they will contribute to saving energy.


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