Product Details

The OPTEX OM-104C microwave sensor has been specially designed to increase comfort on opening all types of automatic doors.
Due to its compact design and easy installation, the OM-104C fits on every header in any application.



The OPTEX OM-104C features highly protective (airtight) housing that stops insects, dust, and water drops from entering the sensor. The OPTEX OM-104C prevents damage caused by static electricity. The window made from impact-resistant plastic protects against vandalism.

Easy Installation

The OPTEX OM-104 will suit almost any installation site, with no complicated adjustment required. With the closest angle setting to the door (default setting), the detection area has no overlap with the door, causing no malfunction. (Only when sensitivity is set to middle and the installation height is below 2.7 m.)

Easy Adjustment

By removing the stopper, the detection area can be set closer to the door for sites where enhanced safety is required.
