The Hörmann D437119 Photo Eye Shield is an OEM protective cover designed for Hörmann photoelectric safety sensors used on powered doors. By shading the sensor lens from direct sunlight and guarding it from dust, wash-down spray, and incidental contact, the shield helps maintain reliable beam alignment and consistent obstruction detection. It’s a practical replacement part for missing or damaged shields on commercial and industrial door systems, including high-performance and sectional/rolling door applications where Hörmann photo eyes are specified.
This shield mounts over the existing photo eye on the standard sensor bracket with no electrical connections or programming required. After installation, verify alignment and test the door’s safety reversal per the operator manual and applicable codes. Keep the beam path clear and clean the sensor lens as part of routine maintenance. For compatibility, match part number D437119 to the parts list of your specific Hörmann operator or door model.
