I have the Photo Sensors, but I don't see the part number you are referencing. These are the following numbers: AST13832 on both, EE000509-010533, EE000508-010533. Are these parts you listed compatible with SD5500, SD7500 and SD8500 models compatible with the parts I have?

Those are manufacturer numbers for each sensor. The Hormann EL101 sensors are compatible with all 3 models you listed.

Did you find what you were looking for?
