Optical Sensor OS1 what does this plug into?

[Jyetman]

There is no information on APEX website or the websites that sell them. Why isn't there more info on this sensor like if it requires a module or if it plugs directly to the apex brain?

This is what I found under the FMM accessories

Fifth product down is the OS-1
