Parallax Incremental Rotary Encoder

I've found an awesome rotary encoder (I believe it was the smallest on Rootshop) but I have no idea how to use it? I believe there's an input, a ground and a signal pin, but I don't know how to configure it or anything. I'm going to be using it with an arduino.

I've digged the web and have found no documentation. Just sayin

Thanks ;)

That is a "quad encoder"

This is probably a “quad encoder” and should include a common pin, and one pin for each of the (2) sensors inside. Do some searching for quad encoder and you can see how they work and how the 2 sensors inside relate to eachother. For simplicity, I would put a continuity tester between a couple pins and see if you get a series of HIGH/LOWS as you rotate the shaft. You should be able to figure out at least which pin is what this way.
