This 200 pulse per rotation single-output encoder outputs electrical pulses which you can interpret using a microcontroller to find the position of the input shaft. This allows you to add feedback to motor control systems. Encoders of this kind are often used in balancing robots and dead reckoning navigation. The encoder comes with a set screw coupler which will attach to any 4mm shaft.

Output stage was floating, pulses didn't return to zero,
It works great except you can't tell if its going CW or CCW because it only has one data output! Useless! I can't even think of a application that doesn't need to know what direction it's going in. SparkFun can you please list this on the site so nobody makes the same mistake as me.
Sorry about that! We do state that it has a single output in the description though. COM-10932 is the dual output version of this encoder and can tell you what direction it's turning.
