I recently ran across the 32060 Technic Gear Timing Wheel 8 Tooth element when sorting a mixed bag of parts.

This element doesn't appear in many sets as a functional element. Here's one example from the Barcode-Multi-Set (8479) set:

Instruction step

What is the purpose of this element, and how does it work? I'm guessing from the name that it has something to do with timing. Perhaps it is used as a rotary encoder somehow?

When looking at Blakbird's Technicopedia page for this Technic set, this part is indeed used as a rotary encoder in combination with the bar code scanner.

See the last entry on the page.

    That makes sense. Thanks! I didn't realize that the barcode scanner in that set could be used to read speed that way.
