VEX Optical Shaft Encoder (2-pack)

Function: The optical shaft encoder is used to measure both relative position of and rotational distance traveled by a shaft. It works by shining light onto the edge of a disk outfitted with evenly spaced slits around the circumference. As the disk spins, light passes through the slits and is blocked by the opaque spaces between the slits. The encoder then detects how many slits have had light shine through, and in which direction the disk is spinning.

Applications: The optical shaft encoder can be used to track distance traveled, direction of motion, or position of any rotary component, such as a gripper arm.
