Shaft Encoders Overview

The Quadrature Shaft Encoder detects the rotation of an axle that passes through

it. It has a resolution of 360 counts per revolution (2 count intervals), and can

distinguish between clockwise and counterclockwise rotation.

The Quadrature Shaft Encoder is an upgrade from the original Shaft Encoder. The original version

contains only one internal sensor, which detects the slits in an internal disc as it spins, giving it a

resolution of 90 counts per revolution. Only one output channel (wire) is needed to transmit the

sensor data to the Vex Microcontroller.

The upgraded Quadrature

Shaft Encoder includes

a second optical sensor

which allows the sensor

to detect if the internal

disk is spinning clockwise

or counterclockwise and

increases the resolution to

360 counts per revolution

(2 count intervals). Two

output channels (wires)

are needed to transmit its

sensor data to the Vex.

Original Shaft Encoder

Only has one output wire.

Quadrature Shaft Encoder

Has two output wires.
