Shaft Encoders 2001
I
Incremental encoders are sensors capable of
generating signals
in response to rotary movement. In conjunction with mechanical
conversion devices, such as rack-and-pinions, measuring wheels or
spindles, incremental shaft encoders can also be used to measure
linear movement.
The shaft encoder generates a signal for each
incremental change in position.
With the
optical transformation,
a line-coded disc made of metal,
plastic or glass and positioned on a rotary bearing interrupts the infra
red light ray emitted by gallium arsenid sender diode. The number of
lines determines the resolution, i.e. the measuring points within
a revolution. The interruptions of the light ray are sensed by the
receptor element and electronically processed. The information is then
made available as a rectangular signal at the encoder output.
