ETC 120EN-128-C24

Model
120E
Optical Encoder
The model 120E is a light-duty optical encoder
that can be manually or motor operated. This
unique device outputs two square waves at a
maximun rate of 128 pulses in quadrature with
other resolutions as low as 10 pulses available.
Typical applications includes Motion sensing and
control, Motor control, Flow control, Low-to-high
input for test and measurement, Medical
instrumentation, Robotics and Computer
Peripherals.
