Model 120E
Vishay Spectrol
The Model 120E is a light-duty optical encoder that can be manually. This unique device outputs two square waves at a maximum
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.
