type DP21 series
The DP21 may be used as a
manual input device for
digitally controlled equipment
such as CAD/CAM systems,
electronic test equipment,
medical electronics,
instrumentation, computer
peripherals and machine tools.
Typically, the encoder drives an
up/down counter and it is used
to control one or more
functions. Common
applications include motor
speed control, cursor control,
frequency setting, amplifier
gain adjustment and table
positioning.
