Description
AMCI DC25 Absolute Analog Single-turn Rotary Shaft Encoder
Designed as a replacement for potentiometers, this absolute analog rotary shaft encoder is an industry leading member of the DC25 DuraCoder family.
Popular applications include closed loop process control and angular measurement of valves, dampers and sorters.
Available with analog voltage or analog current output, the analog DuraCoder has an output format for any application requiring an absolute analog rotary shaft encoder position sensor.
The analog output DC25 DuraCoder can be selected to produce the full output signal over 360, 180, 90, or 45 degrees. Available analog voltage outputs include 0-5Vdc, 0-10Vdc, or +/-10Vdc. The analog current output versions are 4 to 20mA or 0 to 20mA. Package styles include flange or servo with side or end connector.
