    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.

    Heavy-Duty Reliability

    AMCI's DuraCoder rotary shaft encoders are resolver-based, providing the heaviest duty 2.5" rotary shaft encoder available, anywhere. Several features set this family of rotary encoders apart from the competition; namely, its cost saving durability, field programmability, and wide range of applications.

    •     Cost-saving durability
    •     Resolver-based reliability
    •     Field programmable output resolution
    •     Wide range of applications
    •     More...

    AMCI resolver-based rotary shaft encoders have earned a "bulletproof" reputation among established machine builders and successful system integrators.

    The AMCI DuraCoder product line boasts up to an IP67 rating. Solid shaft and hub shaft versions are available, and both types incorporate an oversized double row bearing that supports shaft loads up to 100 lbs. radial / 50 lbs. axial.
