AHS/AHM36 CANopen ABSOLUTE ENCODERS

FLEXIBLE, SMART, COMPACT

Product description

The AHS/AHM36 CANopen absolute encoder product family provides increased exibility and diagnostics due to its mechanical adaptation, electrical connectivity, and CANopen communication. With their rotating male connector or cable outlets as well as the various mounting

hole patterns and adapter anges, these

encoders are suitable for nearly any application. Individual adjustments can be made to the singleturn/multiturn resolution, the counting direction, and other parameters when integrating the encod-

ers into the CANopen network. The encoder also communicates diagnostic data such as temperature or operating time. Thanks to the large operating tem-

perature range from –40 °C ... +85 °C

and the protection class up to IP67, this encoder family can be used in harsh ambient conditions. The rugged, reliable, fully magnetic sensor system provides a maximum resolution of 14 bits for the singleturn variant and 26 bits for the multiturn variant.

UL 508 compliant.
