AHS/AHM36 SSI ABSOLUTE ENCODERS

FLEXIBLE, SMART, COMPACT

Product description

The AHS/AHM36 SSI absolute encoder product family provides increased exibility due to its mechanical adaptation, electrical connectivity, and SSI 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. The encoders are able to connect to a wide range of controls due to a programming tool that can be used to make individual adjustments

to the structure of the SSI protocol, in addition to adjusting the singleturn/multiturn resolution, the counting direction, and other parameters. Thanks to the large operating temperature range from

–40 °C ... +100 °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.
