Product Description:

The AI2512131292G absolute rotary encoder is built by Danaher as part of the Dynapar Encoders series. Designed for servo axes and conveyor drives, it translates shaft angle into serial data so motion controllers can maintain position, velocity, and direction without accumulating errors. Because the encoder provides both single-turn and multi-turn tracking, it removes the need for homing after power cycles and supports uninterrupted operation in automated assembly lines and packaging machines.

The sensing performance includes an absolute accuracy of ±0.01°, repeatability of ±0.002°, and linearity within ±1/2 LSB, which limit the permissible deviation between the reported and actual shaft angles. For dynamic applications, the encoder can run continuously at 10,000 rpm and withstand peak speeds of up to 12,000 rpm. A clamping mount secures the housing, while the shaft accepts axial loads of up to 40 N without affecting measurement. The enclosure has an IP64 protection rating, allowing it to resist dust ingress and splashing liquids when installed in standard machinery. Position data are delivered over the DeviceNet bus in binary format, allowing direct connection to PLC networks with minimal wiring.

Installation depth is limited by a rear length of 71.3 mm, and the 10 mm solid shaft accommodates standard couplings. The encoder electronics draw 250 mA, which should be reserved in the DeviceNet segment power budget. Feedback granularity reaches a single-turn resolution of 13 bits and a multi-turn resolution of 12 bits, enabling controllers to detect fine movements and monitor up to 4,096 revolutions. The radial bearing capacity is rated at 60 N, supporting belt-driven or gear-coupled loads that introduce side forces while maintaining measurement accuracy. The solid shaft provides a direct mechanical interface for couplings used on conveyor drives, servo axes, and other rotating equipment.
