AI2512123X32X14 by Danaher

The Danaher AI2512123X32X14 absolute encoder is part of the Dynapar Encoders series, engineered to deliver high-precision position feedback in industrial automation environments. It provides an exceptional absolute accuracy of B110.01B0 mechanical (36 arcsec), coupled with adjustable single-turn resolution of 10–14 bits and a fixed multi-turn resolution of 12 bits. Powered by a 10–30 VDC input, the encoder maintains reliable performance across a wide supply range, while its Profibus-DP interface ensures seamless integration into fieldbus networks. Designed for rigorous industrial applications, the AI2512123X32X14 encoder supports both IP64 and IP67 enclosure ratings to defend against dust ingress and water immersion.

Technical specifications of the AI2512123X32X14 highlight its robust engineering: it meets a repeatability of B10.002B0 mechanical (7.2 arcsec) and operates with a maximum shaft speed of 10,000 RPM continuous (12,000 RPM peak). Data exchange occurs over a Profibus-DP link at an auto-selecting baud rate from 9.6 kBaud to 12 MBaud. Current consumption is optimized at 220 mA for single-turn and 250 mA for multi-turn units, while starting torque remains low, under 1.4 in-oz, reducing load on drive systems. The device offers multiple shaft diameter options—6 mm, 10 mm, 3/8 in to suit Servo Mount, Clamping Mount, and Square Flange Mount configurations.

Operational reliability is ensured by an extended temperature range of –40 °C to +85 °C operating and –40 °C to +100 °C storage, enabling use in harsh industrial climates. The encoder’s lightweight design, at approximately 350 g (single-turn) or 400 g (multi-turn), minimizes inertia and supports rapid acceleration profiles. Its absolute measurement principle eliminates the need for homing routines after power cycles, enhancing system uptime. The robust enclosure and low starting torque enable stable performance in automated conveyors, CNC machinery, and robotic joints.

System integration is streamlined through the Profibus-DP encoder profile, which provides real-time position updates and simplified device parameterization. The AI2512123X32X14 is ideally suited for precision motion control, packaging machines, and assembly lines where high reliability and accuracy are critical. With its combination of part_number, manufacturer, and series identifiers, this encoder meets demanding specifications for industrial automation OEMs and system integrators alike.
