AI25001321127 by Danaher

The Danaher AI25001321127 encoder, part of the Dynapar Encoders series, is a high-precision absolute optical encoder engineered for rugged industrial automation applications. It delivers 13-bit single-turn resolution and 12-bit multi-turn resolution for consistent motion feedback across all operating cycles. The device supports an input power range of 10–30 VDC, enabling compatibility with varied voltage systems in factory environments. Its IP64 protection rating ensures resistance to dust ingress and water splashes, extending service life under challenging conditions. Manufactured with an aluminum housing and stainless steel shaft, it combines durability with precise optical sensing technology for reliable performance.

In terms of critical specifications, the AI25001321127 offers an absolute accuracy of ±0.01° mechanical (36 arc-sec.) and repeatability of ±0.002° mechanical (7.2 arc-sec.), ensuring tight positional control. The encoder’s frequency response (baud rate) auto-adjusts between 9.6 Kbaud and 12 MBaud to match host communication capabilities. It consumes 220 mA in single-turn mode and 250 mA in multi-turn mode, while maintaining peak shaft speeds of 10,000 RPM continuous and 12,000 RPM peak. The device operates reliably across an ambient temperature range of –40 °C to +85 °C and can be stored from –40 °C to +100 °C. The integrated glass code disc and optical interface yield a high signal-to-noise ratio, and the Profibus-DP Encoder Profile interface ensures seamless network communication.

Operationally, the encoder’s absolute, optical design eliminates homing procedures, reducing system downtime after power cycles. Its automatic baud-rate detection enables smooth synchronization with controllers without manual configuration. The robust aluminum housing and stainless steel shaft withstand mechanical stresses, while the glass code disc preserves high resolution and repeatability over millions of revolutions. Intrinsic current consumption remains stable across the operating temperature span, and the IP64 sealing prevents contamination of the optical path. The unit’s compact form factor and standard shaft diameter specification simplify retrofit into existing machinery.

System integration is facilitated by compatibility with standard Profibus-DP networks and encoder profiles, enabling plug-and-play connectivity with PLCs and motion controllers. The encoder’s universal input power requirements and auto-configuring interface reduce wiring complexity in conveyor systems, robotics, and process control equipment. Its robust environmental ratings and precise feedback characteristics make it ideal for semiconductor manufacturing, packaging machinery, and CNC tool applications. The AI25001321127 joins the Danaher portfolio of Dynapar Encoders to deliver dependable, real-time position data for advanced industrial automation platforms.
