AI2512141C92F by Danaher

The Danaher AI2512141C92F encoder delivers robust absolute position measurements as part of the Dynapar Encoders series, designed for high-precision industrial automation. This multi-turn optical encoder integrates a Profibus-DP interface conforming to the Encoder Profile, enabling seamless communication in distributed control systems. The device accepts a wide Power Supply of 10–30 VDC, ensuring compatibility with standard industrial power rails and offering short-circuit protected 60 mA per bit outputs. Its binary output code provides direct digital position feedback with a combined resolution of 12-bit multi-turn plus 10–14 bit single-turn, effectively delivering up to 24 bits of position data. Encased in an enclosure rated IP64 or IP67, the AI2512141C92F withstands harsh environments while maintaining reliable signal integrity.

The AI2512141C92F exhibits precise mechanical performance with Absolute Accuracy of ±0.01° mechanical (36 arc-sec) and Repeatability of ±0.002° mechanical (7.2 arc-sec). It can operate across a broad Operating Temperature range of –40 °C to +85 °C and survive in Storage Temperatures from –40 °C to +100 °C, while supporting up to 75% non-condensing Humidity. High-speed applications benefit from its Max Shaft Speed of 10,000 RPM continuous (12,000 RPM peak). The encoder’s Shock Resistance of 1,000 m/s² for 6 ms and Vibration Resistance of 100 m/s² (10–2,000 Hz) ensure mechanical robustness, and its noise immunity meets EN61326-1 compliant standards. Electrical input is managed efficiently, drawing Current Consumption of 220 mA in single-turn mode and 250 mA in multi-turn mode.

Operational features include a Frequency Response range from Auto 9.6 kBaud to 12 MBaud over its Profibus-DP link, supporting data rates up to 12 Mbit/s. The encoder tolerates radial and axial loading up to 13 lb radial and 9 lb axial on 10 mm shafts, and 24 lb radial and 13 lb axial on 6 mm shafts, ensuring reliable coupling to rotating machinery. Alarm and warning bits monitor LED current thresholds and temperature limits, enabling proactive status diagnostics. The device supports cable lengths up to 400 m at 500 kHz signaling speed, safeguarding communication integrity in distributed installations.

Integration into control architectures is streamlined by its binary output, eliminating the need for additional signal conversion. Compatibility with standard Profibus-DP masters and existing Danaher drive systems reduces engineering complexity. The AI2512141C92F’s combination of high resolution, rugged environmental ratings, and wide input voltage range makes it suitable for robotics, material handling, CNC machines, and other industrial automation applications requiring precise, reliable feedback.
