SICK ANS/ANM58 PROFINET Absolute Encoders: Precision & Reliability for Industrial Motion Control

In today’s fast‑evolving industrial automation landscape, production equipment demands higher precision, faster response, and stronger environmental adaptability than ever before. As a core sensor for capturing motion control data, encoders directly determine the efficiency, stability, and quality of entire production lines. To address these challenges, SICK has launched the ANS/ANM58 PROFINET absolute encoders—a robust solution built for real‑time, high‑precision motion monitoring and process control across demanding industries.

Key Features of SICK ANS/ANM58 Encoders

These encoders integrate mature industrial Ethernet technology and high‑performance sensing mechanisms, delivering standout capabilities:

• PROFINET with IRT (Isochronous Real‑Time) communication: Enables microsecond‑level synchronization and deterministic data exchange for multi‑axis systems.

• High‑resolution optical measurement: 18‑bit single‑turn resolution + 16‑bit mechanical multi‑turn resolution for absolute position feedback.

• Mechanical multi‑turn technology: Gear‑based position counting—no battery, no signal drift, no position loss after power cycles.

• Heavy‑duty mechanical design: Withstands up to 200G shock acceleration; robust die‑cast zinc housing with copper‑nickel coating for corrosion and EMI resistance.

• Wide temperature range: Operates reliably from –40 °C to +85 °C, suitable for harsh industrial environments.

• Long service life: Bearing life rated at 30 × 10⁹ revolutions, supporting 24/7 continuous operation.

Real‑World Application Success Stories

1. Machine Tools: Multi‑Axis Punch Presses

Multi‑axis synchronized punches require precise coordination of multiple slides to ensure accurate stamping and consistent product quality.

Challenges

• High shock and vibration during operation

• Strict multi‑axis synchronization requirements

• Strong electromagnetic interference from frequent motor starts/stops

Benefits with ANS/ANM58

• 200G shock resistance eliminates signal skipping or data loss

• IRT ensures simultaneous, microsecond‑level data updates for perfect axis synchronization

• One‑piece metal center bracket provides rigidity and stability under heavy loads

2. Crane & Hoisting Systems

Overhead cranes and trolley mechanisms rely on accurate position feedback for safe, efficient material handling across large workspaces.

Challenges

• Inaccurate counting or position loss with Wiegand or battery‑backed multi‑turn encoders

• Signal distortion and positioning errors caused by electromagnetic interference over long travel distances

Benefits with ANS/ANM58

• Purely mechanical multi‑turn gear train records every absolute position without power

• Die‑cast zinc + copper‑nickel alloy housing delivers superior EMI shielding and corrosion resistance

• Stable, interference‑free communication even in harsh industrial environments

3. Glass Manufacturing: Edge Pulling Machines

Glass edge pullers operate continuously in high‑temperature, dusty conditions, requiring precise speed, position, and tension control to produce uniform glass sheets.

Challenges

• Ultra‑high multi‑axis synchronization for 12 sets of pull rollers

• 7/24 operation in high‑temperature, dusty environments

• EMI and data packet loss in dense motor setups

Benefits with ANS/ANM58

• IRT synchronization ensures coordinated motion across all pull rollers

• Wide temperature tolerance and long bearing life reduce maintenance

• Integrated metal bracket acts as a shield against electromagnetic interference, stabilizing data transmission

Conclusion

The SICK ANS/ANM58 PROFINET absolute encoders combine industrial‑grade robustness, high precision, and real‑time synchronization to solve critical challenges in machine tools, cranes, glass machinery, and beyond. With reliable absolute position feedback, strong anti‑interference performance, and exceptional durability, these encoders help manufacturers improve accuracy, productivity, and uptime in modern automated production lines.
