AT2-033-0120 Heidenhain ID:1325116-07 Rotary Encoder – Technical Product Overview

The AT2-033-0120 (ID:1325116-07) rotary encoder is a high-precision absolute position sensor engineered for demanding industrial environments. Designed with a solid shaft structure and advanced signal architecture, this encoder delivers reliable, real-time position feedback for applications requiring accuracy, durability, and long operational life.


High-Resolution Absolute Positioning

The AT2-033-0120 encoder provides 120 discrete positions per revolution, enabling precise angular measurement across a full 360° rotation. Its binary (BIN) coded absolute output ensures that each position is uniquely identifiable, eliminating the need for reference runs after power interruptions.

Key signal features include:

  • 1-bit timing pulse (TP1) for synchronization
  • 7-bit absolute position output (binary code)
  • Stable signal transitions for noise-resistant operation

This structure guarantees accurate and repeatable position detection in high-speed and high-load systems.


Robust Mechanical Design

Built for industrial reliability, the encoder features a 10 mm solid shaft, ensuring strong mechanical coupling and resistance to vibration. Its optimized internal structure supports dynamic applications with:

  • Maximum rotational speed: up to 5000 rpm
  • Low starting torque: ≤ 0.02 Nm
  • Permissible shaft load: up to 50 N (radial and axial)
  • Optimized moment of inertia for fast acceleration systems

With a service life of approximately 10,000 hours, the AT2-033-0120 is suitable for continuous operation in automated machinery.


Electrical Specifications and Output

The encoder operates on a DC 24V supply (±5%), making it compatible with standard PLC and CNC control systems. It features:

  • NPN open collector output stage
  • Low current consumption (≤ 60 mA)
  • High-speed switching capability up to 20 kHz
  • Fast response times in the microsecond range

These characteristics ensure reliable signal transmission and seamless system integration.


Industrial-Grade Environmental Protection

The AT2-033-0120 is designed to perform reliably in harsh industrial conditions:

  • Protection class: IP66 (dust-tight and water-resistant)
  • Operating temperature: -10°C to +60°C
  • Storage temperature: -20°C to +80°C
  • Vibration resistance: up to 2000 Hz
  • Shock resistance: up to 1000 m/s²

These features make it suitable for environments with high vibration, moisture, and temperature variations.


Cable and Installation Advantages

The encoder comes with an integrated cable system designed for durability and stable signal transmission:

  • Cable length: 5 meters
  • Cable type: PVC insulated
  • Wire specification: AWG22 / AWG24
  • Shielded design for improved noise immunity

Its compact size and lightweight structure (~0.48 kg) simplify installation in space-constrained systems.


Application Areas

The AT2-033-0120 rotary encoder is widely used in industrial automation systems requiring precise and stable position feedback:

  • CNC turret indexing systems
  • Rotary tables and indexing mechanisms
  • Packaging and processing machines
  • Textile and printing machinery
  • Automated production lines

Its absolute encoding capability ensures uninterrupted position tracking, even after power loss.


Conclusion

The AT2-033-0120 Heidenhain ID:1325116-07 Rotary Encoder is a reliable and high-performance solution for precision motion control applications. Combining absolute position feedback, robust mechanical construction, and industrial-grade protection, it delivers consistent performance in even the most demanding environments.

For engineers and system integrators seeking a durable and accurate rotary encoder, the AT2-033-0120 stands out as a dependable choice for modern automation systems.
