Compact Ethernet absolute encoders represent a significant advancement in industrial automation, offering extreme space savings while delivering high precision and reliability. These devices are particularly ideal for demanding applications such as machine tooling, assembly systems, graphic printing, and packaging machinery, where real-time positioning with minimal cycle time and jitter is essential.

Introducing the Baumer EAL580 EtherCAT Series

The latest addition to this category is the EAL580 EtherCAT series, designed for fast and high-precision applications. With a remarkable 62.5 μs cycle time, these encoders excel in scenarios requiring rapid feedback and accuracy. Their compact design features an installation depth of just 47 mm—making them some of the smallest Ethernet absolute encoders available at 58 mm overall size.

Compliance and Ease of Integration

The EAL580 series adheres to the CANopen standard 4.0 for seamless integration into existing systems. Commissioning is straightforward, especially with control software like TwinCAT. Device addressing operates automatically—saving time during setup. Users can also configure preset values directly via a durable IP67-rated button on the device.

Advanced Communication and Flexibility

The series supports multiple EtherNet protocols including EtherCAT (with FoE firmware updates), PROFINET, and upcoming support for EtherNet/IP. The flexibility in operating modes—Free Run, Synchronous Mode, or Distributed Clocks—allows tailored configurations for various applications.

Beyond Cyclic Data: Enhanced Diagnostics

In addition to standard position and speed data, the EAL580 outputs diagnostic information such as device temperature and operational hours. Features like rotary axis functionality and endless operation simplify machine control logic by reducing complex calculations.

Design Freedom Through Compactness

With no need for angle plugs (which are typically required in larger encoders), users can achieve highly space-efficient designs—saving both physical space and costs associated with additional components. The radial plug outlet supports tighter bending radii, enhancing installation flexibility.

Mounting Options and Drive Integration

The EAL580 stands out as the only compact 58 mm Ethernet encoder offering a hollow shaft design combined with optional A or B-sided clamping rings for easy integration into drive systems. This eliminates unnecessary add-on parts while ensuring smooth operation.

The Bottom Line

If you’re designing machinery that requires high precision, minimal space, and reliable communication—whether through EtherCAT, PROFINET, or soon-to-be available EtherNet/IP—the EAL580 series offers an ideal solution.
