CA26 Absolute Magnetic Grid Encoder for Long Stroke Motion

What Makes CA26 Different from Traditional Incremental Encoders

Traditional incremental encoders calculate position by tracking the number of pulses generated during motion. In the event of a power interruption, the system may lose its position reference and require a homing procedure before normal operation can resume.

The CA26 absolute magnetic grid encoder uses absolute position feedback to provide the current position directly to the control system. This allows the equipment to restart without returning to a reference point, simplifying the recovery process and improving motion continuity.

How CA26 Absolute Magnetic Grid Technology Supports Long Stroke Motion

Maintaining accurate position feedback becomes more challenging as motion systems extend to longer travel distances. Factors such as mechanical tolerance, thermal expansion, and installation deviation can gradually influence positioning consistency, especially in precision automation equipment.

The CA26 absolute magnetic grid encoder integrates absolute position detection with magnetic grid technology to deliver reliable measurement across long-stroke applications. With an effective measurement length of up to 8m, it enables continuous position tracking for systems where travel distance and feedback reliability are critical considerations.

Beyond its long measurement range, the magnetic grid structure is designed for industrial environments where dust, vibration, and other operating conditions may affect measurement performance. Together with 1.0μm resolution, CA26 offers a practical feedback solution for precision motion systems requiring stable and repeatable positioning.

CA26 Performance Parameters for Reliable Motion Feedback

For precision motion systems, encoder selection involves more than resolution alone. Accuracy, repeatability, response speed, and communication compatibility all influence how effectively the feedback system performs in real applications.

The key specifications of the CA26 absolute magnetic grid encoder include:

The ±5μm/m positioning accuracy and ±2.5μm repeatability help the system maintain consistent positioning results during repeated motion cycles. Meanwhile, the response speed of up to 5m/s supports applications where fast movement and accurate feedback need to work together.

With BiSS-C communication, CA26 can be integrated into motion control architectures that require stable data transmission and precise position feedback.

Why CA26 Fits Continuous Production Equipment

In continuous manufacturing environments, motion systems are expected to deliver consistent performance over long operating periods. Beyond basic positioning accuracy, equipment engineers also need to consider factors such as position recovery after interruption, motion repeatability, and feedback stability during frequent cycles. The CA26 absolute magnetic grid encoder is developed for automation systems where reliable position information is essential for maintaining production consistency.

1.Display Panel Equipment

Display manufacturing equipment often involves large work areas and extended axis travel for processes such as panel transfer, alignment, and inspection. As travel distances increase, maintaining accurate position control across the entire working range becomes more demanding. With an effective measurement length of up to 8m, CA26 helps support large-format motion platforms that require consistent position detection throughout repeated production movements.

2.SMT Equipment

SMT machines perform rapid and repetitive movements during component placement, where response time and motion consistency directly influence throughput and process stability. The CA26 supports high-speed applications with a response speed of up to 5m/s, while its absolute position detection helps the system quickly recover the current position when restarting after an interruption.

3.Precision Inspection Equipment

For inspection equipment, positioning accuracy directly affects measurement reliability. Small deviations in axis movement can influence inspection results, especially in applications requiring repeated measurements at precise locations. With ±5μm/m positioning accuracy and ±2.5μm repeatability, CA26 provides consistent motion feedback for inspection systems that depend on repeatable positioning performance.

4.Dispensing Equipment

Dispensing processes require accurate path control to ensure uniform material application across different workpieces. Variations in motion positioning may affect dispensing consistency and product quality. By combining absolute measurement capability with magnetic grid technology, CA26 supports precise and repeatable movement control for automated dispensing systems.

How to Select the Right Absolute Magnetic Grid Encoder

Choosing an absolute magnetic grid encoder depends on how the encoder will be used within the entire motion system. Beyond basic specifications, factors such as machine operation, travel range, accuracy requirements, and control integration determine whether a solution can meet the needs of a specific application.

1.Understand the Machine Operating Conditions

The operating process is an important factor when selecting an encoder. Equipment that runs continuously, performs frequent cycles, or needs fast recovery after interruption can benefit from absolute position technology, as it helps reduce unnecessary referencing procedures during operation.

2.Match the Encoder Length with the Actual Travel Range

The measurement length should correspond to the full stroke of the moving axis. For large-format equipment or long-travel applications, insufficient measuring coverage may limit positioning performance across the working area. Selecting an encoder with an appropriate measurement range helps maintain consistent feedback throughout the complete movement path.

3.Select Performance Based on Application Requirements

Different machines prioritize different motion characteristics. Inspection equipment may place greater emphasis on repeatability and positioning consistency, while high-speed automation systems may require a balance between response speed and accuracy. The encoder specification should be matched to the actual process requirements rather than selected only by individual parameters.

4.Confirm Integration with the Control Architecture

A suitable encoder must also work seamlessly with the existing motion control system. Communication protocol, controller compatibility, and signal processing requirements should be evaluated during system design. With BiSS-C communication, CA26 can integrate into motion platforms that require fast and dependable position data transmission.

Conclusion

For long-stroke automation systems, choosing the right encoder involves more than comparing resolution values. Position recovery capability, measurement range, accuracy, and system integration all influence the overall motion performance.

The CA26 absolute magnetic grid encoder combines absolute feedback technology and magnetic grid reliability to support precision equipment requiring stable operation, accurate positioning, and continuous production performance.
