Application context
Why this design is used
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Repeatable production indexing
Move parts between fixed stations with closed-loop encoders holding position over long shifts.
Programmable multi-axis motion
Coordinate several axes from software for processing, inspection and test sequences.
System integration
Integration and compatibility
Use these checks to connect KA050-Z to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Travel and resolution
- Travel range(mm): 50 · Closed loop resolution (µm): 1
- Separate travel from resolution and both from repeatability. Repeatability is what an automated sequence actually depends on, and it is the figure most often absent from a headline specification.
- Drive and feedback
- Open loop resolution under 20 subdivision (um): 1 · Motor and its stepping angle (°): Two-phase 57 stepping motor, 1.8
- Pair open-loop mechanics with the specified high-voltage or inertial driver, and closed-loop variants with the controller their capacitive, strain-gauge or encoder feedback requires. Matching connectors do not guarantee electrical compatibility.
