PCBA optical encoders
Optira™ Series
Superior resolution, seamless integration.
Industry-Leading Miniature Feedback
The Optira Series redefines what is possible in miniature motion control, offering high-resolution performance in a footprint of just 11.4 x 13 x 3.7 mm. It is the only encoder in its size class that provides resolutions as fine as 5nm with all interpolation and automatic gain control (AGC) handled directly in the sensor head. This “smarter” design removes the need for additional PCBs or adapters, allowing for smaller, lighter, and more efficient machine builds.
Optimized for Portable Innovation
Specifically designed for modern power needs, Optira is available in an ultra-low-power 3.3VDC version, making it the ideal choice for battery-powered surgical tools and portable precision instruments. By utilizing PurePrecision technology, it ensures rapid installation and stable performance under wide mechanical tolerances. Whether used in medical devices or metrology, Optira provides the flexibility needed to push the boundaries of miniature precision.
