Celera Motion recently introduced its MicroE Optira Series Encoders. They are the only encoders in their class to provide a resolution of up to 5nm with all automatic gain control (AGC), interpolation, and signal processing carried out in the sensor head. Furthermore, wide alignment tolerances and PurePrecision optical technology make Optira’s miniature sensor head easy to setup.

The Optira sensor head comes with two mounting options and a standard FFC connector. In addition, the Optira consumes low power, and a 3.3 VDC version is available for use in precision instruments powered by batteries. The Optira sensor head measures 11.4 x 13 x 3.7 mm.

No additional PCBs, adapters, or dongles are necessary for the full functionality and resolution of the sensors. Optira sensors can also be universally applied with MicroE linear glass scales (to +/-1 μm/m accuracy), linear metal tape scales (to +/-5 μm/m for Optira), and rotary scales (to +/-2 arc-seconds).  The interface’s options are A-quad-B or 1Vpp sin/cos.

PurePrecision technology has enabled designers of precision motion control systems in medical, semiconductor, advanced industrial and scientific applications to design smaller, lighter and more energy efficient machines and instruments. PurePrecision technology is designed primarily for use in controlled environments that require compact sensor size, a small overall footprint and high accuracy.
