Smaller and smarter, the innovative MicroE Optira Series Encoders from Celera Motion is the only encoder in its class to provide a resolution of up to 5 nm with all automatic gain control (AGC), interpolation, and signal processing carried out in the sensor head. Furthermore, wide alignment tolerances and patented PurePrecision optical technology make Optira’s miniature sensor head simple and easy to setup.

The Optira sensor head comes with two mounting options and a standard FFC connector that offers the flexibility and durability required by designers focused on compact precision motion control solutions. 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 only 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 interfaces 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 particularly well suited for applications where the encoder is installed in controlled environments that require compact sensor size, small overall footprint and high accuracy.
