Smaller, smarter encoders

The MicroE Optira™ series of encoders from INMOCO of Daventry is redefining performance standards for its size class. It offers up to 5nm resolution with all interpolation, automatic gain control (AGC), and signal processing performed in the sensor head. No additional PCBs, adapters, or dongles are required for operation.

Patented PurePrecision™ optical technology and industry-leading alignment tolerances make Optira’s miniature sensor head extremely easy to install. There are three mounting options and industry standard incremental encoder outputs (analog and digital). Standard FFC (flat flexible cable) connectors provide the durability and flexibility needed by designers of miniature precision motion control systems. Further, compatibility with MicroE’s wide range of linear and rotary gratings and scales enables a miniature installation footprint.

The Optira is the only encoder in its size class that offers up to 5 nm resolution with all interpolation, AGC, and signal processing performed in the sensor head. Optira’s mounting options, industry standard analog and digital incremental encoder outputs, and standard FFC connector provide the durability and flexibility needed by designers of miniature precision motion control systems. Optira is engineered to deliver industry-leading low power consumption, with an available 3.3 VDC version ideal for battery-powered precision instruments.
