This unique, patented, design combines light source and photo detector mounting in the same plane facing the code wheel, the complete surface of which is reflective, ensuring the majority of incoming light (>90%) be reflected on the light sensor.

The precision of the code wheel, the focusing of the light beam and the use of a CMOS control circuit achieve a high slew rate and very tight signal tolerances. A code wheel with 128 reflectors yields an angular tolerance of less than ± 0.14°, proving the design of miniaturized precise angle sensors is possible and highly efficient.

The reliable EO1 R007 achieves higher signal selectivity than comparable reflective systems, being a factor two better.  The high output signals precision allows the system to retain its accuracy after 2 and 4 fold interpolations.

The optical encoder is available as a modular system in kit form, giving customers the option to integrate the sensor and code wheel kit in an existing housing, motor or system. Alternatively the encoder system can be integrated as a universal encoder in a preferred housing.
