High-Precision Optical Encoders

High precision IER3 and IERS3 optical encoders deliver two-channel quadrature signals and an additional index signal. The encoders are highly precise, due to the unique optical measuring principle. This measuring principle gives these encoders a strong edge in terms of accuracy and signal quality when compared to encoders with other measuring principles. A Faulhaber dc micro motor or brushless dc servo motor can be positioned with a typical accuracy of 0.1° to 0.3° with the IER3 and IERS3, making the encoders an ideal solution for a wide range of high precision positioning applications across markets.
