Rotary electric encoders provide accurate, high resolution, absolute position with miniature to wide-diameter hollow shaft. Available with analog Sin/Cos , digital SSi , digital AqB+I outputs, these rotary encoders feature up to 20 bit resolution (with 12 bit A/D) and accuracy to <0.01°. The electric encoder non-contact technology relies on interaction between the measured displacement and a space/time modulated electric field. It offers a blend of features unequalled by optical or magnetic encoders.
