The robust, economical RI64 hollow shaft incremental encoder stands out because it is the best value for money in its class. The insulated shaft coated with hard ceramic protects the bearings effectively against motor currents. The high ingress protection, IP67, also applies to through hollow shafts and, together with the unit's high resistance to impacts and vibrations, is suitable for use in tough ambient conditions. With a line count of up to 5000, this robust encoder is suitable not only for many industrial applications but, in particular, for use as a feedback encoder for asynchronous motors.
