The HS35 series through hollow shaft and OptoPulse EIL580 series solid and hollow shaft incremental encoders are available from Baumer (Southington, CT). They use an optical scanning principle that delivers less than 1 arc minute accuracy for applications such as speed and position control for robotics. The encoders’ ShaftLock design and bearings withstand higher shaft run-outs. The encoders are available with industry standard electrical outputs and through hollow shaft diameter from 10 mm to 1 inch. MIL-connectors or cable glands allow easy installation and wiring, and various tether kits are available for mounting. Operational speed ratings are possible to 12,000 rpm. Operational temperature range is from -40 to 212 °F, and seal protection ratings are available in IP 54, IP 65, and IP 67.

The OptoPulse EIL580 is available with 6- and 10-mm shafts, as well as 8- to 15-mm blind and through hollow shaft configurations, all in standard 58-mm housing diameter. The operating temperature rating is from -40 to 185 °F. Seal protection ratings of IP 65 and IP 67 are offered, and connection options range from cable gland to M12 connector to M23 connector. Operational speed ratings of up to 6,000 rpm are possible.
