Inductive rotary encoders for robot axes: Intelligent encoders

Flat, lightweight and immune to both contamination and magnetic fields, these encoders feature a 25 mm hollow shaft and employ a scanning unit combined with either a screw-fastened circular scale or a press-fit disk/hub assembly. Wide mounting tolerances make installation easy. Mechanical fault exclusion ensures dependable mounting. And the EnDat 2.2 interface provides functionally safe data transmission. Because these encoders support an external temperature sensor, overload protection can be implemented for even greater reliability.

For two variants, HEIDENHAIN wedded the electronics directly to a metal carrier that can act as a bearing cover for the motor. This fan-out technology (FOT) saves space, reduces the number of components and dissipates heat externally through the metal plate. The resulting KCI 1318 FOT and KBI 1335 FOT encoders come with a press-fit disk/hub assembly.




For larger 30 mm and 40 mm hollow shafts, HEIDENHAIN offers the compact KCI 120 and KBI 136 inductive rotary encoders. Designed specifically for robotics applications, these encoders deliver the benefits of the smaller KBI 1300 series to robot axes that are significantly more heavy-duty.
