Angle Encoders Boost Accuracy In More Applications

HEIDENHAIN’s RCN 6000 sealed angle encoders can be used as an alternative to modular angular encoders for use in motion control machining applications that require a larger than usual through-hole. The absolute sealed angle encoders with integral bearings have a large hollow shaft diameter of 180 mm (7.09 in.). Common applications include large-scale rotary tables and radio telescopes which can easily adapt their design to the encoder while the integrated stator coupling ensures ideal alignment of the components involved in the scanning process, even if there are deviations in the shaft coupling.


The RCN 6000 series encoders employ the company’s METALLUR process and a reflected light scanning method. These integrated features along with the compact design keeps mounting difficulty to a minimum while making the most of its unique shape. Additionally, the encoder provides a through hole of 180 mm, overall height of 44 mm, a system accuracy of ±2”, can handle speeds up to 200 rpm, is able to interface with EnDat22, Fanuc05 and Mit03-4, and has an IP 64 protection reducing the effort required for protective measures. An RCN 6000 series datasheet awaits.
