November 9, 2018 - HEIDENHAIN introduced a sealed angle encoder that 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. Called the RCN 6000 series, these absolute sealed angle encoders with integral bearings have a large hollow shaft diameter of 180mm (7.09 inches).
Common applications for the RCN 6000 encoders are large-scale rotary tables and radio telescopes which can adapt their design to the encoder while the integrated stator coupling ensures alignment of the components involved in the scanning process, even if there are deviations in the shaft coupling.
The RCN 6000 series encoders utilize HEIDENHAIN’s METALLUR process (in which the graduation is applied directly to the bearing ring) and a reflected light scanning method which gives it dimensions and larger mounting tolerances when compared to other products of its type.
The RCN 6000 encoder provides a through hole of 180mm, overall height of 44 mm, a system accuracy of ±2”, can handle speeds up to 200 rpm, able to interface with EnDat22, Fanuc05 and Mit03-4, and has an IP 64 protection.
