RKG4054 by Bosch Rexroth Indramat

The RKG4054 is an encoder feedback cable produced by Bosch Rexroth Indramat within the RKG Encoder Cables series. It links servo motors or linear stages to position-control electronics so that incremental or absolute encoder signals reach the drive without loss. In automated machinery, this pre-assembled lead reduces wiring time and preserves shielding continuity between motion axes and the corresponding controller. That stable feedback path helps the controller monitor axis position and velocity during synchronized motion.

The cable is rated for 2,000,000 flex cycles, indicating its expected service life in energy-chain or cable-track assemblies that operate continuously. A molded straight plug coded as INS0701 terminates the encoder end, while the controller side uses the matching angled connector INS0643. The keyed housings help reduce pinout errors during installation. When the cable moves, its copper conductors must not bend tighter than a dynamic radius of 10 x D, where D is the outer diameter, to reduce tensile stress and insulation cracking. The assembly is part of the RKG Encoder Cables series, and it uses consistent pin assignments and braid coverage across available lengths.

Permanent routing inside a cabinet or along a machine frame may follow a static bend radius of 6 x D. The jacket material remains flexible down to -30 °C, which supports cold starts on refrigerated packaging lines, and it tolerates ambient or panel temperatures up to 80 °C before signal performance may be affected. The same storage limits apply during warehousing, which helps protect the jacket from cracking or hardening before installation. The cable can also be routed along fixed machine frames or inside enclosures where repeated bending is limited after installation. Shield continuity and strain-relief sleeves help maintain stable encoder signals during typical industrial duty cycles.
