Product Description:
The RKG4400 belongs to the RKG Encoder Cables series produced by Bosch Rexroth Indramat. This ready-to-install cable links an encoder to a drive controller so that position data can travel with minimal signal loss in automated machinery. Its preassembled connector and precise conductor geometry reduce wiring time and help maintain reliable encoder feedback. The cable is suitable for dynamic motion axes used on packaging lines, gantry stages, and robotic systems where repetitive movement places continuous mechanical stress on signal wiring.
The cable has a service life of 5,000,000 flex cycles, indicating how many repeated movements the jacket and conductors can withstand before fatigue becomes critical. Because the cable is supplied as a ready-made assembly, it requires no manual connector crimping, and the integrated strain relief protects the termination during movement. Moving sections must maintain a minimum dynamic bending radius of 7.5 × D, allowing the cable to curve around a radius equal to seven and a half times its outer diameter without placing excessive stress on the conductors. Fixed routing permits a tighter static bending radius of 5 × D. Signal termination is handled through a keyed M23 (12-pin) plug, which matches circular encoder sockets used on Rexroth motor feedback systems and provides secure latching under vibration.
The polymer insulation maintains its dielectric strength at temperatures down to -30 °C, supporting stable feedback during cold starts in unheated industrial facilities. The cable tolerates conductor temperatures up to +80 °C without softening the jacket. During storage, it can withstand temperatures as high as +40 °C when ambient humidity remains within normal indoor limits. Its classification as an encoder cable indicates that the conductor arrangement is intended for feedback signals between an encoder and a drive controller. The twisted-pair construction supports differential RS-422 or TTL signals and helps limit crosstalk over extended drag-chain routes. The durable polymer jacket protects the internal conductors from repeated bending while preserving the electrical characteristics needed for accurate position feedback.
