Product Description:

The RKG0054 is an encoder feedback cable produced by Bosch Rexroth Indramat for the RKG Encoder Cables series. Designed for closed-loop drives, this preterminated lead carries incremental or absolute position signals between motor-mounted encoders and the associated controller. By maintaining controlled impedance and shield continuity, the cable helps prevent jitter and electrical noise that could reduce servo accuracy in pick-and-place units, gantry axes, or CNC slides. Factory-crimped contacts eliminate the need for field soldering and help reduce installation errors on automated lines.

The cable is supplied as a ready-made assembly, so the conductors, shielding, and strain relief arrive fully terminated. Its overall length of 0.5 m suits cabinet layouts where the encoder is located close to the drive interface, keeping the loop area small and limiting crosstalk. At the motor end, an axial, coded RGS1001 connector mates with Rexroth encoders, while the controller side terminates in a right-angle RGS1004 plug that fits the corresponding evaluation board. Dynamic routing requires a minimum bending radius of 7.5 × D during motion, allowing continuous movement in cable chains or on robot arms without excessive conductor strain. When the cable is installed in a fixed track, the minimum static bending radius is 4 × D, permitting tighter cabinet routing while keeping the bend within the insulation limits.

The cable has a flex life of 5,000,000 cycles, allowing the conductors to withstand repetitive energy-chain travel through millions of strokes before insulation cracking is expected. Its service temperature ranges from -20 °C to 80 °C, allowing the cable to operate near motors, fans, or control modules that experience daily heat buildup and occasional cold starts. During storage, the cable can withstand temperatures as low as -40 °C while maintaining its dielectric strength after prolonged periods in an unconditioned storage area.
