Product Description:

The RKG5024 is a dedicated encoder cable manufactured by Bosch Rexroth Indramat and supplied within the RKG Encoder Cables series. Designed for servo drive environments, the assembly links a position transducer to the drive controller so feedback signals travel accurately between moving axes and the control cabinet. By matching mechanical plug styles and electrical pin assignments prescribed by the drive system, the cable helps automation equipment collect absolute position data and execute closed-loop motion tasks.

Its motor-side termination uses an Angular Motor Plug (AMP) that fits directly into the rotating housing without requiring extra adapters. On the encoder side, a 17-Pin Circular (Heidenhain) connector supports the differential signal lines and the shield contact used by the sensor. Twisted conductor pairs use the Green/Black; Yellow/Black color coding for the a+ and a− channels, which helps keep the signal pairs easy to identify. Serial data leaves the sensor over the SSI interface, so the cable is laid up with controlled impedance to maintain the timing margins required by synchronous serial communication.

The drive controller receives the feedback through X48 (input), X49 (replica) sockets, enabling the same signal stream to be forwarded to downstream diagnostics without additional splitters. Power for the transducer is routed on the dedicated P5V and 0V lines, isolated from the data pairs to reduce crosstalk. To compensate for voltage drop along extended runs, the harness carries Psense and Msense conductors that permit the drive to measure the actual sensor voltage at the far end and adjust its supply accordingly. An aluminum-laminate inner foil with drain wire forms the cable’s internal screen, which protects the low-level SSI words from electromagnetic interference in motor compartments.
