Product Description:
The RKG5022 cable is manufactured by Bosch Rexroth Indramat for the RKG Encoder Cables series. It serves as the dedicated link between an SSI position transducer and a Rexroth drive controller, carrying both power and synchronized serial data. By combining supply conductors with differential signaling lines in a single shielded jacket, the assembly helps maintain encoder accuracy in industrial automation tasks such as gantry positioning, rotary indexing, and electronic gearing. Its construction allows quick installation between cabinet-mounted drives and field-mounted sensors, reducing wiring errors and keeping feedback latency low during cyclic motion control.
Controller-side pin mapping follows a clear logic that separates power from timing signals. The regulated encoder supply is delivered on pin 12, and the 0 V return path occupies pin 10; this pairing keeps the voltage reference stable even when cable runs are long. Clock information moves on a balanced pair: the positive clock signal leaves the drive on pin 11, while the complementary clock signal leaves on pin 13. Using two complementary conductors for every timing transition allows common-mode noise rejection over the cable length. Altogether, the harness contains 2 differential pairs—one reserved for clock transmission and the other for data—so signal integrity is preserved without the need for active repeaters.
The remaining two conductors form the SSI data channel, where the controller reads the encoder reply on pin 9 and its complement on pin 15. These lines terminate in a drive-side 15-pin D-Sub plug that mates directly with standard Rexroth control cards, while the opposite end uses an AMP angular plug tailored to many Indramat encoders. A continuous internal shield surrounds the twisted pairs to divert electromagnetic interference to ground. Current delivery is handled by copper cores sized at 0.34 mm², whereas the signal paths use finer 0.14 mm² conductors to minimize the overall cable diameter without sacrificing impedance control.
