Product Description:
The RKG5021 is an encoder feedback cable produced by Bosch Rexroth Indramat as a member of the RKG Encoder Cables series. It is supplied as a pre-terminated assembly that links serial synchronous interface encoders to Indramat drive controllers, creating the data path for real-time position transmission with minimal latency. By carrying both power and differential clock lines in a single jacket, the cable simplifies routing through drag chains and rotary axes, and it supports deterministic closed-loop motion in CNC machining centers, packaging equipment, and material-handling gantries.
It implements the serial synchronous interface, or SSI, so that each encoder can be clocked deterministically while returning position bits in a balanced pair that resists common-mode noise. Conductor identification is simplified: the negative clock lead is insulated in Yellow/Black, and the positive clock lead appears in Green/Black. A dedicated reference node of 0 V (Pin 10) is routed beside the signal pair to help prevent ground offsets that could corrupt timing. The assembly also feeds the encoder electronics with a stabilized 5 V (Pin 12) supply drawn from the drive controller, eliminating the need for local regulators and keeping wiring counts low.
At the sensor end, a keyed 12-Pin Circular connector mates directly with Rexroth encoders, ensuring correct pin alignment during installation. The two conductors that carry supply and ground are sized at 0.34 mm², providing adequate cross-section for current while maintaining flexibility. Differential data and clock pairs use a slimmer 0.14 mm² gauge so the overall cable diameter stays compact. An Internal Screen surrounds all pairs and drains interference to cabinet earth, allowing the RKG5021 to preserve bit integrity alongside high-current motor leads in tight cable trays.
