RKG0066 by Bosch Rexroth Indramat

The RKG0066 is an encoder cable produced by Bosch Rexroth Indramat within the RKG Encoder Cables series. It links position-feedback devices to drive controllers so motion data can be transferred with minimal signal loss in automated machinery. Classified under the Basic cable model, this unit is built specifically for encoder duty and is designed to maintain impedance, shielding, and pin-to-pin continuity in dynamic industrial environments. This arrangement helps position and feedback signals remain stable during repeated machine movement.

This cable is rated for 2,000,000 bending cycles, indicating how many flexing movements it can withstand before conductor fatigue becomes critical. The cable has a 10xD dynamic bending radius for moving installation and a 6xD static bending radius for fixed routing, which helps limit mechanical stress on the cores. Operational service is allowed from -30 °C up to 80 °C, covering common factory temperature conditions without derating. During storage, those same thermal limits remain valid, so standard indoor storage conditions are generally suitable. The copper conductors at one end terminate on a solder contact assembly, while the opposite end uses crimped contacts for a secure connection.

The twin connectors exit the jacket at a 2×45° cable exit, which eases routing in cramped control cabinets and reduces strain on the backshells. At the drive side, a D-Sub 15 socket provides a shield-to-ground path through its metal shell, while the encoder side uses a D-Sub 15 pin that mates directly with typical feedback transducers. Both plug ends are enclosed in metallic shielded housings, which work with the braided screen to suppress electromagnetic interference. This shielding helps preserve clean signal transmission where nearby motors, drives, and switching devices may introduce electrical noise.
