RG2-002ABB by Bosch Rexroth Indramat

The RG2-002ABB is an encoder cable produced by Bosch Rexroth Indramat as part of the RG2 Encoder Cables series. It links analog rotary or linear encoders to Rexroth drive controllers so that position and speed data reach the control loop without distortion during closed-loop machine operation. Classified as a Rexroth cable, this model follows the basic design layout used in the series and is intended for automated machinery where flexible cable routing and repeated motion are required.

This cable is identified as 2nd Generation, indicating updated insulation and conductor materials compared with the first release. The core bundle is arranged in a 4×2×0.25 mm² + 2×0.5 mm² pattern; the twisted signal pairs reduce crosstalk, while the larger power cores carry encoder supply voltage. An overall outer diameter of 8.5 mm allows installation through narrow energy-chain cavities. Minimum insulation resistance is rated at 500 M?/km at 20 °C, helping the drive interpret low-level feedback signals without leakage across long routing paths. Both the power and signal conductors are cleared for up to 300 V, matching typical controller auxiliary outputs and keeping the wiring set consistent across a machine and its feedback devices.

The sheath withstands up to 5 million bending cycles in drag-chain service, so frequent axis movement does not shorten cable life. When fixed, a bend is allowed down to 4×D; during continuous motion, the limit is 7.5×D, preventing conductor fatigue. A torsion tolerance of 30 °/m lets the cable twist inside robotic joints without internal strand damage. Service temperatures span -20 °C to +60 °C, covering most cabinet and machine-frame environments. The cable supports legacy sinusoidal feedback systems while maintaining electrical integrity under dynamic mechanical stress in moving machine assemblies.
