RG2-510AAB by Bosch Rexroth Indramat

The RG2-510AAB encoder cable is produced by Bosch Rexroth Indramat within the RG2 Encoder Cables series. Classified as a Rexroth cable and built in the encoder cable category, it forms the dedicated link between a machine-mounted digital encoder and the associated drive or controller, carrying position and speed information required for closed-loop automation. The part follows the basic construction established for the series and belongs to the second-generation range, providing consistent electrical performance while enduring mechanical stresses commonly found in dynamic industrial installations.

Its signal pair conductors have a cross section of 0.20 mm², a suitable size for low-level differential encoder pulses. Both power and signal cores share a rated insulation level of 300 V, allowing the assembly to reside next to standard machine wiring without additional separation. The PUR jacket keeps the cable intact through not less than 5,000,000 cycles of drag-chain motion, and the overall external diameter is 7.2 mm, which supports compact routing through energy chains. In static installations, the minimum bend radius is 4 x D so the internal conductor geometry is not distorted.

For moving axes, the minimum dynamic bend radius is 7.5 x D, which suits most servo axes with frequent reversals. Auxiliary cores sized 0.50 mm² are embedded to supply encoder operating voltage or service lines, and terminations are pre-fitted with an M17 Encoder Connector that locks against vibration. The cable sheath is molded from PUR (Orange RAL 2003), making the feedback cable easy to identify while also providing high abrasion resistance. This layout supports digital encoders that rely on differential transmission and provides the flexibility needed in modern pick-and-place machines.
