Product Description:
The RH2-022DBB is an encoder power-and-signal lead produced by Bosch Rexroth Indramat for the RH2 Encoder Cables series. It links IndraDrive or Rexroth controller ports to motor feedback devices, combining motor supply conductors and incremental sensor pairs in a single routed line so that cabinet wiring is simplified and encoder integrity is preserved in industrial automation cells.
This cable is classified as Hybrid Cables, meaning the copper bundle carries both drive power and digital feedback channels in one sheath. Inside, the conductor set follows the layout [4x L + (2x 0.5 mm²)C + (4x AWG 24)]StC; the grouped power cores and shielded twisted pairs minimise crosstalk between the motor circuit and the TTL or RS-422 signals. Each power core has a cross-section of 1.5 mm², providing low resistive loss for standard encoder currents, while the polyurethane sheath holds an overall diameter of 13.0 mm that fits common drag-chain clamps. The power element is insulated for up to 600/1000 V, enabling the line to handle typical 400 V three-phase supplies without exceeding dielectric limits.
Belonging to the 2nd Generation of Rexroth cable designs, the jacket material is PUR (Orange RAL 2003); this compound resists oils and welding spatter in machining cells. For fixed routing the assembly tolerates bends down to 5 x D, while dynamic motion axes require 7.5 × D to avoid conductor fatigue. The signal cores are rated for 450/750 V, matching common encoder transceiver voltages and maintaining insulation coordination with the power sector. The Basic cable design keeps weight and cost low yet still falls under the Rexroth Cables product group standard, ensuring connector sets and EMC terminations are compatible across the company’s feedback wiring portfolio.
