RH2-030DBB by Bosch Rexroth Indramat

The RH2-030DBB belongs to the RH2 Encoder Cables series from Bosch Rexroth Indramat. It is a hybrid encoder and power lead intended for direct connection between an IndraDrive controller and a synchronous servo motor, combining feedback lines and power conductors in one sheath to streamline installation in industrial automation environments. This combined format reduces cable bundle size at the axis while keeping motor power and encoder feedback in a single outer jacket. All elements are factory-terminated for direct interconnection, eliminating field crimping.

This model is categorized as Hybrid Cables and uses the conductor layout [4x L + (2x 0.5 mm²)C + (4x AWG 24)]StC. The main power cores have a cross-section of 1.5 mm², while the feedback path uses 4 (AWG 24) encoder conductors to carry differential signals with low susceptibility to noise. Mechanical endurance is rated for 5,000,000 bending cycles, which is suitable for continuously moving cable tracks. The cable is a basic design in the second generation of RH2 products, so its insulation and shielding geometry follow updated dimensional standards. Four power conductors deliver balanced three-phase energy plus protective ground, and two dedicated 0.5 mm² signal wires supply auxiliary control voltage.

The dynamic routing limit is a minimum bend radius of 7.5 x D, while static installations may use 5 x D without overstressing the copper. An allowable temperature range of -40 °C to 80 °C supports indoor machines that experience seasonal or process-related extremes. The molded M23 Hybrid motor connector mates to standard Rexroth servo housings, and the opposite end is prepared for drive-side terminal blocks. Basic flame-retardant jacketing is used, and the direct wiring style keeps electromagnetic coupling low because no intermediate junctions are present.
