RH2-025DBB by Bosch Rexroth Indramat

The RH2-025DBB is an encoder/power cable manufactured by Bosch Rexroth Indramat for the RH2 Encoder Cables series. This model links servo motors to Rexroth controllers by combining encoder feedback conductors and three-phase supply leads inside one jacket. Using a single hybrid lead reduces cabinet wiring, shortens installation time, and supports tight bend routing in automated pick-and-place systems, packaging machines, and other motion axes that require synchronized position data and drive current. The cable also supports compact routing through machine sections where moving components and limited space occur at the same time.

The cable's flex performance is rated for 5,000,000 bending cycles, so drag-chain motion does not fatigue the conductors during long duty periods. In dynamic operation, it can bend to a radius of 7.5 × D, while stationary layouts may be curved down to 5 × D; these limits help size carrier channels without overstressing the copper cores. The power conductors use a cross-sectional area of 1.5 mm² and can carry up to 15.6 A continuously without excessive temperature rise. The finely stranded design supports repeated acceleration and deceleration on multi-axis gantries and similar moving equipment.

The RH2-025DBB follows the Single-Cable Connection layout, combining encoder conductors, three power cores, and a protective drain wire within a foil-and-braid shield. Its conductor set includes power conductors of 16 AWG along with four twisted AWG-24 signal pairs that match the [4× L + (2× 0.5 mm²)C + (4× AWG 24)]StC wiring code. It is part of the Hybrid Cables group with Basic construction and belongs to the 2nd Generation of this family. This arrangement keeps feedback and power transmission together in one shielded assembly for orderly routing through moving cable paths.
