Product Description:

The RHB2-012BBB cable is produced by Bosch Rexroth Indramat within the RHB2 Encoder Cables series and serves as the feedback and power link between MS2 servo motors and ctrlX inverters. As a hybrid solution it carries encoder signals and motor supply conductors in one sheath, allowing compact routing from the motor housing directly to a drive controller inside automation cabinets.

This model belongs to the family of Hybrid Cables, so separate resolver and power leads are not required. Current-carrying cores have a cross-section of 0.75 mm², giving adequate ampacity for the smaller MS2 frame sizes while limiting cable diameter. Mechanical endurance is rated for 5,000,000 flex cycles, suiting it to continuously moving axes on pick-and-place gantries. Motion loops are protected by a dynamic bending radius of 7.5xD, which defines the minimum loop diameter during operation. An H (M17 SpeedTec) bayonet plug terminates the drive side, enabling tool-free locking and high-vibration resistance in field installations.

The internal layout of 4x L + 2x 0.5 mm² + 4x AWG 24 - DS keeps power pairs twisted and shields the signal quartet for noise immunity. When the axis parks, the assembly may rest at a static radius of 5xD without compressive damage to insulation or shields. Compatibility is specified for MS2x (Plug H) motors and the cable mates directly with the ctrlX DRIVE system, removing intermediate terminal boxes and reducing voltage drop. A basic outer jacket and direct motor-drive topology complete the physical specification while keeping weight and installation time low.

Wake Industrial can arrange same-day shipping for urgent maintenance orders. A 1-year warranty is supplied on every cable to cover workmanship and material defects. For clarification of type codes or fault indications, the free chat tool is available to answer general technical questions.
