Product Description:
The RH2-030DBB is a hybrid encoder cable manufactured by Bosch Rexroth Indramat for the RH2 Encoder Cables series. It combines power conductors and feedback cores in one jacket, allowing a drive controller to supply a motor and receive position data without separate cable assemblies. This combined arrangement reduces the routing space required in automated machinery. The cable has a Basic design and belongs to the Rexroth Cables product group, with shielding, braiding, and dimensions suited to standardized assemblies in the platform.
The PUR jacket is rated for 5,000,000 flexing cycles in cable-track service, making the cable suitable for continuously moving axes. The copper conductors have a total cross section of 1.5 mm², which supports current transmission while limiting voltage drop across typical servo cable lengths. Mechanical stress is controlled by a minimum dynamic bend radius of 7.5 × D and a minimum static bend radius of 5 × D. Following these bend limits helps prevent conductor fatigue during installation and repeated motion. The cable can withstand temperatures up to 80 °C and as low as -40 °C, allowing operation in heated enclosures and unconditioned cold areas. Its PUR outer jacket also provides the flexibility needed for repetitive travel while protecting the internal conductors from routine mechanical wear.
The electrical conductor arrangement follows the [4x L + (2x 0.5 mm²)C + (4x AWG 24)]StC scheme. Four power conductors carry motor current, two 0.5 mm² control conductors carry auxiliary signals such as brake power, and four AWG 24 cores transmit incremental or absolute encoder data to the controller. These circuits terminate in a factory-molded M23 Hybrid plug for direct connection to compatible MSK motors without an intermediate terminal box. The cable belongs to the Hybrid Cables category and supports direct wiring without separate adapters. It is a 2nd Generation cable that uses updated insulation compounds and improved impedance control compared with earlier versions.
