Product Description:
The RH2-022EBB hybrid cable is produced by Bosch Rexroth Indramat for the RH2 Encoder Cables series within the Rexroth Cables product group. In automated equipment, it connects a motor and its mounted encoder to the drive controller, combining power conductors and signal pairs in one routed bundle. This dual-function design reduces the number of separate cable runs and helps preserve reliable feedback in second-generation Rexroth motion systems. The combined arrangement can also reduce the space required in cable carriers and control panels.
The cable follows the basic design of the second-generation RH2 platform and uses an orange RAL 2003 PUR outer jacket that resists coolants and abrasion on moving machine parts. Its outside diameter measures 15.8 mm, which must be considered when calculating bend limits. Stationary routing requires a minimum bend radius of 5 × D, while energy-chain or robotic motion requires a larger minimum radius of 7.5 × D to reduce conductor stress. The power conductors have a voltage rating of 600/1000 V, and the signal conductors have a separate rating of 450/750 V. These separate insulation ratings allow the power and encoder circuits to operate within the same jacket. During dynamic operation, the assembly remains flexible at temperatures as low as -20 °C, supporting use in unheated industrial facilities.
The internal conductor arrangement includes four power cores with a cross section of 4 × 2.5 mm², two auxiliary cores arranged as 2 × 0.75 mm², and an encoder group consisting of 4 × AWG 24 conductors. A common shield reduces crosstalk between the power and signal circuits, helping protect encoder communication from electrical interference generated by the motor supply. A preinstalled M23 hybrid S connector simplifies assembly because field crimping is not required. For fixed installation, the cable can be used at ambient temperatures as low as -30 °C. Continuous operation is supported at temperatures up to +80 °C. The PUR jacket provides the flexibility and surface durability needed for repeated movement in energy chains and robotic cable routes.
