Product Description:
The RHB2-021DCB belongs to the RHB2 Encoder Cables series from Bosch Rexroth Indramat. This Rexroth cable links feedback devices to servo amplifiers, ensuring both power and signal lines are transferred through one sheath inside compact machines. In an automation cell it serves as the dedicated interface between MS2(x) motors and ctrlX DRIVE inverters, reducing wiring time and guaranteeing noise-immune encoder communication.
The cable is classified as Hybrid Cables, meaning power conductors share the jacket with feedback pairs to simplify routing. A factory-fitted M23 Hybrid Connector with the S-coded SPEEDCON locking system maintains IP sealing while allowing rapid tool-less mating. Current-carrying cores use a cross-section of 1.5 mm², so voltage drop remains low over typical axis lengths. During continuous motion the conductors may flex down to a dynamic radius of 7.5xD, and the PUR jacket tolerates jacket temperatures up to +80 °C without embrittlement. The electrical connection is specified as S (M23, SPEEDCON), eliminating the need for field crimping and ensuring pin-out consistency across installations.
An endurance rating of 5,000,000 bending cycles supports track-mounted gantries that operate around the clock. The cable can still start reliably at ambient temperatures as low as -40 °C, making it suitable for refrigerated packaging lines. When laid in fixed trays it only requires a static radius of 5xD, allowing dense cabinet routing. Connection to the drive is direct, so no intermediate terminal strip is needed, and the basic mechanical design remains unchanged for all lengths in the series. Alongside MS2(x) motors, the wiring scheme is harmonized with ctrlX DRIVE controllers to facilitate quick commissioning.
Wake Industrial offers a 1-year warranty on every cable, and same-day shipping is available for urgent orders. International shipping options are also supported to reach global plants. Customers can use the free chat tool for general questions about pin-outs or part codes.
