Product Description:
The RKH0441 is a hybrid power and feedback cable produced by Bosch Rexroth Indramat for the RKH Hybrid Cables series. As a plug-and-play link between IndraDrive controllers and servo motors, the assembly carries three-phase power conductors together with encoder and brake lines in one sheath. By combining these functions, it simplifies wiring in automated cells, shortens installation time, and supports coordinated axis control on packaging machines, pick-and-place gantries, and other motion platforms.
The cable is supplied as a ready-made loom with crimped and overmolded connectors. Its conductor mix follows a hybrid topology that merges copper power cores with twisted signal pairs under a common shield to reduce electromagnetic crosstalk. The drive-side termination uses the keyed RHS0015 connector, while the motor end is fitted with the threaded RHS0024 plug. These coded interfaces help prevent connection to incompatible devices. During moving-cable applications such as track-mounted robots, the jacket can flex through a minimum radius of 10 × D without mechanical stress. The polyurethane insulation withstands 5,000,000 continuous bending cycles. The RKH0441 is supplied in the Basic version, which uses the standard sheath composition and shielding arrangement for general-purpose industrial environments.
For static routing inside cabinets or energy chains that remain fixed after clamping, the minimum permitted bend radius decreases to 5 × D, enabling tighter panel layouts. The lower thermal service limit is -40 °C, allowing the cable to withstand cold conditions without degradation of its dielectric strength. The upper thermal service limit is 80 °C, supporting installation near motor housings and other sources of heat. These mechanical and thermal limits help maintain signal integrity throughout repeated motion. The common shielding arrangement reduces interference between power conductors and feedback signals, while the durable jacket protects the internal conductors during flexing. Proper adherence to the stated bend radii also helps prevent excessive strain on the conductors and connector terminations.
