Product Description:

The Bosch Rexroth Indramat RKG0074 is a flexible encoder feedback cable from the RKG Encoder Cables series. Designed as an interface between Indramat drive controllers and motor-mounted encoders, the assembly routes incremental position signals and auxiliary power through a pre-engineered harness that withstands continuous motion in cable chains. By combining dedicated supply conductors with shielded control pairs, the product provides low-noise transmission so closed-loop servo systems maintain precision during the repetitive movements common to automated packaging machines, gantry axes, and assembly robots.

The harness is manufactured from INK0280 bulk cable, a polyurethane-jacketed multicore cable that endures 5,000,000 flex cycles when installed in energy chains. For moving applications, its dynamic minimum bending radius is 7.5 × D, allowing tight routing without exceeding conductor strain limits. One end carries a sealed M23 17-pin socket (INS0379) that mates directly with Rexroth motor outlets, while the opposite side fans out into low-voltage pairs made with a 0.25 mm² control wire cross-section to minimize the bundle diameter.

The cabinet-side mating interface is a D-Sub 15-pin connector (INS0760) that secures differential encoder channels to the drive controller with spring-locked jackscrews. Power for the sensing electronics is carried on a dedicated supply pair with a cross-sectional area of 1.0 mm², which helps limit voltage drop across typical machine lengths. The supply conductors have a resistance of 19.3 ohms per kilometer, while the signal cores have a resistance of 83.0 ohms per kilometer; these values support accurate loss calculations during system setup. Mechanical stability in stationary installations requires a static bending radius of 5 × D. Electrical insulation is protected by a PUR outer sheath in orange (RAL 2003), which also makes the cable easier to identify within complex routing systems.
