Product Description:

The RKG0051 belongs to the RKG Encoder Cables series produced by Bosch Rexroth Indramat. It is supplied as a ready-made feedback lead that links motor-mounted encoders to drive controllers, carrying position signals while tolerating continuous motion inside cable chains and robotic joints within industrial automation cells.

The cable’s signal and power pairs are arranged as 4x0.5 mm² + 5x(2x0.14 mm²)StC, a construction that separates higher-current conductors from twisted signal pairs to control crosstalk. An overall 10.0 mm outer diameter fits standard energy-chain dividers, and the polyurethane sheath supports up to 5,000,000 flex cycles under laboratory testing. During motion, the conductors may bend down to a radius of 7.5 × D, while fixed runs may be installed at a tighter 4 × D arc without copper fatigue. These limits define routing guidelines in dynamic gantry axes and static cabinet passages to preserve conductor insulation integrity.

The raw cable material is identified as REG0011, finished in a highly visible RAL 2003 (orange) outer jacket made from resilient PUR to resist oils and weld spatter. Service temperatures range from −40 °C up to +80 °C, allowing deployment in refrigerated packaging lines or high-ambient machine halls. At one end the assembly terminates in an RGS0003 circular connector, while the opposite side uses an RGS0004 mating plug so that both motor and controller interfaces are addressed without field crimping. These molded connectors relieve strain on the copper cores, seal against dust ingress, and preserve the transmission characteristics defined by the cable’s balanced pairs.
