Product Description:

The RKG0076 is an encoder cable produced by Bosch Rexroth Indramat for the RKG Encoder Cables series. It is used in industrial automation to connect motor-mounted encoders to Rexroth drive controllers, transferring position feedback and auxiliary power while the axis moves. The cable supports continuous flexing in cable chains, allowing motion systems to maintain signal integrity without external slip rings or junction boxes.

This model withstands up to 2,000,000 flex cycles before fatigue becomes critical, providing the endurance needed for high-duty gantries and pick-and-place units. Its outside diameter is 9.7 mm, allowing compact routing through tight drag-chain compartments. At the motor end, the cable terminates in a 15-pin D-Sub socket connector, while the controller side has a 15-pin D-Sub pin connector. This arrangement allows installation with standard Rexroth encoder ports without pinout adapters. Eight twisted control cores are grouped as 4 × (2 × 0.14) mm² pairs to minimize crosstalk on differential signal lines, while two separate 2 × 1.0 mm² conductors deliver encoder power. During dynamic movement, the cable requires a minimum bending radius of 10 × D to prevent conductor work hardening and preserve shielding continuity. The orange RAL 2003 PUR outer jacket resists oils and cutting fluids found in machining cells.

In a stationary installation, the cable may be coiled to a minimum radius of 6 × D without overstressing the copper strands. The continuous conductor temperature can reach 80 °C, allowing operation around machinery that generates substantial heat. Low-temperature polymers keep the cable flexible at temperatures as low as -30 °C. The PUR sheath also provides abrasion resistance, helping prevent repeated cable-chain travel from exposing the shielding. Its flexible materials and compact diameter support routing through moving machine assemblies where space is limited.
