RG2-004ABB by Bosch Rexroth Indramat

The RG2-004ABB is an encoder feedback cable produced by Bosch Rexroth Indramat as part of the RG2 Encoder Cables series. It links MS2x rotary motors to compatible drive controllers, transmitting position data so closed-loop motion modules can maintain synchronized speed and torque in automated machinery. The cable is intended for cabinet-to-motor installations where continuous dynamic movement and extended flex life are required on gantries, pick-and-place arms, and similar axes. This role makes it suitable for applications in which the feedback path must remain stable while the machine is moving through repeated cycles.

During operation, the RG2-004ABB can be routed through continuous-motion chains while maintaining signal integrity. Its copper conductors have a cross-section of 0.50 mm², allowing low-resistance transmission of the encoder channels. The cable is rated for 5,000,000 bending cycles, and the jacket tolerates a dynamic bend radius of 7.5xD during repeated articulation. Temperature limits in service range from -20 °C to 80 °C, enabling installation alongside motors, brakes, and other heat-generating components. When the machine is idle, a static routing radius down to 4xD helps prevent conductor fatigue, and the assembly can be stored between -40 °C and 80 °C without sheath embrittlement or insulation creep.

The cable belongs to the 2nd Generation design level inside the RG2 family, combining polyethylene insulation with a fine-strand conductor lay that helps reduce torsional stress during motion. It carries analog position signals from MS2x encoders through a shielded pair that terminates in a factory-molded M17 encoder connector. Direct motor-to-drive wiring is supported for use with KMS01.2 and KMS02.1, so intermediate extension boxes are unnecessary in compatible installations. A basic outer sheath classifies the build as Basic, and the storage limit down to -40 °C allows spare assemblies to be kept in unheated facilities without degradation.
