RG2-500ABT by Bosch Rexroth Indramat

The RG2-500ABT is an encoder interconnection product manufactured by Bosch Rexroth Indramat and supplied as part of the RG2 Encoder Cables series. It serves as the analog link between a feedback device and a drive controller in automated machinery, where stable signal transfer is required for accurate motion feedback. The cable is intended for applications that involve continuous movement inside cable chains and robotic dress packs, so it supports routing paths that flex repeatedly during normal machine operation. It is used where motion systems depend on continuous position information rather than simple on or off switching signals.

This model belongs to the 2nd Generation of the family and uses Analog Cable signal conductors. A copper conductor cross-section of 0.50 mm² balances voltage drop against cable diameter, supporting high-resolution feedback without unnecessary bulk in moving cable runs. The jacket permits a dynamic bending radius of 7.5xD. Paired with a life rating of 5,000,000 bending cycles, that flexibility helps the cable endure rapid reciprocating motion in medium-duty gantry axes while reducing conductor fatigue and helping maintain stable electrical behavior during repeated acceleration and deceleration.

The motor-side plug is the standardized M17 Encoder connector, which simplifies installation on Indramat motors that use analog encoder systems. A maximum continuous service temperature of 80 °C allows routing near warmer components, while reliable signal transfer is retained down to -40 °C during cold starts. The static installation radius is limited to 5xD, so fixed routing inside panels does not overstress the shielding layers. Storage limits match the operating temperature range, which simplifies handling before installation and during machine downtime. That arrangement is useful when part of the cable run moves with the axis while another section remains clamped in a stationary panel.
