Product Description:

The RKG4400 belongs to the RKG Encoder Cables series produced by Bosch Rexroth Indramat. It is supplied as a factory-terminated assembly that links Indramat feedback devices to drive controllers, carrying position and diagnostic signals while withstanding repetitive motion inside cable chains. As an automation component, the cable simplifies encoder installation by providing pre-fitted connectors and insulation selected for continuous flex applications.

This model is rated for 5,000,000 bending cycles, indicating the number of dynamic strokes it can endure before mechanical fatigue becomes critical. It is a ready-made harness, so field crimping is unnecessary and electrical integrity is verified at production. When the cable moves with an axis, the insulation must not overstress; therefore the minimum dynamic bend radius is 7.5xD, while stationary routing may follow a tighter 5xD curve. Signal continuity is achieved through a factory-moulded M23 (12-pin) encoder connector that mates directly with Rexroth feedback devices in sealing housings.

Environmental limits define service life outside moving duties. As an encoder cable, the jacket remains flexible down to -30 °C and tolerates continuous operation up to +80 °C. During warehousing the allowable range narrows, with safe storage maintained between ambient extremes of +40 °C and −30 °C; this prevents embrittlement before installation. These temperature margins, combined with the bending figures above, confirm suitability for high-cycle gantry axes and pick-and-place systems where motion and climate stresses act simultaneously.

Wake Industrial offers a 1-year warranty on every RKG4400 cable. Same-day shipping is available for orders placed before the daily cutoff. Quotes issued for this part remain valid for 30 days to streamline budgeting.
