Product Details:

REXROTH 109-0785-4B14-09 is a complete prefabricated shielded cable harness for Bosch Rexroth legacy modular servo nutrunner spindle. It integrates power conductors and twisted-pair signal wires inside one abrasion-resistant outer jacket, fitted with matched B14 series plug connectors for spindle and controller connection. This wiring assembly belongs to the discontinued tightening spare series, and most available units are refurbished replacement cables for old automotive fastening stations.

This cable assembly transmits power supply to the spindle servo motor and simultaneously delivers resolver or incremental encoder feedback signals. The overall shield structure suppresses electromagnetic noise generated by inverters and workshop equipment, maintaining stable torque-angle closed-loop fastening signal transmission. It supports all standard tightening sequences, and proper connector locking ensures reliable signal communication during repeated spindle movement. Separate twisted pair layout reduces cross-coupling interference between power and signal lines.

This variant is a complete wiring harness without motor, gearbox or sensing transducer. It is used for fixed automated tightening spindles and rotary multi-station fastening fixtures. The outer jacket is oil-resistant and wear-resistant, suitable for workshop environments with coolant splash and cyclic bending. The connector part adopts strain relief structure to prevent internal wire breakage from frequent movement. When connectors are properly mated, the connection end reaches IP54 protection grade against dust and incidental liquid splash.

It cooperates fully with Rexroth tightening spindles, transducers and controllers, supporting tightening program configuration and fastening data recording via Rexroth tightening software. Every finished cable passes factory validation including continuity test, insulation resistance test, shielding performance inspection and bending cycle endurance test to guarantee stable operation in multi-shift automated fastening production lines.

It is widely deployed on automotive powertrain assembly stations, new energy battery module fastening lines, household appliance bolt joining equipment and multi-spindle fastening automation cells. Typical application scenarios include spindle connection wiring assemblies, mixed-model fastening signal transmission harnesses, renovation spare cables for old nutrunner systems and replacement wiring for refurbished tightening stations. Automation integrators select this Rexroth cable harness for its integrated combined design, reliable shielding performance and seamless matching with Rexroth nutrunner tightening ecosystem.
