Product Details:

REXROTH 109-525-2237A-3 is a hybrid shielded cable assembly designed for the legacy Bosch Rexroth modular servo nutrunner spindle system. It combines motor power lines and twisted-pair feedback signal wires within one robust outer jacket, pre-terminated with matched connectors for direct plug-and-play connection between the tightening spindle and the controller unit. This legacy cable assembly is no longer in serial production, and most available stock are refurbished spare harnesses for maintenance of existing automotive fastening stations.

This cable delivers power to the spindle servo motor while transmitting resolver or encoder feedback signals simultaneously. The overall shielding structure suppresses electromagnetic interference from inverters and surrounding production equipment, maintaining reliable signal transmission for torque and angle dual closed-loop fastening control. The internal twisted pair layout isolates power cores and signal cores to minimize crosstalk noise during continuous fastening cycles. It is a pure wiring component without built-in motor, gearbox or torque transducer.

This cable assembly is widely fitted on fixed automated tightening spindles and rotary multi-station fastening fixtures. The outer jacket adopts oil-resistant and abrasion-resistant material to withstand coolant splash and repeated bending motion. Strain relief at the connector end protects internal conductors from breakage caused by vibration and cyclic swinging. Properly locked connectors achieve IP54 protection against dust and incidental liquid splash.

It works cooperatively with Rexroth spindles, transducers and controllers. All tightening parameters and process sequences can be configured 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 fixtures and multi-spindle tightening automation cells. Typical application scenarios include spindle hybrid connection wiring assemblies, mixed-model fastening power and signal harnesses, renovation spare cables for old nutrunner systems and replacement wiring for refurbished spindle units. Automation integrators select this Rexroth 109-525-2237A-3 cable for its integrated hybrid design, reliable shielding performance and seamless matching with Rexroth nutrunner tightening ecosystem.
