Product Details:

REXROTH 0608820069 is a high-resolution incremental angle encoder assembly for Rexroth legacy servo nutrunner tightening spindle, serving as angle feedback component for closed-loop fastening control. It captures precise rotation angle and speed data during bolt tightening cycles, cooperating with torque transducer to realize dual torque-angle monitoring. This spare encoder module belongs to discontinued tightening system series, and most available units are refurbished replacement parts for old automotive assembly lines.

This encoder assembly transmits differential incremental pulse and index signal to matched Rexroth tightening controller, providing real-time angle tracking for tightening sequence execution. It supports angle window supervision, yield point detection and thread fast run control. Homing operation is required after power cycle to establish angular reference. Separate signal cable layout reduces electromagnetic interference inside industrial cabinets with inverters and switching modules.

This variant is a standalone sensing component without motor or brake. It is installed between servo motor and gearbox of the tightening spindle, compatible with standard Rexroth spindle mounting interfaces for direct swap. The sealed encoder housing reaches IP54 protection grade to resist workshop dust and minor coolant splash. Optimized internal optical structure delivers stable pulse output under vibration environment, ensuring consistent angle measurement accuracy for safety-critical bolt joints.

It works together with Rexroth tightening software for calibration, angle tolerance setting and fastening curve recording. Every finished encoder assembly passes factory validation before shipment, including pulse phase check, angle linearity test, high-cycle endurance test and vibration inspection to guarantee stable performance in multi-shift automated fastening production lines.

It is widely deployed on automotive powertrain tightening spindles, new energy battery module fastening equipment, material torque test benches and heavy machinery bolt joining stations. Typical application scenarios include spindle angle feedback modules, fastening quality monitoring units, torque-angle dual control assemblies and mixed-model assembly sensing components. Automation integrators select this Rexroth encoder assembly for its high angular resolution, dependable pulse output and seamless matching performance with Rexroth nutrunner control ecosystem.
