Atlas Copco Tensor DS4 D302-DS4 is a DS4-size Tensor DS drive version designed for torque‑controlled tightening within Atlas Copco Tensor DS4 systems. The Tensor DS drives do not use a traditional torque transducer; instead, they rely on Atlas Copco’s DigiTork technology to sense and regulate torque. The unit described here is rusty with no back cover, indicating a corroded housing and a missing enclosure. This condition suggests it is not ready for immediate use and would be suitable for salvage or refurbishment within a Tensor DS4 tightening setup, depending on the buyer’s assessment.
