The VW3M5121R50 is a 5 m power cable from Schneider Electric, built with 4 conductors of 1.3 mm² each. It terminates in flying leads on the drive side and a metal military-style connector on the motor side — no brake wires included. This is a pre-wired connection accessory for servo drive installations where you need a fixed cable run between the drive and motor, with the connector already molded on one end.
The 5 m length is the center-to-center distance between drive and motor — enough for most cabinet-to-machine runs but short enough to avoid voltage drop on the 1.3 mm² conductors at typical servo currents. The 4 x 1.3 mm² composition means three phases plus ground (or two phases plus two control cores, depending on the drive pinout); the absence of a brake pair is explicit in the description, so if your servo motor has a holding brake, this cable will not carry those wires. The flying-lead end requires a terminal block or direct wiring inside the drive cabinet — no pre-made connector on that side.
