Cables & Connectors — Available Products

Overview

Siemens cables and connectors in this family cover the 6FX motion-control cable range used between Siemens drives and motors. The family holds 8 catalogued part numbers, classified as Servo / Feedback Cables (7) and Servo Drives / Amplifiers (1).

Series in this family

  • 6FX Motion Control Cables — 8 catalogued parts across the 6FX2, 6FX5 and 6FX8 order-number ranges.

The 6FX block identifies the cable generation and type — power or signal/feedback — and the trailing digits carry connector type and length. Because length and connector coding are part of the order number, a cable assembly cannot be substituted by description alone. Open the series page for the catalogued list, or send the complete 6FX order number with a quote request for a length that is not shown.
