Product Description:

The VF-DAO474N-03-0 is a servo feedback cable produced by Kollmorgen within the Kollmorgen Servo Cables series. It links a motor-mounted encoder to a matching drive so that position data reaches the controller without signal loss in industrial automation cells. By pairing with Kollmorgen's SFD feedback devices, the cable maintains timing accuracy between motion axes and the supervisory PLC.

The cable is supplied in a factory-terminated length of 3 m, giving a fixed reach between the motor and cabinet without extra splicing. When routed through machine frames, it must not be bent tighter than a 67 mm radius, because staying above this limit helps prevent conductor fatigue. An overall diameter of 6.7 mm ±0.2 mm allows passage through standard cable glands while still accommodating the shield and twisted pairs. The outer jacket is molded from TPE, a thermoplastic elastomer that resists industrial oils and remains pliable after repeated thermal cycles. For thermal endurance, the conductor insulation is rated to 105 °C, so the assembly can be installed near warm motor housings without derating. Its insulation system also carries a maximum working potential of 300 V, matching low-voltage feedback interfaces in servo drives. Because the dynamic flex rating is not specified, the cable is intended for stationary or occasionally moved runs rather than continuous-motion drag chains.

An assembly mass of 0.357 kg imposes minimal load on strain-relief hardware and cable tracks. Signal conductors are wired for the SFD format, ensuring encoder supply, data, and clock lines appear on the correct pins for Kollmorgen drive connectors. The static flex capability is not rated, so the cable should be clamped in place once installed so that long-term bending does not exceed the previously noted radius or frequency limits.
