Product Description:

The VA-RA2474N-12-0 is a motor feedback and power cable manufactured by Kollmorgen within the Kollmorgen Servo Cables series. It routes resolver signals and drive power between a servo amplifier and a matched Kollmorgen motor, allowing closed-loop position control in automated machinery that depends on coordinated axis motion. The cable is engineered for stationary or limited-motion cable trays where accurate signal transmission, insulation stability, and environmental endurance are necessary.

An outside diameter of 9.65 mm gives the bundle thickness and guides selection of strain-relief glands. The minimum installable bend radius is 96.5 mm, so raceways must maintain that curvature to prevent conductor fatigue. Rated insulation withstand of 300 V supports typical low-voltage servo applications without exceeding jacket limits. A maximum conductor temperature of 105 °C permits service in panels that experience elevated ambient heat from drives or braking resistors. The jacket is molded from TPE, giving oil and chemical resistance while remaining flexible at common factory temperatures. Manufacturing controls keep overall diameter within a ±0.35 mm tolerance, which helps compression fittings seal without over-torque.

The cable’s shipping mass of 1.793 kg affects support hardware for vertical runs and other installations that need secure cable routing. It carries resolver leads, so its feedback medium is a Resolver; the shielded twisted pairs inside maintain low impedance for sinusoidal reference and return signals while reducing susceptibility to electrical noise. Because the assembly is not rated for static flex, it is intended for fixed or infrequently moved installations rather than continuous flex loops. It also has no dynamic flex rating, so high-cycle robotic joints should use a different Kollmorgen motion cable.
