Product Description:

The 8BCM0020.1111A-0 is a UL/CSA listed motor cable designed for durable performance in automation environments. It provides an extended connectivity range between motors and drive systems, facilitating power and signal transmission in a wide range of systems. The motor has a length of 20 meters, offering an extended reach for installations where motors and drive systems are positioned far apart. This longer span makes integration into various machine layouts simple by eliminating the need for intermediate connectors or splicing. With this extended cable length, users can also route around obstacles or equipment for a cleaner, more efficient system design.

The 8BCM0020.1111A-0 is designed to be compatible with B&R servo motors that use motor connector size 1. It comes with a SpeedTec motor connector, size 1, that features four power and four signal contacts. This connector is rated for up to 500 mating cycles, making it suitable for fixed or semi-permanent installations where frequent disconnects are not required. When connected, the interface meets IP66/67 protection standards according to EN 60529, ensuring complete protection against dust ingress and temporary immersion in water.

The 8BCM0020.1111A-0 is designed with low conductor resistance to support efficient electrical transmission over long distances. The power lines have a maximum resistance of ≤13.7 Ω/km, which helps minimize voltage drop and maintain stable motor performance. The signal lines have a maximum resistance of ≤26.7 Ω/km, ensuring accurate and reliable transmission of control or feedback signals with minimal loss. This cable offers varying current capacities depending on installation method. It can carry up to 20 A in standard fixed installations, 17.8 A if installed in conduit or cable ducts and up to 20.9 A for cable tray installations.
