Product Description:

The M.1302.8289 servo communication cable is manufactured by Kollmorgen within the Kollmorgen Servo Cables series. As an industrial patch cable, it links servo drives to control hardware and carries high-speed fieldbus traffic across real-time automation networks. The assembly is designed for panel-mounted or machine-mounted equipment where reliable data exchange must coexist with motor power conductors and the electromagnetic noise typical of multi-axis motion platforms.

It is classified under the CAT5e Ethernet performance grade, which supports Gigabit signaling while maintaining backward compatibility with older 100 Mb infrastructure commonly found in retrofit machinery. The overall run measures 3.0 m, providing a fixed length that avoids excess slack inside cabinets and eliminates the need for on-site termination. Each conductor is made from finely stranded copper sized at 28 AWG, allowing a smaller bend radius and reducing stress during repeated cabinet-door movements. Factory-crimped modular plugs use an 8-pin RJ-45 layout, so the cable mates directly with standard female jacks on Kollmorgen drive fronts and PLC Ethernet ports without adapters. Kollmorgen describes the product as a patch cord intended for point-to-point panel wiring. Its prefabricated ends also provide a consistent connection between compatible network devices without requiring separate modular plugs.

Transmission quality is reinforced by the shielded construction, which places the signal pairs within an overall foil shield to limit interference and crosstalk from adjacent power lines. Data integrity is further supported by the cable’s 8 individual cores, which are arranged in a twisted-pair architecture that maintains differential impedance across the full length. Kollmorgen assigns the port relationship as OUT to IN, indicating that the drive-side jack relays traffic downstream while the controller accepts it upstream. A C4 keyed connector header is fitted at the control end, while the opposite housing carries marked IN and OUT sockets. The connector shell is bonded to the cabinet ground through a drain wire, providing a continuous path for electromagnetic interference to dissipate. This grounding arrangement helps protect network traffic when the cable is routed near switched motor conductors or other sources of electrical noise.
