BA43990 - RailTuff™ MVB Type Railway CAN BUS Cable with X-LSZH Material


4C (QUAD), 20AWG stranded tinned copper conductors, XL-Foam PE insulation, shielded, XL-LSZH outer jacket

Product Overview

Suitable Applications: MVB (multi functional vehicle bus) data cable for fixed and protected installations inside and outside of rail vehicles. This cable is applied for digital signal transmission with good transmission rate at the high frequencies. It is suitable for wiring of the components in the train communication network (TCN) inside the car and coach. This cable can also be used for CAN-Bus applications.This cable meets the requirements of the relevant parts of international railway standards like DIN 5510-2, EN 50153, EN 50155, EN 50305, EN 45545-2, and TJ/CL-313.
