Multi-media harnesses

Special requirements. Special features. Special cables.

It has been said that the “connected car” represents one of the greatest transformational forces in the automotive industry – this presents certain technical demands on the electrical distribution system. Vehicle features such as GPS (global positioning systems), telematics, high specification entertainment systems and on-board cameras require very high levels of data transfer, as well as screened cables to provide protection from EMI (electro-magnetic interference).

Designing and manufacturing multi-media harnesses is a special skill of the team at LEONI.

Our technical expertise delivers well-engineered products. Our products deliver connectivity and reliability.

Coaxial cable assemblies

Coaxial cable assemblies provide solutions for many of the “typical” high frequency features associated with the “connected car”.

Examples include:

  • Radio frequency (RF)
    • GPS (Global Positioning System)
    • Mobile phone
    • SDARS (Satellite Digital Audio Radio Service)
    • Telematics
    • Bluetooth & WiFi
    • Television antennas
  • Composite video (CV)
    • RSE (Rear Seat Entertainment) display video feed
    • Camera feeds – Composite Video (CV)

LEONI is an experienced partner for FAKRA coaxial cable assemblies. These connectors conform to the automotive FAKRA standard and, in combination with LEONI’s special coaxial cable, effectively convey signals to antennas, cameras and video display screens.

LEONI can support full service supply and build to print. Our extensive testing capability includes a High Frequency (HF) Vector Network Analyser (VNA) to test assemblies at the frequencies required.

High speed data

High speed data (HSD) cables support the functionality of vehicle features such as:

  • Digital cameras
  • Digital displays
  • USB (for user interface panels)
  • Ethernet high speed data (multi-media, TV etc.) 

LEONI is an experienced partner for High speed data (HSD) cable assemblies. These connectors conform to the automotive HSD standard and, in combination with special LEONI data cables, are used to effectively convey shielded high speed data for various protocols including:

  • Ethernet
  • APIX
  • USB 2.0
  • LVDS (Low Voltage Differential Signalling) 

Ethernet

New infotainment and driver assistance systems with increased data transfer rates are pushing traditional BUS-Systems like CAN, LIN and FlexRay to their limits.

The challenge is to support the requirement for increased data rates with appropriate technologies in the most economical way. “Ethernet” is a LAN technology which is already in widespread use.

The Ethernet protocol has been adapted to suit the needs of the automotive industry. The first standard was set by the OPEN ALLIANCE (BroadR-Reach); this standard is now transferred to the IEEE (IEEE 802.3bw 100Base T-1) and is already used across the industry.

LEONI is a member of the IEEE & OPEN ALLIANCE – making us the ideal partner to integrate 100Mbit Automotive Ethernet links and assemblies into the vehicle wiring system. LEONI is now focusing on the next generation of Ethernet which will provide a data transfer rate of 1000Mbits (IEEE 802.3bp 1000Base T-1).
