High-Speed Data connectors (also known as HSD) can meet the low-voltage, high-speed data requirements of various automotive applications. These compact shielded connectors are capable of transmitting high-frequency signals and are commonly used in automotive and industrial applications, such as systems like Ethernet, USB, and LVDS, as well as in a limited range of consumer electronic products. They offer robust signal integrity, lower electromagnetic interference (EMI), and support data rates of up to 6 Gb/s, making them suitable for advanced communication networks.

HSD connectors are part of the industry-wide efforts to address the growing demand for high-speed and reliable data transmission in automotive and industrial applications. The concept and design originated from the cooperation among connector manufacturers, including Rosenberger and TE Connectivity, aiming to standardize the data communication interfaces for applications such as Ethernet, USB, and LVDS. These applications are used in the automotive industry for infotainment systems, cameras, and Advanced Driver Assistance Systems (ADAS), as well as in automated systems in industrial environments.

Rosenberger's HSD interface is the result of cooperation with OEMs and Tier 1 suppliers, aiming to facilitate its adoption as an industry standard.

01 Design Specifications

Standardization

HSD complies with the connector requirements of the Automotive Open System Architecture (AUTOSAR), ISO and IEC standards, as well as protocols including USB, LVDS (Low-Voltage Differential Signaling), Ethernet (IEEE 802.3), Firewire (IEEE 1394), APIX (a digital serial link for point-to-point applications of displays and cameras), CAN (Controller Area Network), MHL (Mobile High-Definition Link), and PCIe.

Installation Types of HSD Connectors

Usually, the wire-to-board installation type or wire-to-wire connection is used, depending on the application.

Mating Cycles

The typical rated life of HSD is up to 500 times.

Position

HSD has 2 to 12 positions, depending on the functional requirements.

Dimensions

Width: 10 mm to 25 mm, depending on the number of pins.

Height: 5 mm and 15 mm.

Length: 20 mm to 40 mm.

HSD FAKRA connectors meet the radio frequency requirements of various telematics and multimedia applications, including Satellite Digital Audio Radio Service (SDARS), Global System for Mobile Communications (GSM), and Global Positioning System (GPS).

Contacts

Pins: 2 to 12

Pitch / Spacing: 1.27 mm

Height: 5 to 15 mm

Contact Resistance: Low; approximately 0.05 to 0.10 ohms per contact

Termination: Soldering, crimping, press-fit or screw-on

Material Specifications

The housing is usually made of polyamide (PA) or PBT (Polybutylene Terephthalate), which possess high strength, heat resistance and good electrical insulation. Thermoplastic Elastomer (TPE): Used for overmolding and gaskets, providing flexibility and sealing performance for environmental protection.

Physical Properties

nsulation: HSD connectors typically use thermoplastic insulating materials with high dielectric strength to ensure reliable signal integrity and electrical insulation.

Shielding: In addition, the connectors usually adopt metal shielding to minimize electromagnetic interference (EMI), further enhancing signal insulation and protecting the integrity of high-speed data transmission.

Locking Mechanism: The connectors are also equipped with locking mechanisms, such as snap-in or bayonet locks, to ensure secure mating in high-vibration environments such as automotive or industrial applications.

TE Connectivity's fully shielded HSD connector system supports LVDS, Ethernet and USB protocols, and features a full range of fittings and connectors suitable for both non-sealed and sealed applications.

Environmental Characteristics

IP Rating / Sealing Mechanism: The robust HSD connectors can be designed to meet IP67 or IP69K standards.

Reinforcement: Features may include metal shielding, gaskets, high-temperature resistant materials and vibration resistance.

Temperature Range: -40 °C to +105 °C or even higher, suitable for automotive applications.

Electrical Characteristics

Voltage AC/DC: Usually 5V to 12V

Current (Amperes): Up to 1A per contact (or lower in most cases).

02 Markets and Applications

Automotive, Consumer Electronics, Industrial

In automotive applications, HSD connectors are used in Advanced Driver Assistance Systems (ADAS); display, audio and multimedia interfaces; GPS, Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2X) communications; and camera systems. In industrial environments, they play a role in robots, machine vision systems and test and measurement systems. They are also used in some displays and VR headsets.
