Yamaichi FAKRA and HSD Connectors

By News Release | November 17, 2014

The Yamaichi FAKRA and HSD connectors portfolio for automotive applications has added a standard I/O series to its product lines.

Yamaichi FAKRA HSD connectorsFAKRA connectors are coaxial high-frequency connectors that meet the requirements of DIN20860 and USCAR 17 and 18. They are used in the transmission of a variety of signals, such as shortwave, mobile telephony, GPS, or telematics signals. Due to standardization, each application is assigned a specific color and mechanical code to ensure proper connections between the board and cable sides. Electrical transmission is specified by a differential impedance of 50 Ohms and a frequency of up to 6GHz.

Yamaichi Electronics enters the market with the HF106P series – a single-pin board connector variant. The version is available in A, C, D, H, I, and K codings, making the series ideal for radio, GPS, GSM, or auxiliary heating control applications.

For higher data transmission rates, where the one-pin FAKRA connector may no longer be sufficient, the HSD (high-speed data) interface has been defined for signals like USB or IEEE1394. For the HSD interface, signal transmission via LVDS (Low Voltage Differential Signaling) is used. This helps to prevent crosstalk between signals and interference from external signals. The system is 100-ohm impedance-controlled, to offer a high-quality signal transmission.

For the HSD specification, Yamaichi now offers its HF107P and HF108P series. The HF107P series is a four-pin HSD version with an additional shield washer, which improves EMC shielding. This variant is currently available in the color and mechanical codes B, C, and E. The second variant, HF108P, offers two additional external pins for separate power transmission. These pins can each carry 5A and are available for mechanical code D.

Both series offer 100-ohm differential impedance, two locking stages, secure connector locking, and contact protection on the pins. Of course, their design takes the special requirements of the automotive industry into consideration, so the system is specially developed and tested for environmental influences, vibrations, shock, and long service life. The metal housing is die-cast zinc, with gold-plated center contacts and tinned TH solder contacts. All products are available in tape-and-reel packaging. They are fabricated at a TS16949-certified facility.
