Welcome to another in the series by Nick Locke, of Nicab Ltd, who has more than 20 years experience in the electronics manufacturing industry specialising in interconnection cable assembly. This post highlights a guide to FAKRA connectors by JST.
FAKRA connectors are now a worldwide, industry standard product, designed to meet the environmental requirements of the auto industry.
You can read more about the applications and connector variations on the JST website:
“With developments in automotive communication technology and telematics, RF communication systems (incorporating coaxial cabling) have become an integral element in today’s automotive, transportation and industrial industries. The FAKRA connector standard has evolved to compliment these developments, and is based on the SMB (SubMiniature version B) design which can operate up to a Frequency of 6 GHz.
Using JST’s renowned expertise in stamping and precision manufacturing, the JRF FAKRA Connector incorporates a plastic housing design and offers a combination of 14 mechanical and colour coding elements to prevent incorrect mating. Also with primary and secondary lock features, this FAKRA connector is secure in the most challenging environments.
The JRF Connector coaxial cable Jacks and Plugs, meet USCAR and FAKRA specifications, and are compliant with ISO20860-1, -2, USCAR17 – 18 and DIN72594-1 standards. It is rated to operate within a temperature range of -40OC to +105OC and is designed to perform up to a Frequency of 6 GHz.”
I have started to see a lot of these being widely adopted into general electronics. Why? Because they are simple easy to assembly and unlikely to miss-mate. What’s more, the colour coding makes these visually interesting.
Remember, in electronics it is often overlooked that design is as much about how things can look good over how they perform. I have long been an advocate for the aesthetics of design, where you have to consider that no matter how well a product my perform, if it’s boring or ugly then it’s less likely to sell!
