FAKRA (Fachkreis Automobil) Connectors are an industry standard product that is designed to exceed and satisfy the demanding environmental requirements of the worldwide automotive industry.
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.
Utilising 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.

These are a representation of some of the applications and uses of this product, and is by no means definitive.
Connector variation
- Other versions are available;
- JRF Connector (Wire to Board Type)
Retainer – Terminal Position Assurance (TPA) – Primary Lock
- The Retainer or TPA feature ensures that the crimped contact has been inserted fully into the housing. It’s a feature that aids the production/assembly process where it is not always easy to check that the crimped contact has been inserted correctly into the housing.
Secure locking device – Secondary Lock
- The housings have a locking feature that prevents accidental disconnection due to restricted wire routing or high environmental vibration.
Highly reliable contact design
- Expertly designed stamping and precision manufacturing methods offers a high degree of interface performance under conditions of vibration and temperature variation.
Application Equipment
- Semi-Automatic assembly devices are available.
Incorrect mating prevention
- 14 Mechanical and Colour Key Codes
Supper high speed performance

We 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. We have long been advocates to the aesthetics of design where you have to consider that no matter how well a product my preform if it’s boring or ugly then it’s less likely to sell!
