KH-FKRM-1007-04Z FAKRA RF Connector: Reliable Connection Solution for Automotive Communication

With the continuous advancement of automotive intelligence, vehicle communication, navigation, V2X and other functions have raised increasingly stringent requirements for the stability of RF signal transmission. As a core component in automotive RF links, FAKRA RF connectors are widely adopted in automotive GPS, vehicle multimedia, autonomous driving perception modules and other scenarios, thanks to outstanding anti-interference performance and consistent electrical properties. Kinghelm’s KH-FKRM-1007-04Z, a water-blue 90° board-mount FAKRA male antenna connector, is a high-performance connecting device specially designed for automotive RF signal transmission, delivering dependable RF connection solutions for various on-board devices.

This KH-FKRM-1007-04Z RF socket is a through-hole board-mounted FAKRA connector with a 90° right-angle structure, also known as a 90° male header. The right-angle design brings prominent benefits: it enables vertical redirection of signal routes during PCB layout, effectively saving internal space of equipment and perfectly fitting the compact structure of automotive electronic control units. Electronic components inside vehicles are densely arranged with limited available space. This right-angle board socket reduces bending of signal traces and avoids cable interference, facilitating structural engineers to complete overall layout. It enjoys high compatibility in vehicle navigation, infotainment hosts, T-BOX telematics boxes and other products.

In terms of appearance, this FAKRA connector is equipped with a signature water-blue plastic housing. Different housing colors of FAKRA connectors feature coding anti-misinsertion functions. Each color represents a unique code to prevent wrong mating during assembly, which would otherwise lead to communication failure. The water-blue coded version corresponds to a specific automotive RF channel. During mass production, workers can quickly identify interfaces by color, lowering assembly error rates and improving production efficiency for vehicle manufacturing. The plastic housing features temperature resistance and anti-aging properties, maintaining resistance to cracking and deformation under drastic temperature fluctuations inside vehicles for long-term service.

For electrical performance, KH-FKRM-1007-04Z strictly follows standard RF specifications with a characteristic impedance of 50Ω, the most common impedance standard for RF transmission systems. It minimizes signal reflection and loss during transmission to guarantee intact RF signal delivery. Its operating frequency ranges from DC to 6GHz, a wide bandwidth fully capable of transmitting mainstream automotive RF signals including GPS, BeiDou positioning, 4G/5G automotive communication and vehicle Wi-Fi. Stable transmission is supported for both DC and high-frequency RF signals up to 6GHz, with controlled signal attenuation to ensure clear positioning and wireless communication signals and reduce packet loss or weak signal issues.

Regarding environmental adaptability, the connector supports stable operation within a wide temperature range of -40℃ ~ +105℃. Vehicles operate across diverse environments: extreme cold in northern winters, high temperatures inside cabins after summer sunlight exposure, and thermal radiation near engine compartments all subject automotive electronics to sharp temperature changes. KH-FKRM-1007-04Z handles alternating high and low temperature conditions reliably. Its metal contacts avoid poor contact caused by thermal expansion and contraction, while insulating structures remain stable without leakage or signal crosstalk, meeting basic environmental resistance requirements for automotive-grade products.

Adopting through-hole packaging, the pins of this product are designed for direct soldering onto PCB boards. The through-hole soldering process is mature and creates robust joints. Compared with SMT connectors, through-hole structures deliver superior mechanical vibration resistance. Vehicles are constantly exposed to vibration and bumps during driving. Through-hole soldering strengthens bonding between the connector and PCB, resisting stress induced by vehicle vibration and preventing pin detachment or cold solder joints, ensuring reliable connection under long-term vibrating conditions. The single unit weighs 5.175 grams. Its compact structure does not impose extra load on PCBs. Packed in bags, it suits bulk procurement, warehouse management and assembly line feeding for manufacturers.
