KH-FKRM-1007-04C Blue FAKRA PCB-Mount Male Connector: Enabling More Reliable High-Frequency In-Vehicle Connectivity

As in-vehicle infotainment, intelligent driving, and connected vehicle technologies continue to evolve rapidly, stable RF signal transmission has become an essential yet often overlooked foundation of automotive electrical performance. As a critical interconnection point between antennas and modules, PCB-mounted connectors must deliver reliable high-frequency performance while withstanding vibration and temperature variations. The Kinghelm KH-FKRM-1007-04C is a blue, right-angle FAKRA male connector designed to meet these requirements.

1. Product Overview

The KH-FKRM-1007-04C is a blue FAKRA RF antenna connector designed for PCB mounting. It features a right-angle, horizontal configuration, a through-hole mounting design, and bagged packaging. Its approximate gross weight is 4.94 g per piece.

Compliant with the general FAKRA interface standard, the connector uses a color-coded identification system to enable quick and error-resistant mating. This model features blue coding, allowing it to mate accurately with the corresponding female connector while simplifying production-line assembly and maintenance identification.

The connector covers a frequency range of DC to 6 GHz, features a characteristic impedance of 50 Ω, and operates at temperatures ranging from -40°C to +105°C. Its interface diameter is 7.5 mm, and its interface length is 9.53 mm, making it suitable for flexible placement on space-constrained automotive PCBs.

2. Key Features and Advantages

1. Wide Frequency Coverage and Low Signal Loss

With a frequency range of DC to 6 GHz, the connector supports a broad range of RF applications, including 5G-connected vehicle systems, Wi-Fi 6/7, V2X communications, and GPS/GNSS. It is designed to facilitate low-loss RF transmission for high-speed data connectivity.

2. Excellent Mechanical Reliability

The 90° right-angle design helps reduce stress concentration at the cable exit, contributing to improved mechanical reliability. The connector offers a locking retention force of ≥110 N and a mating cycle rating of ≥25 cycles, balancing secure assembly with resistance to repeated mating and unmating.

3. Wide Operating Temperature Range

With an operating temperature range of -40°C to +105°C, the connector is suitable for a variety of automotive and outdoor operating environments, helping maintain stable electrical contact under extreme temperature variations.

4. Standardized Compatibility and Production-Friendly Design

Following the FAKRA interface standard, the connector features blue color coding to prevent mismating. Its through-hole mounting design is compatible with automated soldering processes, supporting efficient production and consistent quality in volume manufacturing.

3. Typical Applications

The KH-FKRM-1007-04C is suitable for RF interconnections between PCBs and various automotive components, including:

• In-vehicle infotainment head units
• T-Box and connected vehicle terminals
  
• Automotive antennas for GPS, 5G, and V2X applications

It can also be used for PCB-level RF signal transmission in wireless communication modules for industrial equipment, security and surveillance systems, and base station antennas where reliability is essential.

4. Development Trends in FAKRA PCB-Mount Connectors

FAKRA connectors are evolving beyond basic functional requirements toward enhanced standardization and higher-frequency performance.

On the one hand, the growing adoption of 5G-Advanced (5G-A) and vehicle-to-everything (V2X) communications is driving higher performance requirements for PCB-mounted interfaces operating at GHz frequencies. This places increasingly stringent demands on impedance consistency, shielding effectiveness, and electromagnetic interference (EMI) control.

On the other hand, mini-FAKRA and integrated interconnection solutions are gaining traction. These technologies enable higher connection density and faster locking mechanisms within smaller form factors, addressing the increasing PCB layout density requirements of automotive domain controllers.

Meanwhile, the growing intelligence of modern vehicles is raising the bar for automotive-grade reliability, including resistance to temperature extremes, vibration, and corrosion. Color-coded identification and automated assembly processes are also becoming increasingly important for high-volume manufacturing.

PCB-mounted products such as the KH-FKRM-1007-04C, which combine broad frequency coverage, mechanical reliability, and assembly convenience, reflect this direction of industry development.

5. Conclusion

With its blue color coding, 90° horizontal configuration, and wide DC-to-6-GHz frequency coverage, the Kinghelm KH-FKRM-1007-04C provides a practical RF interconnection solution for automotive electronics and wireless communication applications.

As FAKRA connectors continue to evolve toward higher frequencies, greater integration, and automotive-grade reliability, this connector helps engineers achieve stable, low-loss, and production-friendly RF connections within limited installation space. It is a valuable component for building reliable, high-speed connectivity architectures in next-generation vehicles.
