Automotive FAKRA To SMB5.0 Coaxial Cable

The PCM-XY-0044-X is an automotive RF coaxial cable assembly designed to connect an SMB5.0 female panel interface to a waterproof Rosenberger FAKRA Z Code connector. It provides a direct 50Ω coaxial connection between an equipment mounting panel and a compatible automotive RF interface.

The assembly combines an SMB5.0 female metal flange connector with the original Rosenberger 59Z176-C01-Z FAKRA connector, using FORCE QP12GT50-B-G 0.13 105℃ coaxial cable. The panel mounting design provides a fixed equipment connection, while the waterproof FAKRA interface supports automotive RF integration. The P1 end also undergoes a dedicated airtightness test covering the connector face and internal cavity.

Product Specifications

Connector Design & Cable Construction

SMB5.0 Panel Mounting Structure

The P1 end features an SMB5.0 female connector integrated into a metal flange plate. The two mounting holes allow the connector to be secured directly to an equipment panel or enclosure, creating a fixed RF connection point. This configuration is useful when the coaxial connection needs to pass through a housing wall rather than remain as a free hanging cable interface. The metal flange also provides a defined mounting position for equipment assembly, helping maintain consistent connector alignment during installation.

Rosenberger FAKRA Z Code IP67 Waterproof Interface

The P2 end uses the original Rosenberger 59Z176-C01-Z FAKRA Z Code connector, specified as IP67 waterproof in the engineering drawing. Its keyed housing supports correct mating orientation, while the waterproof connector design provides protection against dust and water ingress under specified mating conditions. The Z Code configuration helps identify the intended connector interface within automotive RF systems. Using the original Rosenberger part number when selecting the mating component helps maintain mechanical compatibility and avoid connector mismatches.

50Ω Coaxial Signal Transmission

The assembly uses FORCE QP12GT50-B-G 0.13 105℃ coaxial cable to maintain the RF connection between the SMB5.0 flange and FAKRA interface. The specified nominal impedance is 50Ω, with an operating frequency range from DC to 3GHz. The drawing also specifies a maximum VSWR of 1.800 and a minimum Hi-Pot requirement of 800Vrms. These electrical requirements provide the reference values for cable assembly inspection and system integration. The coaxial construction is intended for automotive RF signal connections where controlled impedance and consistent termination are important.

Flange Airtightness And Mechanical Reliability

The P1 connector face and internal cavity are subject to a dedicated airtightness test. The engineering drawing specifies a test pressure of 100KPa, followed by a defined inflation, stabilization, testing and exhaust sequence, with a specified leakage value of 30Pa. This requirement focuses on the sealing performance of the panel mounted connector end. The assembly also specifies a minimum cable retention force of 110N and an operating temperature range from -40°C to 105°C. These requirements address the mechanical and environmental conditions specified for the cable assembly.

Applications & Product Benefits

Automotive Antenna Signal Connections

Connect compatible vehicle antenna interfaces to panel mounted RF ports. The combination of an SMB5.0 flange and waterproof FAKRA connector provides a practical interface between equipment housings and automotive coaxial wiring.

Vehicle Communication Equipment

Suitable for compatible automotive RF communication modules, antenna systems and electronic equipment operating within the specified DC to 3GHz frequency range.

Sealed Electronic Enclosures

The fixed flange interface and dedicated P1 airtightness test make the assembly relevant to equipment designs where the RF connection passes through a housing panel and sealing performance needs to be verified.

Automotive RF Harness Integration

The defined connector combination and compact cable length simplify integration into equipment layouts with specific mounting and routing requirements. Premier Cable can also discuss alternative lengths and connector configurations for customized projects.
