Available Configurations
ECT Mini FAKRA B Code to Four SMA Male Cable
Connection Structure
One 818018734 four cavity female connector connects to four SMA-J2-3 straight male connectors.
Unique Difference
Each SMA termination has an internally threaded coupling nut and a center pin for mating with an SMA female port.
Suitable Installation
Suitable for equipment with accessible SMA female connections where the cable ends attach directly to the ports.
ECT Mini FAKRA B Code to Four SMA Bulkhead Female Cable
Connection Structure
One 818018734 four cavity female connector connects to four SMA-KY-2 straight female connectors with mounting nuts and washers.
Unique Difference
The threaded connector bodies support bulkhead mounting, allowing the SMA connection points to remain fixed while external cables are connected or removed.
Suitable Installation
Suitable for enclosure walls and interface panels where service connections need to remain accessible from outside the housing.
Applications & Customer Value
Camera Module Development
Engineers may need access to individual camera connections during module evaluation. Separate SMA terminations allow each connection to be included in a defined test setup without repeatedly handling the grouped equipment connector.
Enclosed Test Fixtures
A test fixture may need external connection points while the device wiring remains inside the enclosure. The bulkhead female configuration supports this arrangement and gives operators a consistent location for attaching test leads.
Prototype Equipment Integration
Prototype modules do not always use the same connector family. This harness can bridge the specified B Code interface and SMA equipment, reducing the need to redesign the module connection during an evaluation build.
Controlled Laboratory Connections
Repeatable measurements require a documented cable arrangement. Defined branch lengths, connector references and channel identification help engineering teams reproduce the same setup across multiple fixtures.
Product Features
Four Position Coaxial Termination
The common connector groups four individual coaxial contact positions within one shared connector housing. Separate cable branches carry those positions to individual SMA terminations.
Visible Housing Retention Components
The pictured ECT connector includes a red locking component and a rear cable entry structure. These parts form part of the assembled connector housing and should remain accessible within the installation layout.
Threaded SMA Coupling Mechanism
Both SMA configurations use threaded mating interfaces. The male version provides rotating coupling nuts, while the female version presents external mating threads and separate panel mounting hardware.
Environmental Protection
The ECT Mini FAKRA end uses an IP67 Waterproof connector design. The pictured SMA ends do not establish an equivalent protection rating, so exposed SMA joints require their own environmental provisions.
Customization Capabilities
Premier Cable supports:
Connector Selection and Housing Design
Premier Cable supports engineering review of connector type, gender, coding and housing requirements. Proposed alternatives are checked against the mating interface and available assembly space.
Cable Length and Branch Layout
Overall length, individual branch lengths, jacket requirements, shielding and cable structure can be reviewed for the intended routing. The cable selection is confirmed before production rather than treated as interchangeable solely by appearance.
Electrical Routing and Circuit Requirements
Pin assignment and wiring definitions can be developed from the customer drawing. Requests involving circuit configuration, resistance value or power rating require separate feasibility review and confirmation before inclusion.
OEM Production and Identification
Drawing review, prototype assembly and mass production support are available. Branch labels, product identification and packaging can be specified to match installation procedures and purchasing requirements.
Product FAQ
Q1: Is this a four way RF power splitter ?
No. It is a cable harness with four separate coaxial paths. It is not specified to divide one RF input into four outputs.
Q2: Can either version connect directly to an SMA female instrument port ?
Version 1 provides SMA male connectors for that mating arrangement. Version 2 has SMA female connectors and requires a suitable mating cable.
Q3: Does B Code establish compatibility with a particular camera or vehicle ?
No. The mating connector, contact arrangement, signal requirements and wiring definition must also match the equipment specification.
Q4: What information is needed before confirming measurement performance ?
Provide the operating frequency range, required impedance, cable lengths and acceptable signal loss. Connector appearance and cable family alone do not establish the performance of the finished assembly.
Q5: What should be supplied when requesting the bulkhead version ?
Provide panel thickness, mounting hole requirements, connector spacing, internal routing dimensions and quantity. These details allow the mounting hardware and cable layout to be reviewed together.
