ECT 818018733 To Quad SMA-J2-3 RF Cable

This professional grade automotive coaxial wire harness acts as a premium RF transition assembly, connecting a central ECT Mini Fakra 818018733 A-Code female connector to four individual SMA-J2-3 male plugs. The multi channel design leverages a robust four cavity master housing to combine separate high frequency signal paths into a single organized hub. Featuring standard inner threads with male pin terminals on the branch ends, this cable assembly utilizes top tier RTK031 equivalent coaxial wires that match Dacar302-4 and ECT302LL parameters, ensuring maximum signal fidelity and minimal attenuation over extended distances.

Designed to bridge specialized automotive hardware with industry standard testing equipment, this coaxial breakout cable offers exceptional installation flexibility. While the master ECT 818018733 connector features a sealed IP67 waterproof structure tailored for harsh vehicle environments, the separate brass gold plated SMA male ends provide secure threaded connections for central processing units, RF diagnostic tools, or GPS navigation receivers. This layout streamlines complex wire routing, offering superior shielding performance that prevents cross channel noise interference in autonomous driving vision networks.

Product Specifications

Specialized RF Connection with Gold Plated Terminals

Unlike standard plastic automotive clips, the branch ends of this assembly feature genuine gold plated brass SMA-J2-3 male connectors. The internal threading mechanism provides an exceptionally secure screw type connection that eliminates the risk of accidental disconnection caused by extreme vehicle vibrations or G forces. This threaded interface ensures uniform physical contact across the mating surface, which is critical for maintaining stable impedance and preventing intermittent signal drops during critical operations.

The high grade gold plating applied to the SMA male bodies delivers outstanding corrosion resistance and wear durability over repeated mating cycles. This protective layer shields the connector from humidity and oxidation in industrial environments, guaranteeing low contact resistance. Furthermore, the precise manufacturing of the center mating pins ensures clean high frequency energy distribution, making these branch lines perfect for high bandwidth RF testing and advanced wireless integration.

Channel Routing and RF Application

This multi channel breakout cable simplifies complex test lab and vehicle configurations by grouping four independent coaxial streams into one centralized master block. The ECT 818018733 interface connects smoothly to multi port domain controllers or high density vehicular cameras, while the four flexible branches break out to interface with external RF modules. This clever topological routing eliminates bulky individual wire bundles, leaving a clean layout that optimizes airflow and space efficiency inside tight instrument enclosures.

Each individual branch line is built with high performance RTK031 shielded wire, which provides excellent electromagnetic compatibility across all four channels. The comprehensive outer shielding structure forms an impenetrable barrier against adjacent cross talk and external ambient noise. This ensures real time, low latency data delivery, allowing autonomous driving platforms and diagnostic computing systems to process flawless high speed high definition video feeds or RF signals without distortion.

Product FAQ

Q1: Can I order different customized lengths for each of the four SMA branch lines?
A: Yes. Although we provide standard uniform length selections ranging from 0.1 meter up to 5 meters, we fully support custom harness manufacturing. You can provide your exact layout drawings to request custom branch segment lengths for each SMA-J2-3 connector to match your specific hardware configuration.

Q2: Is the entire cable assembly fully waterproof for external vehicle placement?
A: The main ECT 818018733 Mini Fakra interface features a certified IP67 waterproof sealed design for robust environmental protection. However, please note that standard threaded SMA-J2-3 connectors are generally intended for indoor testing or sealed electronic enclosures. If you require external waterproof protection for the SMA side, please contact us for specialized sealing sleeves.

Q3: What frequency range can this ECT to SMA coaxial harness support?
A: This harness utilizes high speed RTK031 coaxial cable paired with precise 50 ohm impedance connectors. It is fully optimized to support high frequency data transmission and RF signal applications, making it ideal for Gigabit Multimedia Serial Link camera setups and standard automotive diagnostic frequencies.

Q4: Is the SMA-J2-3 terminal a standard SMA or Reverse Polarity SMA?
A: This model features a standard SMA male connector, which means it has internal threads and a sharp center male pin inside. It is designed to mate with standard standard SMA female jacks with outer threads and a center hole receptor. Please verify your instrument ports before ordering.

Q5: Can this cable be used as an equivalent replacement for Dacar302-4 wires?
A: Yes. The RTK031 coaxial cable implemented in this wire assembly provides identical performance characteristics and is fully equivalent to industrial Dacar302-4 and ECT302LL specifications, allowing seamless drop in substitution for automotive validation.
