Overview
The FAKRA (Fachkreis Automobil, "specialist group automobile") connector is a specialized RF connector designed primarily for automotive applications. It standardizes RF connections for telematics, infotainment, safety, and communication systems within vehicles. Developed in compliance with the ISO 20860-1 and 20860-2 standards, FAKRA connectors ensure reliable high-frequency signal transmission in environments subject to vibration, temperature variations, and mechanical stress.
Features
Frequency Range: Typically up to 6 GHz, supporting high-data-rate applications such as GPS, LTE, Wi-Fi, Bluetooth, and SDARS.
Design: Uses a SMB-style coaxial interface housed in a plastic shell with color coding and mechanical keying to prevent mismating.
Color & Coding: Over a dozen mechanical codes and color options allow clear identification for specific functions (e.g., GPS, AM/FM, cellular, camera systems).
Durability: Engineered to withstand harsh automotive environments, with secure locking mechanisms and vibration resistance.

FAQ
Sample Delivery Time
Regular models require 15 days, while some complex connectors require 25 days.
Sample Fee
Most RF connectors are CNC-machined parts and do not require mold-making.
However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.
This fee will be refunded after a 5K bulk order.
Guarantee
Brass RF connectors come with a one-year warranty.
Stainless steel connectors come with a three-year warranty.
The lifespan also depends on the contact material beryllium contacts offer better durability.
ROHS & REACH Compliance
Our products fully comply with ROHS & REACH regulations.
Does LENORF Offer Military-Grade Products?
Yes. We are honored to provide military-grade products with exceptionally stable quality.

Are RF connectors weatherproof?
Some RF connectors are designed with gaskets and sealing (e.g., N-type, 4.3-10) for outdoor telecom, antennas, and harsh environments. Indoor lab connectors (e.g., SMA, BNC) are usually not weatherproof unless specified.
What’s the difference between male and female RF connectors?
Male: Has a center pin and usually an outer thread or bayonet. Female: Has a receptacle (socket) for the center pin and matching thread. Some connectors (like SMA) can be confusing because “reverse polarity” (RP-SMA) swaps pin/socket configuration.
What is VSWR, and why does it matter?
VSWR (Voltage Standing Wave Ratio) indicates signal reflection. Ideal: 1.0 (perfect match). Lower VSWR means less signal loss and distortion.
What are typical applications of RF connectors?
Telecom (5G, LTE, satellite) Aerospace & defense (radar, avionics, secure comms) Test & measurement (network/spectrum analyzers) Broadcast & video distribution Automotive radar and IoT devices Medical imaging & equipment
