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.

What is the difference between RF connectors and coaxial connectors?
They are often used interchangeably. However: Coaxial connector refers to the physical design (shielded cylindrical form). RF connector emphasizes its use in radio-frequency applications. Most RF connectors are coaxial.
What is “reverse polarity” (RP-SMA, RP-TNC)?
Reverse polarity means the gender of the center pin is swapped while keeping the outer body style unchanged. It was introduced to comply with regulatory requirements in Wi-Fi devices and to prevent connection with standard SMA/TNC.
What’s the lifespan of an RF connector?
Connector durability is rated in mating cycles: General-purpose connectors (BNC, SMA): 500 cycles. Precision connectors (2.92 mm, 2.4 mm): 500 cycles or less. Rugged telecom connectors (N, 7/16 DIN): 500 cycles.
Can RF connectors be reused?
Yes, but performance degrades with wear. Precision connectors (used in test equipment) should be handled carefully—damage to threads or pins increases VSWR and insertion loss.
