1、Basic Introduction
1.1 Performance parameters of FAKRA connectors
According to the parameter requirements in IS0 20860.
Main electrical performance parameters: transmission frequency 0 ~ 4GHz; characteristic impedance of 50 ohms; maximum load current 1A
Main mechanical performance parameters: latch retention force ≥ 100N error-proof force ≥ 40N

1.2 Common Applications
Wireless signal transmission: vehicle AM/FM; GPS; car networking (2~4GHz, including transmission); remote control.
Video signal transmission applications: ADAS-based outbreak, mainly applied to cameras.

1.3 Relevant Standards
Design standard: ISO20860; USCAR18
Verification standards: LV214; USCAR2; USCAR17

1.4 Adaptive Cables
Commonly used cable models: RG 174; RTK 031; RG59; RG179; RG58

1.5 Waterproofing
With the waterproof version of the harness end connector, an IPX7/IPX9K waterproof rating can be achieved at the connector pair mating interface.

2、FAKRA connector structure
2.1 The overall structure of board-end and harness-end connectors
A common FAKRA connector consists of a plastic shell, an outer conductor, a centre conductor, an insulator, a crimp sleeve (harness end connector only) and a secondary lock (harness end connector only).

2.2 Secondary lock, colour + mechanical error protection
Secondary Lock: Ensures that the terminal is mounted in place and increases the retention of the terminal. The secondary lock is usually purple.
Colour + Mechanical Misalignment Prevention: There are structures designed to prevent misalignment at the mating interface of the connector, with different coloured plastic shells for different misalignment prevention structures.
