3-643818-4 Description

Short technical summary and product information.

The 3-643818-4 is a 4-position rectangular connector receptacle from TE Connectivity. It is designed for use with 20 AWG discrete or ribbon cable and terminates via IDC (Insulation Displacement Connection), eliminating the need for wire stripping. The connector features a 3.96mm pitch and a single row of contacts.

 

This receptacle has a free hanging (in-line) mounting style and is secured with a locking ramp fastening mechanism. The tin contact finish with 80µin thickness provides reliable conductivity and corrosion resistance. The connector is yellow in color and includes a closed end and polarizing key for correct alignment and protection.

 

Suitable for wire-to-wire or wire-to-board applications, this part is commonly used in electronic assemblies requiring a compact, reliable interconnection. The 3.96mm pitch allows for space-efficient wiring, and the IDC termination simplifies assembly in high-volume production.
