Why terminals matter

The terminal is the current or signal contact inside the connector housing. A connector RFQ should review the housing and terminal together because terminal fit, retention, wire range and crimp quality affect reliability.

Common terminal sizes

Automotive connector projects often refer to terminal series such as 0.64mm, 1.2mm, 2.8mm and 6.3mm. Smaller terminals are often used for signal circuits, while larger terminals support higher current paths.

Crimp and wire range

Terminal selection should match wire size, insulation diameter, crimp wing shape and production crimp process. Harness factories usually need sample confirmation before mass assembly.

Material and plating

Copper alloy terminals may use different plating options depending on current, environment, contact resistance and project requirement. Material and plating should be confirmed during RFQ review.

RFQ preparation

When requesting terminals, provide connector housing reference, terminal size, wire range, current requirement, application environment, sample need and annual quantity.

FAQ

Common questions

Common procurement and engineering questions related to this topic.

Can connector terminals be selected without the housing?

It is not recommended. The terminal should be checked with the connector housing, cavity structure, wire range and crimp process.

What terminal information should be included in an RFQ?

Include terminal size, wire range, current requirement, connector housing reference, material or plating requirement and sample quantity.
