Product Overview

Our Auto Tin Plated Brass Connector Terminal is a precision metal terminal designed for automotive electrical connection and wiring harness applications. The brass base provides a practical balance of electrical conductivity and mechanical formability, while the tin-plated surface helps improve corrosion resistance and contact stability. The stamped terminal structure is suitable for integration into automotive connector systems where consistent dimensions, secure crimping and repeatable assembly are required.

The product is available for OEM production, custom terminal development and bulk sourcing, with dimensions and structural details configurable according to drawings or samples.

Tin-plated brass is widely used for automotive connector terminals because the plating provides a protective surface while maintaining a practical electrical contact interface. 

 Product Attributes & Specifications

Note: Exact terminal dimensions, wire-size range, mating geometry, plating thickness, current rating and connector-series compatibility should be confirmed from the customer's drawing or sample before production. These specifications should not be assumed from the product image alone.

Terminal Structure and Manufacturing Advantages

Precision Stamped Brass Terminal

The terminal is produced from formed brass material, allowing the contact geometry and crimping structure to be controlled during stamping and forming. This is important for maintaining consistent terminal dimensions across production batches.

Tin Plated Contact Surface

The tin-plated surface provides additional protection to the brass substrate against oxidation and corrosion. Tin-plated brass terminals are commonly used across automotive connector systems and wiring applications. (Sibel Electronic)

Consistent Crimping Geometry

For automotive wiring harness applications, the terminal must maintain stable positioning during crimping and insertion. Controlled stamping dimensions help support repeatable assembly when the terminal is matched with the correct connector housing and wire specification.

Strip or Reel Production

The product configuration shown can support continuous terminal production and organized packaging for higher-volume assembly requirements. Packaging format can be discussed according to the customer's assembly process.

Application Scenarios

Automotive Wiring Harnesses

Used as a metal contact component within automotive wiring harness assemblies, supporting electrical connections between wires, connector housings and vehicle electrical systems.

Automotive Electrical Components

Suitable for electrical connection systems associated with vehicle sensors, control modules, lighting, power distribution and other compatible automotive electrical assemblies, subject to terminal-series specifications.

OEM and Custom Terminal Manufacturing

We support custom automotive connector terminal development based on technical drawings, physical samples or specified terminal dimensions.

For projects requiring a particular mating interface, crimping section, locking structure or overall terminal geometry, we can evaluate the supplied technical information before confirming production feasibility.

Our custom automotive connector capability can cover:

• Drawing-based dimensions

• Sample reproduction

• Terminal geometry adjustment

• Brass material specification

• Tin-plating requirements

• Crimping-section configuration

• Packaging format

• Production quantity requirements

For an OEM automotive connector terminal project, providing the connector housing model, wire specification, terminal drawing or original sample helps us establish the correct production reference.

Quality Control

For an automotive connector terminal, dimensional consistency is critical because even small deviations can affect crimping, insertion, retention and mating compatibility.

Our inspection focus can include:

• Brass material verification

• Terminal dimensions

• Stamping and forming accuracy

• Contact geometry

• Crimping area dimensions

• Surface finish

• Tin-plating condition

• Burr and deformation inspection

• Sample-to-drawing comparison

• Packaging and quantity verification

The inspection criteria can be adjusted according to the customer's drawing and quality requirements.

B2B Supply and Bulk Production

We provide automotive connector terminals for B2B sourcing projects requiring repeatable specifications and production quantities.

For wholesale automotive connectors and wiring-component programs, we can coordinate product specifications, samples, packaging and production requirements before mass production.

For larger programs, bulk automotive connector terminals can be supplied according to agreed specifications and packaging requirements. Production quantities and MOQ should be confirmed according to the terminal structure and customization level.

As an automotive electrical connector supplier, we can also evaluate related brass terminals, connector components and other metal electrical connection parts within the same sourcing project.
