Beyond the Standard
3S Custom Connector Solutions for the Automotive World
Precision & Reliability

In the complex ecosystem of modern vehicles, standard connectors often fall short. Our company is the partner for automotive OEMs and Tier 1 suppliers who require tailored OBD and diagnostic port solutions. We collaborate deeply to design, engineer, and manufacture connectors that meet precise electrical, mechanical, and environmental specifications—ensuring performance, durability, and a perfect fit for your most demanding applications.

Innovation for Specific Needs

The automotive industry is diverse. A diagnostic tool for a passenger car has different needs than a heavy-duty truck’s data port, an EV battery management system tester, or a racing ECU programmer. We specialize in creating the exact connector you need.

Customization Process

We start by listening. We dive deep into your application, performance requirements, and challenges.

Our engineering team works with yours to create a solution. We consider pin-outs, housing geometry, locking mechanisms, cable length, shielding, and material selection.

We build functional prototypes for your validation, subjecting them to tests for vibration, temperature extremes, EMI/RFI interference, and mating cycle durability.

Once approved, we move into reliable, high-quality production, ensuring consistent performance from the first unit to the ten-thousandth.

What We Can Customize

Pin Configuration

We can customize male or female terminals, nickel or golden plated, brass or phosphor copper, and other specifications on your needs.

Housing & Form Factor

Low-profile, right-angle, ruggedized, or compact designs to fit constrained spaces.

Connector Gender & Type

Male, Female, or unique combinations to suit your interface needs.

Cabling & Wiring

Specific cable lengths, jacket materials (oil-resistant, high-temp), and shielding.

Materials & Color

Selection of high-grade plastics, composites, and dyes to meet aesthetic and environmental specs (e.g., UV resistance, flammability ratings).

Integrated Electronics

Adding inline components like resistors, LEDs, or simple PCBs for signal conditioning or status indication.
