Signal acquisition and transfer, built in Shenzhen since 2006
Shenzhen Setolink Electronics Co., Ltd is a high-tech manufacturer of signal acquisition and transfer solutions, focused on one-stop supply of connectors, wires and assembled cable works — above all for the automotive field, for customers worldwide.
Beyond connection: a 3S promise
After more than fifteen years of development, our team designs, develops and produces to the differing requirements of our customers, through advanced technical means, scientific management and experienced, responsible people.
At the heart of the brand is the 3S principle — Secure, Stable, Safe — and it guides every stage of design, manufacture and testing for our wiring harnesses and connectors.
- Secure: physically secure and reliable connections, built to withstand vibration, shock and environmental stress. Every terminal crimped, every housing locked with precision.
- Stable: electrically stable, consistent performance — signal integrity and power delivery that do not fluctuate under demanding conditions.
- Safe: components designed with features that prevent short circuits, overloads and exposure to hazards, protecting equipment and people.
“The progress we have made is just the beginning”
Our long-standing dedication to stable and reliable signal solutions is rooted in a firm commitment to our values: integrity, relentless innovation, deep customer understanding, and social responsibility.
By harnessing advanced engineering and automation, we tackle complex challenges head-on, accelerating product development from concept to reality. Our agile, technology-driven teams ensure a seamless shift from prototype to production, delivering scalable solutions to market with speed and confidence.
We are energized by the road ahead and grateful to have you as our partner.

Why the company exists
Our mission. By providing excellent signal acquisition and transmission solutions, we continuously create core value for our customers and build a smarter and more interconnected world.
Our vision. To define the future of our industry as the leader in signal acquisition and transmission solutions, powered by our team's unparalleled service.
Four things we hold ourselves to
Guided by “Quality First, Customer Foremost”, we uphold integrity and a spirit of relentless innovation, and we work for mutual benefit and shared success rather than a single transaction.
Sincerity
Open communication and transparency in every business dealing and with every customer.
Innovation
The best solution comes from continuous effort and improvement in management and production.
Satisfaction
We are highly attentive to customer satisfaction with our service — it decides whether we continue to exist.
Responsibility
Sustainability and environmental protection sit at the core of our production operations.
What 2,000 m² actually contains
Wire preparation, automatic crimping, injection moulding, soldering, assembly, measurement and packing — under one roof, run by roughly 100 people.
What partners get that a trading company cannot offer
Fifteen years of signal acquisition work, condensed into six things buyers tell us actually matter.
Excellent design
Our team works in the mainstream CAD packages, reads your intent from a sketch and answers in real time. Aesthetics, material behaviour, process and cost are considered together, not in sequence.
Quick prototyping
A dedicated sampling channel runs from design review to material preparation to scheduling, using 3D printing (SLA/SLS), CNC machining and rapid prototyping — whichever proves your point fastest.
Stable production
Capacity and material are planned against your order profile, and every process step runs to a written SOP, so unit ten thousand matches unit one.
Trusted quality control
ISO 9001 management with internal standards set above it, and inspection at IQC, IPQC, FQC and OQC rather than one gate at the end.
After-sales that answers
Feedback answered within 2 hours and a solution within 24 hours; every complaint is logged, root-caused and closed through an 8D report.
3S by design
Secure mechanically, stable electrically, safe in service — the three tests every Setolink part is measured against before it ships.
