Most internal electronic systems are composed of wiring and connectors, terminals, and various spare parts.

The crucial function of the wire is to deliver power and signal transfer between two devices, machines, apparatuses, or instruments.

As for the internal cable system, it generally refers to Light Current Engineering.

The team specialized in developing and delivering customized specs with high-performance wiring harness components of any desired application requested.

In-house area of expertise are as followed:
- Customized connector fabrication, integrated wiring system assembly
- Stripping, crimping, labeling, and bundle wrapping, etc.

One of our areas of expertise lies in providing the comprehensive solution for water and dust protection demanded by the automotive industry for high-reliability data transfer and various outdoor applications such as surround-view cam systems, blind-spot, and parking sensors. The goal is to ensure high-reliability data transfer under any rough terrains.

The rigorous inspections and the state-of-the-art (IP rating) production assembly are the backbones of KeyJoy's quality standard.
