KR2021 Series Mini50 Wire to Board CPA Car Connector

Overview

In light of space constraints and increasing integration of electronic components in automotive interiors, automotive manufacturers have shifted their expectations of suppliers to provide more compact interconnects to accommodate the significant expansion of infotainment systems and safety features. sealed and unsealed wire-to-board receptacles in the KR2021 connector family offer device manufacturers the possibility of reducing pin, terminal and wire sizes, making it possible to efficiently package circuits in limited spaces while realizing effective cost control. Efficient packaging of circuits in limited space is possible, while realizing effective cost control. With the current trend toward integration of transportation equipment, there is a growing need for lighter, smaller, and more cost-effective wiring harnesses, and the KR2021 wiring harnesses provide the ideal solution for infotainment, lighting, and HVAC systems with excellent performance and reliability in limited spaces.

In the face of the connection reliability challenges posed by improper assembly, rough road conditions and high vibration environments in automotive applications, the KR2021 connector unsealed system significantly improves connection reliability through a series of innovative designs that effectively address the risks of inaccurate terminal insertion, operator fatigue, and disconnections caused by shock and vibration.

Advantage
