JST KR Family Connector: KR, PHN, KRW, TR, TRW

 

The JST KR Wire-to-Wire Connector series is designed with a 2.0mm pitch and offers both disconnectable IDC (Insulation Displacement Connector) and crimp-style options, making it versatile for various wire-to-wire applications. This connector series is engineered for high-density harness mounting, enabling the efficient assembly of complex shapes and multi-harness configurations. Utilizing an automatic IDC machine, the KR connector allows for seamless insulation displacement connections, reducing the need for additional soldering or manual processes. With a range of connector types, including dual-row sockets and corresponding headers, this series offers flexibility, cost-efficiency, and reliable performance. Ideal for space-constrained designs, it supports both standard and custom circuit layouts to meet diverse application needs.
