Overview


The KK Connector System is a trusted choice in the industry due to their durable and reliable wire-to-board and board-to-board solutions. These connectors are suitable for a wide range of low-to-mid-power applications and provide ease of use through their friction lock and polarization features that help prevent mis-mating.  

Environments that demand repetitive mating when assembling connectors can also lead to problems such as terminal back-outs, ultimately resulting in end-product failures. With locking mechanisms designed to secure mating, KK connectors help prevent terminal back-outs during connector assembly. These connectors also feature a variety of pitch sizes and circuit sizes to accommodate different design requirements, ensuring a versatile fit for various electronic assemblies. The KK Plus series expands on these capabilities by offering solutions specifically tailored for high-power applications, maintaining the design flexibility and efficiency that are characteristic of the KK series. 

These robust connectors are engineered to handle higher currents and are equipped with additional safety and retention features, making them ideal for more demanding environments where power integrity is crucial. The KK and KK Plus systems are both designed with the end user in mind, ensuring secure connections and simplified assembly processes across a multitude of industries.​
