KK Plus Connector System

Molex KK Plus Connector System is a wire-to-board system that delivers up to 11.0A of current through two pitch sizes (2.50mm and 3.96mm) while offering design options for flexibility and efficient assembly. The KK Plus system prevents mismating by using a unique keying design and a clear audible click for connection assurance. The terminal position assurance (TPA) design provides security for the terminals inside the receptacle and prevents failure in end products by reducing terminal back-out. Molex KK Plus Connector System provides both a V0/Glow Wire combination material that provides fewer items on a bill of materials (BOM) and allows original equipment manufacturers (OEMs) to design products on a global scale. Ideal applications include automotive, consumer, industrial, medical, and telecommunications/networking.
