About

Molex 3.96mm KK/CH Series Connectors — Industrial-Grade Wire-to-Board Interconnects The Molex KK/CH series at 3.96mm pitch represents one of the most widely deployed wire-to-board connector families in industrial electronics. Engineered for robust power and signal transmission, these connectors are the go-to choice for applications demanding high current capacity, mechanical durability, and long-term contact reliability in demanding environments. Key Technical Advantages 3.96mm Pitch: Generous contact spacing enables higher current ratings per pin (up to 7A per contact), making this series ideal for power distribution, motor drives, and high-load switching circuits. Positive Latch Housing: The KK/CH locking tab system provides a secure, audible snap-fit connection that resists vibration-induced disconnection — essential for industrial machinery, HVAC systems, and automotive auxiliary circuits. High-Temperature Nylon Housing: UL94 V-0 rated PA66 housing withstands continuous operating temperatures up to 105°C, maintaining dimensional stability and dielectric integrity under thermal cycling. Tin-Plated Phosphor Bronze Contacts: Delivers low and stable contact resistance over extended service life, with proven performance across 30+ years of field deployment in industrial applications. Wide Pin Count Range: Available in 2-pin through 12-pin configurations, accommodating everything from simple power connectors to multi-channel control wiring harnesses. Wire Gauge Compatibility: Accepts 18–24 AWG wire, compatible with standard KK-series crimp tooling for efficient, repeatable termination in production environments. RoHS & REACH Compliant: All materials meet current EU environmental directives, supporting global product compliance requirements. Typical Applications Power supply and UPS internal wiring harnesses Industrial control panels, PLCs, and relay modules HVAC fan motor and actuator connections Automotive auxiliary power and lighting circuits LED driver boards a
