Keszoox Molex 4.2mm Connectors

About

Molex 4.2mm Pitch Connectors — High-Current Wire-to-Board Interconnects for Industrial & Automotive Use The Molex 4.2mm pitch connector series is purpose-built for high-current power distribution and robust signal routing in demanding electrical environments. With a wider contact pitch than standard 3.96mm or 2.54mm families, the 4.2mm series delivers superior current-carrying capacity per pin, making it the preferred choice for motor drives, power supplies, automotive body electronics, and heavy-duty industrial wiring harnesses. Key Technical Specifications & Advantages 4.2mm Contact Pitch: Wider spacing allows larger contact cross-sections, supporting higher amperage per pin — ideal for power rails, battery management systems, and high-load switching circuits where thermal management is critical. Robust Locking Mechanism: Positive-retention housing latch ensures a secure, vibration-resistant connection that maintains mating integrity under mechanical shock, thermal expansion, and continuous vibration loads. High-Temperature Housing: UL94 V-0 rated glass-filled nylon (PA66-GF) construction withstands continuous operating temperatures up to 125°C, suitable for under-hood automotive and high-ambient industrial enclosures. Tin-Plated Copper Alloy Contacts: Optimized contact geometry delivers low insertion force with high normal force retention, ensuring stable contact resistance over thousands of mating cycles. Multiple Pin Count Options: Available in 2-pin through 12-pin configurations to accommodate diverse power and signal routing requirements within a single connector family. Wire Gauge Compatibility: Accepts 16–22 AWG wire, supporting both fine-stranded and solid-core conductors with standard Molex crimp tooling. RoHS & REACH Compliant: Fully compliant with EU environmental regulations, supporting global market access and product certification requirements. Typical Applications Automotive body control modules, lighting, and auxiliary power distributio
