Molex 5559 Mini Fit Connectors 4.2mm Pitch Wire Harness
Robust Custom Single-Row Molex 5559 Series 4.2mm Pitch Wire Harnesses
Jinbeili Industry Factory is a premier manufacturer of heavy-duty, custom-engineered interconnect solutions, specializing in high-performance wire harnesses and cable assemblies built around the reliable single-row Molex 5559 Series 4.2mm Pitch Wire-to-Board Connectors. This robust connector system is engineered for applications demanding higher current-carrying capacity, superior mechanical strength, and long-term reliability. The 4.2mm pitch provides excellent creepage and clearance, making our custom harnesses an ideal power connection solution for industrial machinery, automotive power systems, renewable energy applications, large appliances, and other demanding environments where electrical safety and durability are critical.
We offer extensive customization to meet the precise requirements of your power distribution and control systems. Our capabilities include producing harnesses with circuit configurations ranging from a standard 2-way to a comprehensive 20-way interface. We are proficient in manufacturing with the full suite of standard part numbers for this series, including 39012026, 39012021, 39012041, 39012046, 39012061, 39012066, 39012081, 39012086, 39012101, 39012106, 39012121, 39012126, 39012141, 39012146, 39012161, 39012166, 39012181, 39012186, and 39012206. To handle varying power requirements, we offer a wider range of wire dimensions, from 20AWG to 26AWG (20, 22, 24, 26AWG), and provide custom wire lengths from 50mm to 100mm.
The integrity of every harness is guaranteed by our state-of-the-art manufacturing infrastructure. Our production floor features precision automated stripping and tinning machines for perfect wire end preparation, coupled with fully automatic housing insertion and terminating machines. This automation is crucial for handling larger gauge wires and ensuring consistent, high-pressure crimps that withstand vibration and thermal cycling. This advanced technology is managed by our team of experienced engineers and skilled technicians, who ensure every product meets the highest standards.
To support your development cycle, we offer low Minimum Order Quantities (MOQ) for sample testing and provide samples rapidly, enabling you to validate fit, form, and function without delay. Our commitment to quality is further demonstrated through rigorous testing; every harness is validated using specialized equipment like wire force testing machines to verify the mechanical integrity and terminal retention force of every connection, ensuring ultimate reliability. Partner with Jinbeili for Molex 5559 Series harnesses that deliver power, precision, and peace of mind.
