Precision-Engineered Single Row Molex 5557 Series 4.2mm Pitch Wire Harnesses
Jinbeili Industry Factory is a leading manufacturer of robust, custom-engineered interconnect solutions, specializing in high-performance wire harnesses and cable assemblies built around the reliable single-row Molex 5557 Series 4.2mm Pitch Wire-to-Board Connectors. This connector system is engineered for applications demanding higher current-carrying capacity, exceptional mechanical durability, and secure mating. The generous 4.2mm pitch provides superior electrical clearance and creepage, making our custom harnesses an ideal power connection solution for industrial automation equipment, automotive control systems, power supplies, medical devices, and heavy-duty appliances where safety and long-term reliability are non-negotiable.
We offer comprehensive customization to meet the precise electrical and mechanical requirements of your application. Our production capabilities cover a broad range of circuit configurations, from a simple 2-way to a comprehensive 20-way interface. We expertly manufacture harnesses using the standard part numbers for this series, including 39012020, 39012025, 39012040, 39012045, 39012060, 39012065, 39012080, 39012085, 39012100, 39012105, 39012120, 39012125, and 39012140. To accommodate varying power and signal needs, we provide a wide selection of wire dimensions, including 20AWG, 22AWG, 24AWG, and 26AWG, and offer custom wire lengths from 50mm to 1000mm, ensuring a perfect fit for your design.
The consistent quality and reliability of every harness are guaranteed by our state-of-the-art manufacturing infrastructure. Our facility is equipped with precision automated stripping and tinning machines for flawless wire preparation, alongside fully automatic housing insertion and terminating machines. This high level of automation ensures perfect, high-pressure crimps and terminations for even the largest wire gauges, batch after batch. This technological prowess is supported by our team of experienced engineers and skilled production workers, who oversee every project to ensure the highest standards are met.
To accelerate your development cycle, we support low Minimum Order Quantities (MOQ) for sample testing and provide samples rapidly, enabling you to validate performance and compatibility without delay. Our commitment to quality is further demonstrated through rigorous testing protocols. Every harness undergoes stringent validation using specialized equipment like wire force testing machines, which verify the mechanical integrity and terminal retention force of each connection, ensuring they can withstand vibration, insertion cycles, and the demands of harsh operating environments. Partner with Jinbeili for Molex 5557 Series harnesses that deliver power, precision, and proven durability.
