Features and Benefits
As applications require compact components, designers must meet ever-increasing current and power needs while also minimizing PCB footprints to conserve valuable board space. Support for diverse mechanical, electrical and environmental design requirements across multiple applications and platforms is also a challenge. Connection failures due to improper mating and operator fatigue are additional concerns in demanding assembly and operating environments.
High power density solutions in a compact connector platform enable more power per linear and square millimeter of PCB space. Diverse configuration options that accommodate a wide range of application-specific requirements and system architectures create more design flexibility for engineers. Improving assembly efficiency and providing robust mechanical retention support accurate mating and reliable, secure connections.
Supporting up to 30.0A per circuit, Mega-Fit Connectors maximize power delivery in space-constrained designs, providing a compact, high-current connector solution. Isolated contacts, mechanical keying options, potting-capable headers, blind-mating capability, color-coded housings and terminal position assurance (TPA) configurations help simplify system design and circuit identification, for accurate, secure mating. A robust positive-lock latch system and a tangless terminal design enhance retention, help prevent mis-mating and ensure long-term electrical reliability.

Frequently Asked Questions
What are Mega-Fit Connectors?
Mega-Fit Connectors are high-current wire-to-wire and wire-to-board power connectors designed to deliver up to 30.0A per circuit in a compact 5.70mm-pitch package. They are engineered for applications requiring reliable power distribution, high current density and robust mechanical performance in space-constrained designs. Multiple points of electrical contact, positive locking features and optional TPA functionality improve connection reliability across industrial, appliance, telecommunications, commercial vehicle and data center applications.
How much current do Mega-Fit Connectors carry?
Mega-Fit Connectors support up to 30.0A per circuit, making them suitable for power distribution applications that require higher current capacity than many conventional wire-to-board connector systems. The connector design has multiple independent contact points to maximize current-carrying capability while maintaining a compact footprint and reliable electrical performance.
In what kind of applications can Mega-Fit Connectors be used?
Mega-Fit Connectors are commonly used in power supplies, power distribution units, server and storage equipment, industrial automation systems, telecommunications infrastructure, commercial vehicles, renewable energy equipment and consumer appliances. These applications benefit from the connector's ability to deliver high current levels, while maintaining reliable operation in environments where vibration, temperature variation and continuous power transmission are important design considerations.
What makes Mega-Fit Connectors suitable for high-current power distribution?
Mega-Fit Connectors are designed specifically for high-current power distribution applications that require exceptional electrical performance and mechanical reliability. The system incorporates six independent points of contact, high-conductivity terminals, a robust housing design and positive locking features to maintain stable electrical connections while supporting high current loads. This helps reduce the risk of intermittent connections and supports efficient power delivery in demanding operating environments.
What are Mega-Fit ColorLock Connectors?
Mega-Fit ColorLock Connectors are color-coded and mechanically keyed versions of the Mega-Fit connector family that help prevent connector mis-mating during assembly and maintenance. By combining unique housing colors with corresponding mechanical key patterns, ColorLock connectors make it easier for operators and technicians to identify correct mating pairs. This reduces wiring errors, assembly time and the risk of equipment damage caused by incorrect connections.
How do Mega-Fit ColorLock Connectors help prevent connector mis-mating?
Mega-Fit ColorLock Connectors help prevent connector mis-mating through a combination of visual color coding and mechanically keyed housing designs. Each color corresponds to a specific key pattern, ensuring that only compatible connectors can mate together. This approach helps eliminate wiring errors in assemblies containing multiple similar connectors and improves installation accuracy, production efficiency and long-term system reliability.
Are Mega-Fit Connectors designed for harsh environments?
Yes, Mega-Fit Connectors are designed for harsh operating environments where shock, vibration and temperature fluctuations may affect connector performance. Features such as positive locking, high-retention terminals, robust housing materials and optional TPA functionality help maintain connection integrity in demanding industrial, transportation and power infrastructure applications. Specific Mega-Fit products are also designed to support stringent performance requirements for applications exposed to mechanical stress and environmental challenges.
Do Mega-Fit Connectors support PCB potting?
Select Mega-Fit headers support PCB potting processes used to improve environmental sealing and mechanical protection. Potting helps protect electronic assemblies from moisture, contamination and vibration while maintaining connectivity. Molex provides potting-capable connector options and application guidelines, enabling engineers to incorporate additional environmental protection where required.
What wire gauges are supported by Mega-Fit Connectors?
Mega-Fit Connectors support a range of wire sizes commonly used in high-current applications, including wire gauges from 18 to 10 AWG, with additional options available for specific configurations. This flexibility enables engineers to optimize conductor sizing based on application power requirements while maintaining reliable termination performance and efficient power transmission.
What is the difference between Mega-Fit and Mini-Fit Connectors?
Mega-Fit Connectors are designed for applications requiring high current capacity and support up to 30.0A per circuit with a 5.70mm pitch, while Mini-Fit Connectors provide a smaller-pitch solution for designs requiring high circuit density and low current requirements. Engineers typically select Mega-Fit Connectors when power delivery, current-carrying capability and mechanical robustness are crucial design considerations.
What do color coding and mechanical keying mean?
Mega-Fit ColorLock Connectors are visually color-coded and mechanically keyed to create a design on the molded housing that helps prevent mis-mating. Color coding means correctly mated connectors are the same color and incorrect combinations will have different colors. Natural-colored components mate to natural-colored components, and black mates to black. Keying means specific shapes, sizes and positions can mate if they match. If the connectors do not have complementary keying, they will not mate.
What is the benefit of using the double-crimp feature?
The double-crimp feature enables the termination of two wires in a single contact, eliminating the need for a separate splice. This simplifies wire harness design, reduces component count and assembly complexity, and can help lower overall harness cost while improving wiring efficiency.
