Rugged Wire-to-Wire Connectors for Aerospace and Defense
Frequently Asked Questions
What is a wire-to-wire connector?
A wire-to-wire connector creates a separable electrical and mechanical interface between two sets of wires or cables, enabling the direct transmission of power, signals or data between different components or devices. Wire-to-wire connectors are common in complex wiring harnesses and in industrial, home-appliance, automotive, transportation and consumer-electronics applications.
How do I choose the right wire-to-wire connector?
Considerations when choosing the right wire-to-wire connector include current and voltage requirements; wire gauge; available installation space; environmental conditions; vibration exposure; locking and retention requirements; and regulatory requirements. Molex offers wire-to-wire interconnect solutions ranging from compact, high-density connectors to robust high-current power connectors that support demanding applications.
Which wire-to-wire connectors are best for compact designs?
Miniaturized interconnect solutions such as PicoBlade, Nano-Fit, Micro-Fit or Micro-Lock Plus Connectors provide robust power and signal connectivity in a form factor ideal for space-constrained applications.
Are wire-to-wire connectors suitable for harsh environments?
Yes, some wire-to-wire connectors are designed with sealing and positive-locking features that help connectors withstand vibration, mechanical stress, moisture, dust and extreme temperatures. These features improve reliability and support use in demanding environments.
What is the difference between basic, enhanced and pro wire-to-wire connectors?
Wire-to-wire connectors can be categorized based on features and capabilities. Molex connectors in the basic category provide essential connectivity, including standard terminal systems. Enhanced connectors offer additional features such as positive locks, terminal position assurance and more robust designs. Pro connectors are engineered for use in demanding applications and may offer high-current capability, high circuit density, integrated secondary locking and environmental protection such as sealing.
