Molex Connectors
Known for their reliability and broad utility across various industries, including automotive and consumer electronics.
The Three Types of Electrical Connectors
Electrical connectors are classified into three types based on their termination ends:
- Board-to-board connectors
- Cable/wire-to-cable/wire connectors
- Cable/wire-to-board connectors
What are Molex Connectors?
Molex connectors are a family of connectors commonly used for power and signal applications across various sectors. These connectors are manufactured by Molex Incorporated, a major provider of electronic connectors and interconnect components.
Description
Molex connectors are designed to handle both low and high current applications, offering solutions that range from simple wire-to-wire to complex multi-pin configurations. They are appreciated for their versatility and reliability in providing secure connections.
Types of Molex Connectors
| Connector Type | Pin Configuration | Current Rating | Voltage Rating | Typical Use |
|---|---|---|---|---|
| Standard | Multiple configurations | Varies | Varies | General electronics, power supplies |
| Mini-Fit Jr | 4 to 24 pins | Up to 9A | Up to 600V | PCs, appliances |
| Micro-Fit 3.0 | 2 to 24 pins | Up to 5A | Up to 250V | Data, telecom |
| Fit Power | 2 to 24 pins | Up to 23A | Up to 600V | Industrial, automotive |
Application Areas
