This connector uses a 2 mm pitch, which means it takes up less space on control panels and devices. Engineers and technicians often choose this connector for its ability to handle low-power signal applications in industrial automation, building systems, and test equipment. The color-coded cover and mating latches make it easy to identify and secure during installation.

The connector supports a wide range of wire sizes. It allows users to connect multiple wires at once, which helps save time and reduce errors. The design focuses on tool-free installation, so users can complete wiring tasks quickly without special tools. This feature makes the connector a popular choice in environments where speed and reliability matter.

Main Function

The main function of the 3M 37303-3101-000 FL Mini-Clamp Connector is to create a secure and efficient electrical connection between wires. It uses Insulation Displacement Contact (IDC) technology, which means the connector pierces the wire insulation and makes contact with the conductor inside. This method eliminates the need to strip wires or use crimping tools.

The connector acts as a bridge between different parts of a system, much like connector nodes in complex networks. In technical systems, connector nodes show increased activity when handling multiple tasks, supporting integration and coordination. The 373 Series connector works in a similar way by aligning and compressing different wire inputs into a single, reliable connection point. This integration improves system performance and reduces the risk of wiring mistakes.

💡 Tip: The 373 Series connector not only saves time but also increases reliability by reducing the number of steps needed for installation.

373 Series Features
