746616-3

Rectangular connectors offer a secure connection between multiple electronic wires and components. They are most commonly used for carrying high-voltage current and are a reliable way to protect devices from damage or accidents. The 746616-3 is a rectangular connector with board in and direct wire to board varieties.

The 746616-3 is an industrial-grade connector. It has a rugged design with medium-level resistance to shock and vibration, and has a temperature range of -55°C to 125°C. It has a voltage rating of 300 volts max, and current-handling capability of 3A. It is also corrosion-resistant and has a UL 94V-O flammability rating.

The 746616-3 is generally used in industrial applications such as outdoor data centers, communication equipment, industrial control systems, and railway signaling systems. It also has automotive applications such as in electronic actuation systems, engine control systems, and electronic fuel injection systems.

The operating principle of the 746616-3 is based on a combination of mechanical and electrical locking. It has two primary components: the connector body and the pin array. The connector body is the main component and provides a strong physical connection between the pins and the board. The pin array consists of multiple metallic pins, which make a contact with insertion of the connector body into the printed circuit board.

The pin array is covered with a plastic insulator which ensures the electrical insulation of the various parts of the connector body in the system. It also prevents any electrical current from flowing through the pins and causing accidental shorts. The pins are also surrounded by a metal shell which provides additional mechanical strength and protection.

The contact between the pin array and the board is made by the springs. The springs are usually made of stainless steel or spring steel, and act to provide increased tension between the pins and the circuit board. This helps create a strong electrical contact providing consistent signal across the board.

The 746616-3 is a reliable and durable connector designed for industrial applications. It is easy to install and gives a low-resistance connection and good performance even in tough environmental conditions. Its board-in, direct wire to board design enables secure connection and ensures proper current and signal transmission at all times.
