Rectangular Connectors - Headers, Male Pins

The 7731-102-33LF is a rectangular connector that is commonly used in the applications for wire-to-board connection. This type of component is commonly used in computer boards, cameras, data storage, and other similar applications. It is designed to connect two different boards together, while allowing the connection to remain secure in harsh environments.

The Design

The 7731-102-33LF is a two-way rectangular connector that comes with two terminal sections. It has a male pin in the center, which when inserted into the socket, makes the electrical connection. The pins are designed with an anti-torsion protection to maintain positional accuracy, even when exposed to a wide range of environmental conditions. The contact pins are gold plated, ensuring a reliable and secure electrical connection.

Operating Voltage and Temperature

The 7731-102-33LF is rated to operate with up to 10 Amps of current, with a maximum operating voltage of 125V DC. It also has a maximum temperature rating of 125°C. Additionally, this connector is designed with protection to prevent water, and other liquids, from entering into the connector to keep the connection safe and reliable.

Additional Features

In addition to providing robust electrical connections in harsh environments, the 7731-102-33LF also includes several other features that make it useful for a variety of applications. It features two screw locks, which can be used to keep the connection secure in situations where frequent connection and disconnection is necessary. Additionally, it has a conformal coating, which helps to reduce the risk of corrosion and other environmental damage to the terminal.

Working Principle

The working principle of the 7731-102-33LF is quite similar to that of other rectangular connectors. The contact pins on the connector are inserted into the pre-drilled holes on the mating socket, providing a secure connection. When the connector is placed into the socket, the screws on the sides are tightened to prevent the connector from coming loose. The contact pins make an electrical connection to the socket and provide a reliable link from the two boards.

Application Fields

The 7731-102-33LF connector is typically used in automotive, computers, data storage, and other similar applications. It is designed for wire-to-board connections, where a secure connection needs to be achieved in a wide range of environmental conditions, such as dust and moisture. In addition, its conformal coating makes it ideal for applications that have prolonged exposure to salt and humidity.
