Rectangular Connectors - Headers, Male Pins: 1-794631-2 Application Field and Working Principle

Rectangular connectors or headers are electromechanical components used to join two pieces of equipment together. They are usually used to make simple connections in high-speed electrical applications, and they come in a wide range of styles, connector sizes, and pin configurations. In particularly, 1-794631-2 rectangular connectors are commonly used to connect cables, enclosures, and shields in communications, industrial, and automotive applications. This article will explain the application field of 1-794631-2 rectangular connectors, alongside their working principle.

Application Field of 1-794631-2 Connectors

1-794631-2 connectors are single-row, 4-pin rectangular connectors most commonly used in communications, industrial, and automotive applications. These connectors are characterized by their small size and high pin density, making them ideal for connecting various cables, enclosures, and shields in tight spaces. In addition, the terminals (male pins) on 1-794631-2 connectors feature a top-level contact resistance, ensuring reliable connections in harsh environments. The wide range of configurations and special features offered by the 1-794631-2 connectors make them suitable for various high-speed applications, including:

• Industrial automation
• Robotics
• Medical
• Consumer products
• Automotive
• Aerospace
• Communications

Working Principle of 1-794631-2 Connectors

Typically, 1-794631-2 connectors consist of two components: a header (female) that acts as a socket, and a pin (male) that acts as an electrical contact, allowing connection with other components. To ensure reliable and established connections, 1-794631-2 connectors are fitted with an insulating section that is designed to fit around the pin, preventing electric current from bypassing the contacts.

The pins in 1-794631-2 connectors are typically contact-brushed pins, so the contact forces are minimal and provide a secure electrical connection. The header has a contact surface in which the pins are inserted. As the plugs make contact, the contact forces increase and provide a secure and efficient connection. Additionally, the header is fitted with a retaining clip that holds the pins in place and prevents them from falling out.

For better protection against dust, dirt, and moisture, 1-794631-2 connectors are fitted with a sealing material. This sealing material helps prevent the contacts from corroding and ensures a stable connection despite environmental conditions. Furthermore, male pins are coated with gold or nickel plating to further enhance their electrical and mechanical properties. This plating also increases the corrosion resistance of the connector.

Conclusion

1-794631-2 connectors are small, single-row, 4-pin rectangular connectors commonly used in communications, industrial, and automotive applications. These connectors are characterized by their small size and high pin density, making them ideal for connections in tight spaces. The pins are contact-brushed and the headers are equipped with a retaining clip to ensure reliable connections. The pins are also coated with gold or nickel plating to further increase their electrical and mechanical properties and to increase their corrosion resistance. In addition, these connectors typically feature a sealing material for greater dust and moisture protection.
