The 499374-4 is a rectangular connector header specifically designed for use in a variety of different applications, such as card-edge, board-to-board, modular-dependent, and panel-mount connections. It has a 2-position screw-mated design and features a male pin. This male pin is a small but crucial component of the connector header that facilitates the secure connection of the header to the host board..

Overview

This 2-position 499374-4 header has a male pin connector termination and a spacing of 2.00 mm between the pins. It is constructed from single row, 20-pole rectangular and tin-plated copper alloy contacts, as well as a 0.50 x 0.50 inch plastic housing. Each contact is rated for a current handling of up to 1A and the insulation resistance is at least 1000MΩ. This connector is suitable for use in applications requiring a secure connection of the header to the host board.

Applications

The 499374-4 header is designed for robust performance and suitable for a wide range of applications. It is used in PCMCIA-type card-edge, board-to-board, and panel-mount connections. This header is particularly suitable for use in applications such as automotive, medical, industrial, and consumer electronics.

Working Principle

To establish a connection with the host board, a screw is used to secure the header onto the board. When the header is connected to the board, the male pin creates a connection between the board-side contacts and the host board. This connection is completed by the male pin which is then connected to the host board via a series of electrical contacts. As the male pin connects to the board, it establishes a secure and reliable connection between the header and the host board.

Conclusion

The 499374-4 is a 2-position rectangular connector header with a male pin connector termination. It is a reliable and cost-effective connector designed for use in a variety of different applications, including card-edge, board-to-board, modular-dependent, and panel-mount connections. Its male pin ensures a secure connection between the header and the host board, thus providing a secure and reliable connection for a variety of different applications.
