499923-9

Rectangular connectors, specifically the 499923-9 header and male pin, are ubiquitous components in electronic systems from small consumer devices to larger industrial equipment. This section covers the application field and working principle of the 499923-9 header and male pin.

Application Field

The 499923-9 is designed primarily for use on circuit boards—it has two rows of pins which are inserted into the board, with a header mounted above them to be used for connecting wires and other components. This makes it ideal for connecting circuits, lamps, switches, relays, and other high-current applications. It is commonly used in systems where access to the circuit board is limited, such as inside a computer, or in embedded systems which have a limited space for components.

Working Principle

The 499923-9 consists of a header, which is a plastic block with cavities for the two rows of pins, and two rows of male pins, which fit tightly into the header. The male pins are inserted into the holes in the circuit board, and then the header is placed over them and tightened using screws. The pins then create an electrical connection between the circuit board and the header, allowing for a simple, reliable connection for the components.

In order to reduce the risk of short circuits, the pins should be insulated properly. It is also important to ensure that the header and male pins are screwed securely in place, as this will ensure a reliable connection.

Conclusion

The 499923-9 header and male pin are a reliable, compact way to connect circuits, lamps, switches, relays and other high-current applications in limited space conditions. They are easy to use, as long as the pins are insulated properly and the header and male pins are securely screwed in place.
