Rectangular Connectors - Headers, Male Pins

Rectangular connectors come in a variety of shapes, sizes, and functions, from a single row of pins to a grid of pins. The M80-5111842 rectangular connector—with its high-frequency capability and shield contact block—comes in the category of Header-Male-Pin (HMP) connectors. In this article we’ll discuss this particular connector’s application field, working principle, and some alternative HMP connectors.

Application Field

M80-5111842 rectangular connectors are used in a variety of settings. They are often used in aviation, military, and industrial applications because of their high-frequency capability and shield contact block which protect the device from outside electromagnetic and radio-frequency (EMI/RFI) interference. In addition, their small size makes them well-suited for compact devices like routers, keyboards, laptop computer components, satellite dishes, and security systems.

Working Principle

The working principle of M80-5111842 rectangular connectors is relatively straightforward. They use a pin-in-socket connection, meaning that a pin is inserted into a socket and secured in place. This allows the connection to be reversible, making it easy to disconnect and reconnect components.The M80-5111842 connector features a special shield contact block, which is designed to guard against EMI/RFI interference. This feature works by absorbing the electromagnetic and radio-frequency waves, thus preventing them from reaching the device. The connector also features a high-frequency capability that makes it suitable for high-speed applications.

Alternative Connectors

There are a number of alternative connectors to the M80-5111842 rectangular connector, including the UF23-511181-2 and UF23-581841-2 HMP connectors. Both of these connectors feature Reverse Bayonet Locking (RBL) technology, which provides a secure and stable connection—even during shock and vibration. This makes them ideal for military and industrial applications.The UF23-511181-2 and UF23-581841-2 connectors also feature an anti-EMI dustproof housing, which helps reduce the amount of electromagnetic and radio-frequency interference. Additionally, these connectors are designed to be waterproof, which is a great feature for outdoor applications such as in satellites, drones, and submarines.

Conclusion

The M80-5111842 rectangular connector is a popular choice for aviation, military, and industrial applications. It features a high-frequency capability, shield contact block, and pin-in-socket connection, which all work together to guard against EMI/RFI interference and provide a secure and stable connection.Alternative HMP connectors, such as the UF23-511181-2 and UF23-581841-2, can also be used in these settings. They offer additional features like Reverse Bayonet Locking technology and anti-EMI dustproof housings, which make them especially well-suited for military and industrial applications.
