Rectangular Connectors - Headers, Male Pins

Rectangular connectors - headers, male pins provide efficient and reliable electrical connectivity between circuits or components in a variety of different industrial and commercial applications. The two pieces of the connection can be connected with either flat, or pin-to-pin respectively, and they usually have two or more contact points to accommodate various types of circuits. Connectors come in different sizes and shapes, and the most commonly used types in electrical applications are PCB headers, DIN-type connectors, RJ45 connectors, and mini-splits. They are available in both asymmetrical (3-pin) and symmetrical (multi-pin) configurations.

The 4-102974-0-19 is a horizontally mounted, 5-pin rectangular male header that is suitable for plug-in type applications such as DIN-rail mounted power supplies. It has a 5 by 5 pin grid and features a series of pins that are arranged in a slotted pattern. The slotted pattern creates a secure mechanical connection to the device that is being connected and helps protect against accidental disconnection during operation. The connectors also feature a two-part locking mechanism that provides a visually secure connection without having to rely on the user to fasten or loosen parts of the connector.

This type of rectangular connector is most commonly used in applications such as industrial or automotive control systems, circuit boards, relay boards, or signal control systems, where reliable electrical connectivity is needed. They are also used in applications such as test and measurement, networking, telecom, medical, and lighting. Connectors of this type are available as wire-to-wire or wire-to-board versions, and many have special features like sealed construction, flexible strain reliefs, and screw mountings for easier installation and secure connections.

The working principle of the 4-102974-0-19 male connector is quite simple. When two compatible connectors are coupled together, the contact points of each piece are aligned and a mechanical connection is formed, creating a secure electrical connection. This connection is usually created by the insertion of a cutter pin into the plastic of the contact inserts. The cutter pin fastens the two pieces securely together, providing a durable connection that resists vibrations and shock.

Once the two pieces are connected together, a further connection between the two pieces is made possible by the use of a solder joint, which helps to ensure a reliable connection that resists corrosion. The solder joint also ensures that the contact points are properly aligned and that the contact force is maintained. Additionally, a contact force indicator inspects the contact force before the connectors are mounted, ensuring that a reliable connection is always made.

Thus, by providing efficient and reliable electrical connectivity, rectangular connectors - headers, male pins, such as the 4-102974-0-19, can be used in a variety of different applications. They are suitable for plug-in type applications such as DIN-rail mounted power supplies, and they feature a two-part locking mechanism for secure connections. The solder joint ensures a reliable connection that resists corrosion, and a contact force indicator helps to ensure a reliable connection is always made.
