Rectangular Connectors - Headers, Male Pins:

The 641991-2 connects electrical/electronic devices. This type of cable connector enables audio, video or power signals to move between devices. Compared to cylindrical connectors, the rectangular type offers a greater number of contact pins as well as an improved coupling capacity. Moreover, the rectangular type offers greater stability, thanks to its rigid construction.

Applications:

The 641991-2 is a great choice for applications where electrical/electronic clarity is of the utmost importance. This type of connector is used for audio-video, telecommunications, data processing, automotive, medical, industrial test and control, space, marine and aviation systems. With its number of contact pins, high speed transmission, and excellent signal integrity, it is well suited for any area where bulky cables need connection.

Working Principle:

The 641991-2 consists of two parts – the plug and the socket. The plug is the male part of the connector, usually equipped with contact pins on one side and a spring latch on the other side. A socket carries the female part of the connector, fitted with contact sockets. The connectors are interconnected via dielectric medium during connection. Electrical signals pass quickly through these connectors due to their near-zero impedance.

All 641991-2 connectors are designed to prevent accidental disconnection. The plug side is mounted tightly with the spring latch, and the socket side contains different locking mechanisms which secure the plug-in connection. Additionally, the connectors may feature polarization, either due to the form or due to different pin lengths. The polarization ensures that both components of the connection are appropriately and properly aligned before electrical signals flow.

Conclusion:

The 641991-2 is the most common type of rectangular connector, making it one of the most popular electrical/electronic components in today’s fast-paced technology. Thanks to its high number of contact pins, low impedance, and secure locking mechanisms, it is widely used in many different industries all over the world.
