Backplane Connectors, consisting of a standardized subsystem of connectors, are designed to interconnect boards of several different types, as well as bus-oriented systems, without using cable harnesses or individual wires. Among these materials are pins, sockets, and contacts—the 133952-4 contacts and their applications and working principles are particularly worth noting.

The 133952-4 contacts are a type of rectangular contact, providing the benefits of enhanced keying performance, optically superb appearance, more secure connection, easy assembly, and improved quality assurance. The 133952-4 Contacts are primarily used in backplane-to-board applications, such as complimentary MEC Module Edge connectors, PC/104 Stackable DIMMs, and PMC-to-PCI interfaces. They are easy to assemble and permit secure connection, providing a snug fit when mated to their respective complementary backplane modules.

Backplane Connectors are often designed with a view towards high-density computations, which requires a faster data transmission rate, such as the 133952-4 contacts. Their rectangular form permits more contact surfaces to be used in the same design space, creating a higher contact density and allowing more contacts to be connected simultaneously. This also increases the data rate of the connector, while providing greater reliability, as fewer vibrations can cause intermittency, even during long transmissions.

The working principle of the 133952-4 contacts is simple yet efficient. The contact is designed to be inserted into a header or wave soldered on a PCB. When two opposing contacts mate, electrical current is conducted across their surface, ensuring a secure connection between two terminals. The electrical current is then directed away from the contacts and towards the device it is connecting to.

In addition to this, the 133952-4 contacts can be used to reduce crosstalk (unwanted signals that can interfere with the signal transmitted across the connection). This is achieved by increasing the IS1 impedance of the signal line, thus increasing the signal strength at the receiving end. This helps to reduce the amount of noise present along the signal line, which can adversely affect the performance of the device.

Overall, the 133952-4 contacts provide backplane connectors with a reliable connection that is capable of supporting a high-speed data transmission. Through their easily-assembled design, rectangular form, and crosstalk reduction properties, these contacts are an ideal choice for the most demanding backplane connector applications.
