Backplane connectors are used to connect printed circuit boards (PCB) in a device, providing power and communication pathways for the data signals to pass between them. Specialized backplane connectors like the 88951-102LF are invaluable components in system design and optimized for use in a variety of applications. This article outlines the 88951-102LF application field and working principle.

The 88951-102LF is a low-profile, high-density backplane connector designed specifically for use in telecom and data communications applications. It features a 0.1” pitch, four (4) rows, and 62 (62) contacts. This reduced footprint allows for more efficient and compact system designs compared to traditional connectors. The pitch itself is designed with constant force contact technology, which improves the efficiency, increases the contact’s durability, provides improved EMI shielding, and eliminates any unnecessary mating force.

This connector is capable of transmitting a variety of data like Ethernet, TDM (Time Division Multiplexing), Gigabit Ethernet, Fiber Channel, and ATM (Asynchronous Transfer Mode). The low-depth design also means that it can be operated in extreme temperature and environment settings, from -40 °C to +85 °C, and from -40 to +110°C respectively. It also has an extremely low profile, which allows it to function effectively in tight footprints, such as brick and blade servers.

The 88951-102LF’s contact construction is designed to meet demanding demanding telecom and data communications requirements. Its constant force contact technology provides a secure connection. The plastic housing centers the contacts and uniform spring force deflects wafers for precise control. This prevents Electro Migration, or the movement of metal atoms that can degrade electrical signals when the contact makes and breaks.

It is also designed to provide reliable performance when transmitting high-speed data and communicates with ground plane connections. The contacts themselves are made from highly conductive copper alloy for reliable signal transmission. A unique feature of this connector is the contact recessed area; this ensures the contact is out of the air gap created by cable components used in these systems for managing airflow.

The 88951-102LF is designed with unique shielding features. Its zero insertion force contact system also includes edge shielding to control Electrical Field Susceptibility from outside sources. The shielding helps to increase the isolation of signals and prevent crosstalk. This improves performance in high-speed transmissions and provides higher immunity to EMI from other components.

The 88951-102LF’s unique design makes it a reliable and efficient solution for specific network applications. Its low profile, maximum contact density, and small footprint make it ideal for use in space-constrained systems, while its shielding and great signal transmission make it a reliable way to pass data quickly. It is highly recommended for engineers designing telecom and data communication systems.
