Backplane connectors are used to connect electrical components on a motherboard. They are commonly used in computers and other computer-related products to reduce electrical noise and reduce cross-talk. The 1996705-4 connector is one type of backplane connector known for its reliability and durability.

The 1996705-4 connector is a modular, single-row, active only connector with eight positions. It measures 18.90mm by 15.00mm and is designed for use with flat ribbon cables, soldered directly onto the board. The 1996705-4 connector housing is made from 40% glass-filled thermoplastic (PBT) that provides superior strength and is resistant to chemicals and extreme temperatures. It complies with UL 1439 and UL94V-0 standards for flame retardancy. As far as environmental specifications, it meets or exceeds REACh, RoHS, and other global product safety protocols.

The 1996705-4 is a so-called "active" connector. This means it actively helps control electromagnetic interference (EMI) along the bus, depending on the distance of the ribbon cable from the connector. Its design allows for a compact physical package while still providing a good number of contact points on the mating connectors.

The 1996705-4 connector features two sequential contact systems. The first, known as the canted contact system, is designed to reduce cross-talk between contacts and to minimize signal loss. The second, known as the staggered contact system, is designed to reduce overall size and simplify installation by using fewer pins. The canted contact system uses a unique angled profile to reduce the overlap between adjacent contacts and helps protect signals from electrical noise. The staggered contact system uses two pairs of contacts instead of one, meaning the second pair is placed at an angle behind the first pair. This helps reduce the size of the entire system without sacrificing signal integrity.

The 1996705-4 connector also features a variety of safety features. The contact area of the contact pins is coated in a nickel-plated palladium alloy to improve contact reliability and corrosion resistance. Additionally, the connector also offers anti-popout features, which help prevent the connector from being accidentally removed from the board.

The 1996705-4 connector is an ideal choice for embedding onto a printed circuit board (PCB) and installing ribbon cables to reduce EMI. It can be safely used in applications with harsh environmental conditions, such as high humidity, dust, and extreme temperatures. Its canted and staggered contact system provides reliable and robust signal integrity while still providing a compact package. Additionally, its durable and flame-resistant PBT housing ensures longevity and stability.
