ERF8-020-05.0-S-DV-K-TR is an array type mezzanine edge connector ideal for board-to-board and cable-to-board applications. Utilizing a low profile design and utilizing a variety of termination techniques, ERF8 connectors offer flexible design options. This array connector is designed to provide high-density connections between two printed circuit boards or other electronic devices.

ERF8 connectors are two row, 90°, edge-mount arrays with a 5mm pitch. They feature a patented spring-loaded “friction lock” original design that securely locks boards together for repeatable secure connections with no secondary operations or additional hardware. An integrated one-piece interposer provides additional board-to-board retention. ERF8 connectors are available with a variety of contact styles and termination techniques.

The working principle of ERF8 connector is as follows. A two-piece "self-adjusting interposer" acts like a spring and fits into two slots on the board. When the connector plates are mated, it applies a pressure into the board surface, which creates a solid and reliable contact between the two boards. The electrical connection is made via the row of pin contacts on the connector, which are in contact with corresponding receptacles on the edge of the board, thereby providing a reliable electrical connection between the two boards. Additionally, the interposer provides an additional locking feature to ensure that the decks will remain connected even when exposed to shocks and vibrations.

ERF8-020-05.0-S-DV-K-TR are suitable for various applications such as audio/video, computer, medical, telecom, and instrumentation. They are also used in power supplies, hard drives, modems, cellular phones, and printers. They are typically used in applications requiring high-speed, high-frequency, secure connections between two boards. The connectors are extremely robust and reliable, and are suitable for use in harsh environments, as well as in high-temperature applications.

ERF8-020-05.0-S-DV-K-TR connectors are highly reliable and can be employed in a variety of applications. They are suitable for use in ruggedized industrial/military applications, and can provide excellent immunity to shock and vibration. In addition, because of the tight and secure connection between the boards, ERF8 connectors provide superior signal integrity and reduce crosstalk. This makes them ideal for high-frequency applications, such as high-speed data transmission, as well as for applications requiring high-density board-to-board connections.
