SEAF8-20-05.0-S-04-2-K Description

Short technical summary and product information.

The SEAF8-20-05.0-S-04-2-K is a member of Samtec's SEARAY series of high-speed, high-density open-pin-field array sockets. It features 80 positions arranged in 4 rows on a compact 0.80mm pitch, enabling significant board space savings compared to traditional 1.27mm pitch connectors. The connector uses Samtec's rugged Edge Rate contact system, providing reliable performance in demanding environments.

 

The socket is rated for 1.3A per pin (with 10 adjacent pins powered) and 220VAC / 311VDC maximum voltage. It supports data rates up to 28 Gbps NRZ and 56 Gbps PAM4, making it suitable for high-speed signal applications such as PCIe, Ethernet, and other protocols. The operating temperature range is -55°C to +125°C, and the insulator is made from liquid crystal polymer (LCP) with copper alloy contacts plated with 0.76µm gold.

 

The connector is designed for surface mount assembly and is provided in tape and reel packaging for automated manufacturing. It features board guide and pick-and-place options for ease of assembly. Mated stacking heights of 7mm and 10mm are supported, offering flexibility for mezzanine board-to-board interconnections.
