SEAM-50-01-S-04-2-RA-K-TR Description

Short technical summary and product information.

The Samtec SEAM-50-01-S-04-2-RA-K-TR is a high-density array header connector from the SEARAY series, designed for high-speed board-to-board applications. It offers 200 positions arranged in 4 rows at a 1.27mm (0.050") pitch, with a right-angle surface mount configuration. The connector uses the Edge Rate contact system, which provides robust signal integrity and supports data rates up to 56 Gbps PAM4.

 

Electrical ratings include a maximum current of 1.9A per pin (with 10 pins powered) and a voltage rating of 240 VAC / 339 VDC. The operating temperature range spans -55°C to +125°C, making it suitable for demanding environments. Contacts are gold-plated with 30µin (0.76µm) thickness over a copper alloy base, and the insulator is black LCP.

 

The connector includes features such as a board guide and pick-and-place pads for automated assembly. It is packaged in tape and reel with a standard quantity of 175 pieces per reel. The part is RoHS and REACH compliant, with an MSL rating of 1 (unlimited). This header is ideal for mezzanine, coplanar, and right-angle interconnects in telecom, networking, and data center equipment.
