SS4-40-3.00-L-D-K-TR

Overview

The SS4-40-3.00-L-D-K-TR is a high-density, ultra-fine pitch board-to-board socket from Samtec's Razor Beam series. Featuring a 0.40mm pitch and 80 total positions across two rows, it is designed for space-constrained applications requiring reliable high-speed signal integrity. The connector includes an outer shroud for mechanical protection and a pick-and-place pad for automated SMT assembly.

Why Choose This Part

The Razor Beam system provides a ruggedized contact design with an undercut retention feature that increases unmating forces. With a 0.40mm pitch, it offers significant PCB space savings compared to standard 0.80mm or 1.27mm systems while maintaining a high durability rating of 100 mating cycles. The 10 micro-inch gold plating ensures low contact resistance and reliable performance in demanding environments.
