Overview

The SFMC-120-02-L-D is a high-reliability, 40-position dual-row female socket connector designed for high-density board-to-board applications. It features a 1.27mm (0.050 inch) pitch and utilizes Tiger Eye Beryllium Copper (BeCu) contacts for superior durability and electrical performance. This surface-mount receptacle is part of Samtec's SFMC series, optimized for rugged environments requiring a low profile and reliable mating cycles.

Why Choose This Part

The use of Beryllium Copper (BeCu) contacts ensures high spring properties and long-term reliability over repeated mating cycles. Its 1.27mm pitch allows for a high pin count in a compact form factor, while the 10 micro-inch gold plating provides excellent corrosion resistance and electrical conductivity.

Applications

High-Density Board Stacking
Ideal for mezzanine card connections where vertical space is limited and a 1.27mm pitch is required to maintain a small PCB footprint.
Industrial Control Systems
Used in PLC and automation modules where Beryllium Copper contacts provide the mechanical resilience needed for vibration-prone environments.
Rugged Embedded Systems
Suited for military or industrial computing where a wide operating temperature range of -55C to +105C is essential.
Data Communication Equipment
Provides reliable signal integrity for multi-position interconnects in networking hardware and server peripherals.
