Overview

The SFM-120-02-S-D-LC-K-TR is a high-reliability Tiger Eye socket strip from Samtec featuring 40 total positions in a dual-row configuration. This 1.27mm (0.050 inch) pitch connector uses Beryllium Copper (BeCu) contacts with 30 micro-inches of selective gold plating, designed for rugged board-to-board or cable-to-board interconnects. The surface-mount design includes a locking clip and polyimide film pick-and-place pad for automated assembly.

Why Choose This Part

The Tiger Eye contact system is specifically engineered for high-cycle applications, providing superior spring properties and multi-finger contact points. The use of Beryllium Copper ensures long-term reliability and resistance to stress relaxation at elevated temperatures. This specific variant includes a locking clip for enhanced mechanical stability and a pick-and-place pad to streamline SMT production.

Applications

High-Reliability Board-to-Board Interconnects
Used to create secure, vibration-resistant connections between primary logic boards and daughtercards in industrial environments.
Rugged Embedded Systems
Ideal for compact embedded systems requiring high mating cycle durability and a wide operating temperature range from -55C to 125C.
Mezzanine Card Expansion
Facilitates stacking of PCB layers in space-constrained enclosures where a 1.27mm pitch is necessary to maintain signal density.
