Frequently Asked Questions
What is the contact pitch and pin count of the SFM-119-L2-H-D-A-K-TR socket strip?
SFM-119-L2-H-D-A-K-TR features 38 positions in a dual-row layout on a 0.050 inch (1.27 mm) pitch, providing 19 contacts per row. This compact pitch allows more signal density per inch of board edge compared to standard 0.100 inch connectors, making it well suited for high-density I/O interfaces on FPGA modules, communication daughter cards, and industrial control mezzanines.
What makes SFM-119-L2-H-D-A-K-TR a high-reliability connector, and which demanding environments is it designed for?
SFM-119-L2-H-D-A-K-TR uses SAMTEC's high-reliability construction with gold-plated contacts and robust retention force, tested to thousands of mating cycles without significant degradation in contact resistance. These characteristics meet requirements for defense, aerospace, and medical equipment where intermittent contact failure is unacceptable. The SMT footprint also withstands reflow soldering temperatures up to 260 degrees C, ensuring solder joint integrity in production.
How does the tape-and-reel packaging of SFM-119-L2-H-D-A-K-TR benefit automated PCB assembly?
The TR suffix indicates tape-and-reel packaging, which is compatible with standard pick-and-place machines using 8 mm or 12 mm carrier tape. Automated placement of each 38-position socket at 0.050 inch pitch ensures accurate positioning within ±0.1 mm, critical for reliable mating with the corresponding header. Reel quantities typically start at 500 or 1000 pieces, reducing changeover time in high-volume SMT production lines.
How does SFM-119-L2-H-D-A-K-TR compare to 0.100 inch pitch socket strips for signal-dense PCB designs?
At 0.050 inch (1.27 mm) pitch, SFM-119-L2-H-D-A-K-TR accommodates 38 contacts in roughly the same board length a 20-contact 0.100 inch strip would require, nearly doubling signal density per unit length. For a 19-row-per-side layout, the connector body spans approximately 1 inch versus 2 inches for an equivalent 0.100 inch dual-row part. This halved footprint is critical in compact embedded systems and small-form-factor modules.
