Frequently Asked Questions
What pitch and position count does the SFM-124-L2-L-D-A-K-TR provide for board-to-board connections?
The SFM-124-L2-L-D-A-K-TR features 48 positions in a dual-row arrangement with a 0.050 inch (1.27 mm) pitch, providing 24 contacts per row. This ultra-fine pitch allows twice the connection density of standard 0.100 inch pitch connectors in the same board length, critical for compact mezzanine card and module-stacking designs.
How does the high-reliability rating of the SFM-124-L2-L-D-A-K-TR compare to standard SMT socket strips?
SAMTEC's SFM high-reliability socket strips are rated for thousands of mating cycles with gold-plated contacts that maintain low contact resistance over extended service life. Standard SMT socket strips often have shorter cycle ratings and thinner plating, making the SFM-124-L2-L-D-A-K-TR preferable for medical, military, and aerospace applications demanding exceptional connector durability.
Which mating connector series is compatible with the SFM-124-L2-L-D-A-K-TR socket strip?
The SFM-124-L2-L-D-A-K-TR is designed to mate with SAMTEC's SFM-series header strips at 0.050 inch pitch with 48 positions on a dual-row layout. The matched system provides a fully specified mating interface with defined insertion force and retention force, ensuring reliable board-to-board electrical connections in high-vibration or high-cycle-count environments.
