Frequently Asked Questions
How many positions and rows does the SFM-121-L2-H-D-A-K-TR connector provide, and at what pitch?
The SFM-121-L2-H-D-A-K-TR provides 42 positions arranged in a dual-row configuration at 0.050-inch (1.27mm) pitch. This layout delivers high signal density in a compact SMT footprint, making it suitable for mezzanine board stacking and daughter-card interconnects where routing space is limited and contact density is critical.
What makes the SFM-121-L2-H-D-A-K-TR suitable for high-reliability or mil-aero applications?
SAMTEC's SFM series is built for high mating cycle durability, with gold-plated contacts and robust socket construction designed to meet high-reliability interconnect standards. The SFM-121-L2-H-D-A-K-TR's dual-row 42-pin layout on a 0.050-inch pitch supports secure board-to-board connections in military, aerospace, and industrial test environments where connector integrity over hundreds of mating cycles is essential.
Does the tape-and-reel packaging of SFM-121-L2-H-D-A-K-TR support automated SMT assembly?
Yes, the TR (tape-and-reel) suffix on SFM-121-L2-H-D-A-K-TR indicates it is packaged for automated pick-and-place SMT assembly. This packaging format is compatible with standard reel sizes used in production SMT lines, enabling consistent placement of the 42-position 0.050-inch pitch socket strip at high throughput rates while minimizing handling errors in volume manufacturing.
