Key Features
- 0.050 inch (1.27 mm) pitch dual-row socket providing 12 positions in a compact SMT footprint for high-density board interconnects
- Gold (10 µin) over Nickel (50 µin) contact finish on mating surfaces ensuring low contact resistance and extended insertion cycle life
- Phosphor bronze contacts with polarized housing design preventing incorrect mating orientation and ensuring reliable signal integrity in high-reliability applications
Applications
The SAMTEC SFM-106-T2-L-D-A-K-TR is designed for high-reliability PCB-to-PCB and module-to-motherboard socket applications in aerospace, defense, medical equipment, and industrial control systems requiring consistent electrical performance over thousands of mating cycles. Its 0.050 inch pitch dual-row layout maximizes contact density for space-constrained designs such as daughter card interfaces and embedded module sockets. The gold-plated mating contacts and matte tin termination make it suitable for automated reflow assembly with demanding reliability requirements.

Frequently Asked Questions
What contact finish does SFM-106-T2-L-D-A-K-TR use and why does it matter for reliability?
The SFM-106-T2-L-D-A-K-TR uses Gold (10 µin) over Nickel (50 µin) on the mating contact surfaces and Matte Tin (Sn) with Nickel (Ni) barrier on the termination side. The gold mating finish provides low and stable contact resistance over many insertion cycles, while the nickel barrier prevents gold-tin intermetallic formation during reflow soldering, ensuring long-term reliability in high-cycle socket applications.
For which high-density board applications is SFM-106-T2-L-D-A-K-TR's 0.050 inch pitch most beneficial?
At 0.050 inch (1.27 mm) pitch with 2 rows of 6 contacts each, the SFM-106-T2-L-D-A-K-TR achieves twice the contact density of 0.100 inch pitch alternatives in the same board footprint. This makes it particularly valuable in FPGA daughter card interfaces, memory module sockets, RF front-end module connections, and compact instrument boards where 12 high-reliability contacts must fit within a few millimeters of PCB area.
How does the polarized housing of SFM-106-T2-L-D-A-K-TR prevent mating errors in production assembly?
The polarized socket housing of the SFM-106-T2-L-D-A-K-TR incorporates a keying feature that physically prevents incorrect 180-degree rotational mating with the corresponding header, eliminating the risk of damaged contacts or reversed signal connections. This is especially important in high-volume automated and manual assembly environments where a 12-position dual-row connector at 0.050 inch pitch can otherwise be difficult to visually orient correctly.
How does the phosphor bronze contact material in SFM-106-T2-L-D-A-K-TR compare to brass in SMT socket applications?
Phosphor bronze offers a higher yield strength and superior spring-back properties compared to brass, maintaining consistent contact normal force over repeated mating cycles and after thermal cycling between -55°C and +125°C. For a high-reliability socket like SFM-106-T2-L-D-A-K-TR, phosphor bronze contacts retain their clamping force longer, reducing contact resistance drift after hundreds of insertions that would cause brass contacts to relax and increase resistance above acceptable limits.
