Frequently Asked Questions
How many positions and rows does the SFM-126-T2-STL-D-A-K-TR provide, and what is its pin pitch?
The SFM-126-T2-STL-D-A-K-TR provides 52 positions arranged in 2 rows at a 0.050-inch (1.27 mm) pitch. This high-density configuration supports up to 52 signal contacts in a compact surface-mount footprint, making it ideal for mezzanine and board-to-board interconnect designs with limited PCB space.
What retention mechanism does SFM-126-T2-STL-D-A-K-TR use to improve mechanical reliability?
The SFM-126-T2-STL-D-A-K-TR uses a stainless steel tail lock mechanism that secures the connector to the PCB surface, providing enhanced pull strength and vibration resistance. This feature is critical for applications experiencing mechanical shock or continuous vibration, such as industrial automation and aerospace equipment.
Which SAMTEC connector series is compatible with the SFM-126-T2-STL-D-A-K-TR for mating?
The SFM-126-T2-STL-D-A-K-TR is part of SAMTEC's SFM socket strip series, designed to mate with corresponding SAMTEC SFM or TFM series plug strips at 0.050-inch pitch. This matched connector family ensures reliable 52-pin electrical continuity and consistent mating force across the full 2-row contact array.
For what PCB assembly method is SFM-126-T2-STL-D-A-K-TR optimized?
The SFM-126-T2-STL-D-A-K-TR is optimized for surface-mount technology (SMT) assembly, allowing placement and reflow soldering in standard automated production lines. Its SMT termination style eliminates through-hole drilling, reducing board layer count requirements and enabling higher routing density on 4-layer or 6-layer PCB designs.
