What are the key features of SFM-121-T2-L-D-K-TR?
- 42-position dual-row socket strip at 0.050" (1.27 mm) pitch delivering high-density board-to-board signal connectivity in a minimal footprint
- Right-angle (L) termination enabling board-edge mating direction for panel-accessible or card-edge connector configurations
- Gold-plated high-reliability contacts engineered for extended mating cycles and consistent low contact resistance in demanding environments
What is SFM-121-T2-L-D-K-TR used for?
The SFM-121-T2-L-D-K-TR is used in high-density right-angle board-to-board interconnect applications such as embedded module carriers, test and measurement instrumentation, and compact industrial controllers. Its 42-position dual-row 0.050" pitch design allows a large number of signals to cross a board-edge interface with minimal PCB footprint. The right-angle orientation is preferred when the mating connector must be accessible from the side of the assembled board rather than from above.

Frequently Asked Questions
How many contact positions and what pitch does the SFM-121-T2-L-D-K-TR provide?
The SFM-121-T2-L-D-K-TR provides 42 contact positions in a dual-row arrangement at 0.050" (1.27 mm) pitch, enabling a dense board-to-board signal interface within a compact surface mount footprint suitable for space-constrained embedded PCB designs.
For a compact embedded module design, how does the right-angle orientation of SFM-121-T2-L-D-K-TR help with enclosure accessibility?
The right-angle (L) tail bends the 42-position connector's mating face to the board edge so the mating header can be inserted parallel to the PCB surface. In enclosures where the board is mounted flat and a side panel must provide connector access, this 0.050" pitch right-angle configuration eliminates the need for a separate right-angle adapter or cable assembly.
When should an engineer choose SFM-121-T2-L-D-K-TR over the SFM-123-T2-LM-D-K-TR in the same product family?
SFM-121-T2-L-D-K-TR carries 42 positions while SFM-123-T2-LM-D-K-TR carries 46 positions, both at 0.050" pitch dual-row. Engineers select the 42-position variant when the interface requires 42 or fewer signal lines and the shorter connector fits the PCB layout better, while the 46-position SFM-123 is chosen when additional signals are needed without changing the pitch or row architecture.
