Key Features
- 4-position dual-row .050" (1.27 mm) fine-pitch high-reliability socket strip for compact SMT board-edge or mezzanine connections
- Straddle-mount (STL) termination style enables direct mounting on PCB edges, eliminating separate edge connector hardware
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT production for high-volume assembly efficiency
Applications
The SFM-102-L2-STL-D-A-K-TR is designed for compact board-edge and panel-mount interconnect applications in portable electronics, medical sensors, and wearable devices where space allows only a 4-pin .050" pitch connector footprint. Its straddle-mount termination style makes it suitable for PCB edge mating with flat-flex cables, daughter cards, or custom cable assemblies in miniaturized embedded designs.

Frequently Asked Questions
What is the straddle-mount termination style on the SFM-102-L2-STL-D-A-K-TR and how does it differ from standard SMT termination?
The straddle-mount (STL) termination style means the connector's solder tails wrap around and straddle the PCB edge, soldering to pads on both the top and bottom surfaces. Unlike standard surface mount connectors that solder only to the top layer, straddle mounting provides a mechanical grip on both board faces, increasing pull-out strength by several Newtons and enabling direct edge-to-cable or board-to-board mating at the PCB perimeter.
How many positions does the SFM-102-L2-STL-D-A-K-TR provide and what pitch does it use?
The SFM-102-L2-STL-D-A-K-TR provides 4 positions in a dual-row configuration with a .050" (1.27 mm) pitch, yielding 2 pins per row. Despite the small 4-pin count, the fine .050" pitch makes this connector extremely compact, occupying a board footprint of approximately 2.54 mm wide, suitable for the most space-constrained PCB edge connection scenarios.
When is the SFM-102-L2-STL-D-A-K-TR preferred over a standard through-hole edge connector for a miniaturized medical device design?
In a miniaturized medical device where board thickness is constrained to under 1.6 mm and PCB real estate is at a premium, the SFM-102-L2-STL-D-A-K-TR's straddle-mount SMT construction eliminates the need for a separate board-mounted housing and through-hole pins. The 4-pin .050" pitch footprint occupies under 5 mm of board edge length, enabling low-profile cable exits on disposable sensor cartridges and implantable monitor boards where every cubic millimeter matters.
