What are the key features of SFM-110-L2-STL-D-LC-TR?
- 20-position dual-row socket at 1.27 mm (0.050 inch) fine pitch for compact mezzanine and daughter card interconnects
- Straddle mount (STL) termination style enables direct PCB edge mounting without additional board supports or alignment hardware
- Low-profile (LC) housing minimizes above-board height for space-constrained stacking applications with tight Z-axis clearance
- Tape-and-reel (TR) packaging for automated SMT pick-and-place assembly on high-volume production lines
What is SFM-110-L2-STL-D-LC-TR used for?
The SFM-110-L2-STL-D-LC-TR is designed for PCB edge-mount and compact mezzanine applications in portable instrumentation, IoT modules, and embedded computing daughter cards where a low stacking height and fine 1.27 mm pitch are required. Its straddle mount termination style allows the connector to sit astride the PCB edge, enabling direct board-to-board connection without requiring a separate mounting header. The 20-position dual-row layout provides 20 contact points sufficient for moderate-complexity signal interfaces in space-constrained products.

Frequently Asked Questions
What does the straddle mount (STL) termination on the SFM-110-L2-STL-D-LC-TR enable that standard SMT termination cannot?
The straddle mount (STL) termination allows the SFM-110-L2-STL-D-LC-TR to be placed astride the edge of a PCB, with contact tails soldering to pads on both the top and bottom board surfaces simultaneously. This enables direct board-edge connections and can eliminate the need for a separate mating header or intermediate board, reducing the total part count and stacking height in PCB-to-PCB or module-to-carrier applications.
How does the low-profile (LC) housing height of SFM-110-L2-STL-D-LC-TR benefit compact IoT or wearable PCB designs?
The low-profile (LC) housing reduces the connector body height above the PCB surface to approximately 1.5 mm to 2.0 mm, minimizing the total Z-axis clearance required in the PCB stack. For IoT modules or wearable electronics where the entire assembly must fit within a few millimeters of vertical space, this low profile directly enables thinner enclosure designs while maintaining the 20-contact 1.27 mm pitch fine-pitch interconnect.
For a 20-position interface, when would SFM-110-L2-STL-D-LC-TR be selected over a larger position-count socket in the same SFM series?
SFM-110-L2-STL-D-LC-TR is selected when the interface requires exactly 20 contacts at 1.27 mm pitch, keeping the connector body length at approximately 12.7 mm (10 positions × 1.27 mm per row), which minimizes the board area consumed by the connector. Larger position-count sockets in the SFM series occupy proportionally more PCB real estate, so choosing the 20-position variant avoids wasting footprint on unused contacts in low-pin-count daughter card interfaces.
Does the tape-and-reel packaging of SFM-110-L2-STL-D-LC-TR support standard EIA-481 reel specifications for SMT assembly equipment?
Yes, SAMTEC tape-and-reel (TR) packaged connectors follow EIA-481 standards for carrier tape dimensions and reel diameter, ensuring compatibility with standard SMT pick-and-place feeders. The 20-position SFM straddle-mount socket is typically packaged on 7-inch or 13-inch reels, accommodating quantities from a few hundred to over 1000 pieces per reel, which aligns with typical high-volume production lot sizes for small-form-factor embedded modules.
