What are the key features of SFM-112-T2-STL-D-K-TR?
- 24-position dual-row socket on 0.050 inch (1.27 mm) pitch enabling high-density signal interconnect in a compact fine-pitch SMT footprint
- STL (low-profile) body minimizes stack height above the PCB, critical for slim mezzanine assemblies and height-constrained enclosures
- T2 extended solder tail provides controlled stand-off for consistent solder joint height and improved automated optical inspection access
- Tape-and-reel (TR) packaging enabling continuous pick-and-place feeder operation for high-volume SMT manufacturing lines
What is SFM-112-T2-STL-D-K-TR used for?
The SFM-112-T2-STL-D-K-TR is designed for slim mezzanine and plug-in module designs where 24 signal or mixed-signal contacts must connect two stacked PCBs on a fine 0.050 inch pitch while maintaining a very low stack height above the board surface. It is well suited for compact IoT modules, wearable device sub-boards, and portable instrument expansion cards where the STL low-profile body minimizes enclosure thickness. Automated test equipment sockets, FPGA configuration headers, and small-form-factor compute modules with strict height budgets also benefit from this connector's combination of fine-pitch density and low-profile construction.

Frequently Asked Questions
What is the significance of the STL designation on the SFM-112-T2-STL-D-K-TR, and which board-stack height budgets does it enable?
STL indicates a low-profile body variant that reduces the above-board height of the connector compared to standard-height SFM socket strips. This allows designers to achieve board-to-board stack heights of approximately 2 mm to 4 mm—depending on the mating plug height selected—enabling ultra-slim mezzanine assemblies in wearable devices, compact handheld instruments, and miniature embedded modules where vertical space is constrained to under 5 mm.
For a 24-signal interface on a 0.050 inch pitch, how does the SFM-112-T2-STL-D-K-TR improve routing compared to a 0.100 inch pitch connector of the same position count?
The 0.050 inch (1.27 mm) pitch of the SFM-112-T2-STL-D-K-TR places 24 contacts in a linear length of approximately 14 mm for the dual-row arrangement, roughly half the 28 mm footprint of an equivalent 0.100 inch pitch connector. This halved footprint frees PCB edge space for signal routing, shields, or mounting hardware, and the finer pitch supports higher-speed signal fanout on boards with 100 µm or finer design rules.
How does the T2 solder tail of the SFM-112-T2-STL-D-K-TR affect reflow soldering on a fine-pitch 0.050 inch pad layout?
The T2 extended tail raises the connector body approximately 1.5 mm above the PCB surface after reflow, creating a consistent stand-off height across all 24 contact positions. On a fine 0.050 inch (1.27 mm) pitch where pad-to-pad spacing is tight, this clearance gives automated optical inspection cameras a viewing angle under the connector body to verify solder fillet formation and detect bridging defects without manual rework probing.
What tape-and-reel quantity considerations apply when sourcing the SFM-112-T2-STL-D-K-TR for production, and are cut-tape quantities available?
The TR suffix indicates tape-and-reel packaging, which typically ships in reel quantities of 500 to 2000 pieces at major distributors, optimized for automated SMT pick-and-place feeders. For development or low-volume runs requiring fewer than 100 pieces, cut-tape quantities are available from select authorized SAMTEC distributors, though minimum cut-tape fees may apply. Lead time for full reel orders is generally 1 to 5 business days from stock, while factory-direct orders can run 4 to 8 weeks.
