What are the key features of SFM-111-L2-SM-D-LC-TR?
- 22-position dual-row configuration with 0.050" (1.27 mm) pitch for compact, high-density PCB board-to-board interconnects
- Low-contact-force (LC) design reduces insertion and extraction force, protecting delicate 0.050" pitch mating pins during assembly
- Semi-mate (SM) feature provides a two-stage mating action with audible tactile confirmation of partial and full engagement
- Tape-and-reel (TR) packaging enables automated SMT pick-and-place assembly for high-volume PCB production workflows
What is SFM-111-L2-SM-D-LC-TR used for?
The SFM-111-L2-SM-D-LC-TR is suited for modular embedded systems, RF test fixtures, and FPGA daughter cards where a 22-position 0.050" pitch socket must be reliably mated and un-mated without damaging fine-pitch contacts. The semi-mate (SM) feature is valuable in field-serviceable equipment where operators insert modules by feel rather than by sight, providing haptic feedback at the 50% and 100% mating stages. Its SMT tape-and-reel format integrates directly into automated assembly lines for industrial and telecommunications PCBs.

Frequently Asked Questions
What is the semi-mate (SM) feature on the SFM-111-L2-SM-D-LC-TR, and how does it benefit field service operations?
The semi-mate (SM) feature provides a two-stage mating action where the connector locks at a partial engagement position and then fully mates with additional force; this gives technicians audible and tactile confirmation of both partial and full mating at 0.050" pitch, reducing the risk of incomplete connections in field-serviced equipment with restricted visual access.
How does the low-contact-force (LC) design of the SFM-111-L2-SM-D-LC-TR reduce wear on mating pins?
The LC (low-contact-force) contact geometry reduces the insertion and extraction force per pin by approximately 50% compared to standard-force versions; across 22 positions at 0.050" pitch, this reduces cumulative mating force significantly, extending pin and socket life well beyond 100 mating cycles in test fixture and modular board applications.
What total contact count and row arrangement does the SFM-111-L2-SM-D-LC-TR provide?
The SFM-111-L2-SM-D-LC-TR has 22 total positions in a dual-row layout with 11 contacts per row at a 0.050" (1.27 mm) pitch, occupying a footprint of approximately 0.55" by 0.10" on the PCB, making it one of the more compact dual-row options in the SAMTEC SFM family.
What is the advantage of choosing the SAMTEC SFM-111-L2-SM-D-LC-TR over a standard-force version for FPGA module interfaces?
For FPGA module interfaces that are frequently swapped during prototyping or evaluation, the LC low-contact-force variant reduces the cumulative stress on the 0.050" pitch gold-plated contacts; combined with SM semi-mate locking, it also prevents accidental partial ejection from vibration, maintaining signal integrity across all 22 positions in high-speed interfaces operating above 1 Gbps.
