What are the key features of SFM-124-T2-L-D-A-P-TR?
- 48-position dual-row SMT socket strip at 0.050" (1.27 mm) pitch delivers high signal density in a compact footprint suitable for FPGA mezzanine and processor module stacking
- Polarization peg (P) ensures correct orientation during mating, preventing pin-to-pin swap errors across 48 dual-row contacts in high-channel-count interfaces
- Tape-and-reel (TR) packaging supports automated SMT pick-and-place assembly, enabling consistent high-volume production with minimal manual handling
What is SFM-124-T2-L-D-A-P-TR used for?
The SFM-124-T2-L-D-A-P-TR is designed for board-to-board interconnect applications in FPGA mezzanine cards, processor daughterboards, and high-speed backplane modules that require 48 contacts at 0.050" pitch with reliable SMT attachment. The polarization peg and horizontal mating orientation make this socket particularly well suited for rugged military, telecom, and industrial computing systems where assembly errors must be eliminated and consistent signal routing across dozens of channels is critical.

Frequently Asked Questions
What is the function of the polarization peg (P) on the SFM-124-T2-L-D-A-P-TR, and why is it important for a 48-position connector?
The polarization peg is a mechanical feature on the connector body that mates with a corresponding hole in the mating header, ensuring the 48-position dual-row socket can only be inserted in the correct orientation. At 0.050" (1.27 mm) pitch with 48 contacts, even a single-pin offset would cross-connect adjacent signals, potentially corrupting high-speed data buses or applying incorrect voltages to sensitive ICs — the peg eliminates this failure mode entirely.
For a VITA-57 FPGA mezzanine card stack, how does the 0.050" pitch of the SFM-124-T2-L-D-A-P-TR compare to older 0.100" pitch socket options?
At 0.050" (1.27 mm) pitch, the SFM-124-T2-L-D-A-P-TR fits 48 positions into the same board length that a 0.100" pitch alternative would need for 24 positions. This halving of connector length frees significant PCB area on FPGA mezzanine cards for additional IO circuitry, decoupling networks, or high-speed signal routing layers, while maintaining 48 independent signal channels across the dual-row dual-board interface.
How does tape-and-reel (TR) packaging for the SFM-124-T2-L-D-A-P-TR benefit SMT production lines running high board volumes?
Tape-and-reel packaging feeds the SFM-124-T2-L-D-A-P-TR directly into SMT pick-and-place machines, eliminating the manual tray-loading step required for bulk or tube-packaged connectors. For a 48-position SMT socket with a polarization peg, automated placement ensures the peg and all contact tails land precisely on their designated PCB pads at 0.050" pitch, reducing placement rejects and improving solder joint yield across high-volume production runs.
In what scenario would a designer choose the SFM-124-T2-L-D-A-P-TR rather than two separate 24-position 0.050" socket strips for the same interface?
A single 48-position SFM-124-T2-L-D-A-P-TR is preferred over two 24-position strips when mechanical alignment between the two boards must be controlled at a single reference datum. Two separate connectors require independent pad alignment and can accumulate rotational and translational tolerance errors, whereas the single 48-contact dual-row body at 0.050" pitch maintains all 48 contacts in one precisely registered housing, reducing mating force variation and connector-induced signal skew.
