What are the key features of SFM-111-L2-L-D-A-K?
- 22-position dual-row socket strip on 0.050" (1.27 mm) pitch for compact high-density board-to-board signal routing
- L2 locking latch provides positive retention force to prevent unmating under vibration or mechanical shock
- Kinematic keying (K suffix) prevents mis-orientation during mating, reducing assembly errors in automated and manual builds
What is SFM-111-L2-L-D-A-K used for?
The SFM-111-L2-L-D-A-K is ideal for compact mezzanine board stacking in portable instruments, embedded module designs, and consumer electronics where a 22-position dual-row socket must stay mated under routine handling. Its 0.050" pitch minimizes board area while the L2 locking and kinematic keying combination simplifies field-replacement of daughter boards without risk of backward insertion. The surface mount termination integrates into standard reflow assembly processes up to 260°C peak.

Frequently Asked Questions
How does the L2 locking mechanism on SFM-111-L2-L-D-A-K prevent accidental unmating on a portable instrument with vibration?
The L2 locking latch on the SFM-111-L2-L-D-A-K requires a deliberate release force — typically above 5 N axial pull — before the 22-position dual-row connector separates. Without this latch, standard friction-fit 0.050" pitch SMT sockets may disengage under sustained vibration above 5 g, causing signal interruptions. The L2 mechanism is therefore specified for portable field instruments, ruggedized embedded modules, and handheld testers subject to drop or transit shock.
What board area does the 22-position SFM-111-L2-L-D-A-K occupy on a PCB compared to a 0.100" pitch equivalent?
The SFM-111-L2-L-D-A-K on 0.050" (1.27 mm) pitch spans 11 positions per row x 1.27 mm = approximately 14 mm per row, with a 2-row width of about 2.0 mm — giving a total footprint near 14 mm x 2 mm. A 0.100" (2.54 mm) pitch alternative for the same 22-position count would span approximately 28 mm per row, consuming twice the board length and requiring more than 55 mm² versus roughly 28 mm² for the SFM-111.
When mating the SFM-111-L2-L-D-A-K, which SAMTEC male header series is the correct counterpart?
The SFM-111-L2-L-D-A-K mates with SAMTEC's SFM-compatible vertical or right-angle male pin headers in the SFM or MEC series on the same 0.050" (1.27 mm) dual-row pitch. The kinematic keying (K suffix) on the socket requires the corresponding keyed male header — typically denoted by the K or matching A key in the male part number — ensuring proper polarization. For a 22-position socket, the matching male header carries 22 positions (11 per row) on 1.27 mm centers, with up to 0.5 A per contact signal rating.
