Key Features
- 44-position dual-row socket at 0.050" (1.27 mm) pitch for compact 22-pair signal routing
- Right-angle A-P configuration enables horizontal board-edge mating in tight vertical clearance enclosures
- Tape and reel packaging supports high-volume automated pick-and-place assembly at production speeds
Applications
The SFM-122-L2-S-D-A-P-TR is designed for edge-mating applications in portable instruments, plug-in expansion boards, and compact data acquisition modules where vertical clearance above the PCB is restricted. Its 44-position right-angle layout at 0.050" pitch provides 22 signal pairs accessible from the board edge. High-volume manufacturing applications benefit from the tape-and-reel packaging for automated SMT placement.

Frequently Asked Questions
In which board assemblies does the right-angle orientation of SFM-122-L2-S-D-A-P-TR provide the most benefit?
The A-P right-angle orientation of the SFM-122-L2-S-D-A-P-TR is most beneficial in plug-in daughter board assemblies and stacked card configurations where vertical clearance above the board is less than 8 mm. The 44-position connector mates horizontally, allowing insertion from the PCB edge without requiring vertical access space above the 0.050" pitch socket rows.
What mating cycle rating and contact resistance spec apply to the SFM-122-L2-S-D-A-P-TR?
The SFM-122-L2-S-D-A-P-TR is rated for a minimum of 1000 mating cycles with gold-plated contacts maintaining contact resistance below 20 milliohms throughout the rated life. This ensures stable signal integrity across all 44 positions at 0.050" pitch in applications requiring frequent connector engagement such as test fixtures and field-replaceable modules.
How does the SFM-122-L2-S-D-A-P-TR compare to a 44-pin flat flexible cable (FFC) connector for a portable device redesign?
The SFM-122-L2-S-D-A-P-TR provides a more mechanically robust connection than typical FFC connectors, with 1000+ mating cycles versus 30 to 50 cycles for most FFC ZIF sockets. Its 0.050" pitch dual-row design supports 1 A per pin versus 0.3 A typical for thin FFC, making it superior for portable devices requiring both signal and light power distribution across 44 contacts.
