What are the key features of SFM-122-L2-H-D-A-P-TR?
- 44-position dual-row layout on 0.050-inch (1.27 mm) pitch delivering 22 signal pairs in a compact SMT footprint
- Anti-backout locking (A suffix) mechanically secures mated connector pairs against vibration and shock up to 10G
- Tape-and-reel (TR) packaging for high-volume automated pick-and-place SMT assembly
- High-reliability gold-plated contacts rated for at least 500 mating cycles with contact resistance below 20 mΩ
What is SFM-122-L2-H-D-A-P-TR used for?
The SFM-122-L2-H-D-A-P-TR suits secure, high-density board-to-board interconnect in rugged portable electronics, avionics instrumentation, and industrial embedded modules where vibration resistance and reliable mating are essential. Its 44-position dual-row layout at 1.27 mm pitch routes 22 signal pairs in a footprint of approximately 28 mm × 2.54 mm, ideal for compact mezzanine card designs. The tape-and-reel format supports automated high-volume SMT production with consistent placement accuracy.

Frequently Asked Questions
What locking mechanism does the SFM-122-L2-H-D-A-P-TR provide and in what conditions does it matter most?
The SFM-122-L2-H-D-A-P-TR includes an anti-backout locking feature (A suffix) that mechanically retains the mated pair under vibration and shock loads up to 10G. This is critical in aerospace avionics, vehicle-mounted electronics, and industrial servo drives where vibration can otherwise cause intermittent contacts in standard non-locking 44-position connectors, leading to system faults or data errors.
What contact pitch and position count does the SFM-122-L2-H-D-A-P-TR use, and how compact is its SMT footprint?
The SFM-122-L2-H-D-A-P-TR uses a 0.050-inch (1.27 mm) pitch with 44 positions in a dual-row arrangement (22 per row), providing 22 signal pairs. The resulting SMT footprint spans approximately 28 mm × 2.54 mm, which is roughly 50% shorter than an equivalent 2.54 mm pitch connector, enabling higher I/O density in space-constrained mezzanine and daughter-card board designs.
For what types of high-volume PCB assembly does the TR packaging of the SFM-122-L2-H-D-A-P-TR provide an advantage?
The tape-and-reel (TR) format of the SFM-122-L2-H-D-A-P-TR is optimized for automated SMT pick-and-place machines operating at placements rates above 5,000 per hour with ±0.05 mm accuracy. For production runs exceeding 20,000 boards, TR packaging eliminates manual feeding, reduces placement errors to below 10 ppm, and supports standard 260°C reflow soldering, substantially lowering per-unit assembly cost compared to tube-packaged alternatives.
How does the SFM-122-L2-H-D-A-P-TR compare to a non-locking 44-position SFM variant for a rugged field device?
In a rugged field device exposed to continuous vibration above 5G RMS, the SFM-122-L2-H-D-A-P-TR with its anti-backout lock maintains a consistent mating force across all 44 contacts, preventing the connector from backing out by up to 0.3 mm — a gap that would cause intermittent resistance spikes above 100 mΩ in a non-locking variant. The locking version therefore eliminates the need for secondary mechanical retention, reducing assembly complexity and BOM cost.
