Key Features
- 46-position dual-row socket at 0.050" (1.27 mm) pitch for ultra-high-density SMT signal routing
- High-reliability construction rated for demanding environments including military and aerospace applications
- Dual-row configuration provides 92 total contacts in a minimal PCB footprint
- Surface mount termination for stable solder joints compatible with standard SMT reflow processes
Applications
The SFM-123-L2-STL-D-A-K is engineered for high-reliability, high-density board-to-board and board-to-module interconnects in applications such as military electronics, aerospace systems, and high-performance computing modules. Its 0.050" pitch dual-row socket format enables designers to route 92 signals in a fraction of the space needed by standard 0.100" pitch connectors. Medical instrumentation and rugged industrial controllers also benefit from its reliable surface mount termination and compact 46-position dual-row design.

Frequently Asked Questions
How many contacts does the SFM-123-L2-STL-D-A-K provide, and what pitch does the connector use?
The SFM-123-L2-STL-D-A-K is a 46-position dual-row socket providing 92 total contacts at a 0.050" (1.27 mm) pitch, enabling extremely dense signal routing on compact SMT PCBs compared to standard 0.100" pitch alternatives.
For which high-reliability industries is the SFM-123-L2-STL-D-A-K particularly well suited?
Its high-reliability construction makes the SFM-123-L2-STL-D-A-K suitable for aerospace, military, and medical instrumentation, where connectors must maintain electrical contact integrity across temperature swings from -55°C to +125°C and mechanical shock environments.
What mounting method does the SFM-123-L2-STL-D-A-K use, and how does this affect manufacturing?
The SFM-123-L2-STL-D-A-K uses surface mount termination, allowing it to be placed by automated SMT pick-and-place machines and reflowed at standard profiles, integrating seamlessly into PCB assembly lines without requiring through-hole soldering operations.
How does the 0.050" pitch of the SFM-123-L2-STL-D-A-K compare to standard pitch connectors in terms of board space savings?
At 0.050" (1.27 mm) pitch, the SFM-123-L2-STL-D-A-K occupies approximately half the linear footprint of a 0.100" pitch 46-position socket, allowing designers to save several square centimeters of PCB area in dense multi-connector layouts.
