Key Features
- 56-position dual-row configuration on 0.050" (1.27 mm) pitch for high-density board interconnects
- High-reliability socket design with surface mount termination for secure PCB attachment
- Dual-row layout enables compact 28x2 contact arrangement reducing board footprint by up to 50% vs single-row
Applications
The SFM-128-L2-H-D-A is suited for high-density board-to-board and mezzanine connections in industrial control, medical instrumentation, and test equipment where 0.050" pitch spacing maximizes signal density. Its surface mount format simplifies automated PCB assembly while the dual-row configuration supports 56 independent signal or power contacts. These characteristics make it ideal for applications demanding reliable low-profile interconnects in space-constrained environments.

Frequently Asked Questions
How many contacts does the SFM-128-L2-H-D-A provide and how are they arranged?
The SFM-128-L2-H-D-A provides 56 contacts arranged in a dual-row (28x2) configuration on a 0.050" (1.27 mm) pitch. This layout delivers high signal density while maintaining a compact footprint suitable for surface mount PCB assembly.
Which PCB assembly method is compatible with the SFM-128-L2-H-D-A socket strip?
The SFM-128-L2-H-D-A uses surface mount termination, making it fully compatible with standard SMT reflow soldering processes. The 0.050" pitch and dual-row design allow placement by automated pick-and-place equipment, streamlining high-volume production with 56 contacts per connector.
When would an engineer choose the SFM-128-L2-H-D-A over a single-row socket strip of similar pitch?
Engineers select the dual-row SFM-128-L2-H-D-A when board real estate is limited but 56 contacts are required, since the 28x2 arrangement provides twice the density of a single-row 0.050" strip. Applications in medical devices, industrial test equipment, and mezzanine card interconnects benefit from this compact high-reliability socket.
