Key Features
- 56-position dual-row layout at 0.050" (1.27 mm) pitch supports dense signal routing in compact SMT designs
- Low-profile surface-mount termination enables automated reflow assembly without through-hole drilling
- High-reliability gold-plated contacts maintain low contact resistance over extended mating cycles for demanding interconnect applications
Applications
The SFM-128-T2-LM-D-A is designed for high-density board-to-board and mezzanine interconnect applications in embedded computing, telecommunications, and test-and-measurement equipment. Its 56-position, 1.27 mm pitch dual-row format allows engineers to route a large number of signals in a compact PCB footprint while maintaining reliable electrical performance. The surface-mount configuration integrates smoothly into automated SMT production lines and supports modular system architectures that require consistent, repeatable connector mating.

Frequently Asked Questions
How many positions and rows does the SFM-128-T2-LM-D-A provide?
The SFM-128-T2-LM-D-A is a 56-position, dual-row socket strip at 0.050" (1.27 mm) pitch, giving designers 28 positions per row. This configuration is ideal for dense signal routing in compact surface-mount PCB layouts where space is at a premium.
Can the SFM-128-T2-LM-D-A be assembled using standard SMT reflow soldering at 260°C peak?
Yes, the SFM-128-T2-LM-D-A is designed for surface-mount assembly and is compatible with standard SMT reflow profiles, including lead-free reflow at up to 260°C peak. Its 1.27 mm pitch footprint allows automated pick-and-place placement on standard 56-position dual-row SMT land patterns.
How does the 0.050" pitch of SFM-128-T2-LM-D-A compare to standard 0.100" pitch connectors for mezzanine boards?
The SFM-128-T2-LM-D-A's 0.050" (1.27 mm) pitch delivers twice the position density compared to 0.100" (2.54 mm) pitch connectors. For mezzanine designs needing 56 connections, this allows the connector footprint to occupy roughly half the PCB area, supporting more compact board stackups.
What kinds of systems typically use the SAMTEC SFM-128-T2-LM-D-A socket strip?
This 56-position, 1.27 mm pitch SMT socket strip is used in embedded computing modules, FPGA mezzanine cards, telecommunications line cards, and modular test equipment where reliable high-density board-to-board interconnects with repeatable 56-pin mating are required.
