Key Features
- 32-position dual-row socket with 0.050-inch (1.27 mm) pitch for high-density board-to-board signal routing
- Surface-mount termination with kinematic mount option (K) for secure mechanical alignment during assembly
- High-reliability contact design supports repeated mating cycles in industrial and computing applications
- Compact SMT footprint enables module stacking with 16 contacts per row for efficient layout
Applications
The SFM-116-02-SM-D-A-K is designed for high-density mezzanine interconnects in embedded computing, FPGA daughter cards, and telecommunications hardware where 32 signal lines must be routed reliably across stacked PCBs. The kinematic mount feature provides mechanical alignment assistance during automated assembly, reducing misalignment risk in tight 0.050-inch pitch SMT placements. Industrial control modules and data acquisition boards also benefit from its dual-row layout and robust contact retention in vibration-prone environments.

Frequently Asked Questions
How many signal positions does the SFM-116-02-SM-D-A-K provide and what is its row configuration?
The SFM-116-02-SM-D-A-K provides 32 total positions in a dual-row format with 16 contacts per row, spaced at a 0.050-inch (1.27 mm) pitch, making it a compact surface-mount socket for high-density board-to-board signal interconnects.
What does the K suffix on SFM-116-02-SM-D-A-K indicate and how does it affect PCB assembly?
The K suffix on the SFM-116-02-SM-D-A-K designates a kinematic mount feature that provides mechanical alignment assistance during PCB assembly, improving placement accuracy at the 0.050-inch (1.27 mm) pitch and reducing the risk of misalignment in automated SMT production lines.
For an FPGA expansion card needing 30+ signal lines at sub-2 mm pitch, is SFM-116-02-SM-D-A-K appropriate?
Yes, the SFM-116-02-SM-D-A-K is well-suited for FPGA daughter cards requiring 32 signal lines at 0.050-inch (1.27 mm) pitch. Its dual-row SMT socket design accommodates high-speed signal routing with compact board space, and SAMTEC rates it for high-reliability mating cycles appropriate for modular computing platforms.
How does the 0.050-inch pitch of the SFM-116-02-SM-D-A-K compare to standard 0.100-inch pitch connectors in terms of PCB density?
The 0.050-inch (1.27 mm) pitch of the SFM-116-02-SM-D-A-K is half the spacing of standard 0.100-inch (2.54 mm) pitch connectors, allowing approximately 4 times the contact density per unit length. This means 32 contacts occupy roughly the same board length as 16 contacts would in a 2.54 mm pitch connector.
