Key Features
- 100-position dual-row socket strip with 0.050-inch (1.27 mm) pitch delivering maximum interconnect density in 2.655-inch body length
- Split board lock (STL) mounting feature providing mechanical retention strength to prevent connector lift-off during thermal cycling and vibration
- High-reliability female contact design with tin/lead over nickel barrier termination for robust solder joint integrity
- Surface mount board connector configuration enabling automated placement and reflow soldering in high-volume PCB production lines
Applications
The SFM-150-02-STL-D-LC is optimized for high pin-count board-to-board connections in FPGA carrier boards, server backplane modules, and complex industrial computing platforms requiring 100 positions in a compact 2.655-inch footprint. The split board lock feature ensures mechanical stability in environments subject to vibration or repeated thermal cycling, making it suitable for defense, aerospace, and industrial automation equipment. This socket strip supports parallel bus architectures, high-speed data interfaces, and multi-channel signal routing where pin density and reliability are critical.

Frequently Asked Questions
What mechanical advantage does the split board lock (STL) feature provide on the SFM-150-02-STL-D-LC?
The split board lock (STL) on SFM-150-02-STL-D-LC provides mechanical anchoring to the PCB through additional through-board retention pins, resisting connector lift-off forces up to several Newtons during thermal cycling between -55°C and +125°C. This is critical for 100-position connectors where uneven thermal expansion could cause solder joint fatigue without additional mechanical retention.
How many signals can the SFM-150-02-STL-D-LC route within its 2.655-inch body length at 0.050-inch pitch?
The SFM-150-02-STL-D-LC accommodates 100 signal positions in a 2.655-inch (67.4 mm) body length using a dual-row configuration at 0.050-inch (1.27 mm) pitch, with 50 positions per row. This gives a signal density of approximately 37.7 positions per inch, compared to roughly 18.9 positions per inch achievable at 0.100-inch pitch, making it ideal for FPGA and processor interface boards.
Which SAMTEC plug series is compatible for mating with SFM-150-02-STL-D-LC in board stacking designs?
The SFM-150-02-STL-D-LC mates with SAMTEC's TSM and SSM series terminal strips at 0.050-inch pitch, providing reliable board-to-board mating across all 100 positions with dual-row engagement. The mating stack height depends on the selected TSM or SSM plug variant, typically ranging from 5 mm to over 20 mm to accommodate various PCB-to-PCB spacing requirements.
For a high-channel-count data acquisition system needing over 80 analog inputs, why is SFM-150-02-STL-D-LC a practical interconnect solution?
The SFM-150-02-STL-D-LC provides 100 positions in a single 2.655-inch surface mount connector, sufficient to carry 80 or more analog input channels plus dedicated power, ground, and control signals. Using a single 100-position connector rather than multiple smaller connectors reduces board assembly steps, minimizes inter-connector skew across channels, and consolidates the 0.050-inch pitch footprint into one compact 2.655-inch by 0.19-inch area.
