Key Features
- 100-position dual-row SMT socket strip at 0.050 inch (1.27 mm) pitch for ultra-high-density interconnection
- Gold (10 µin) over nickel (50 µin) mating contacts on beryllium copper for high reliability and long contact cycle life
- Polarized housing design preventing mis-mating and ensuring correct orientation in high-pin-count assembly
Applications
The SFM-150-02-LM-D-A-K is designed for high-density board-to-board and board-to-module interconnects in applications demanding 100 signal connections at a compact 1.27 mm pitch. It is widely used in high-reliability computing platforms, telecommunications line cards, and advanced embedded systems where beryllium copper contacts and gold plating ensure consistent performance over many mating cycles. The polarized SMT socket format simplifies assembly and prevents errors during high-volume production.

Frequently Asked Questions
What contact material and plating does SFM-150-02-LM-D-A-K use, and why does it matter for reliability?
The SFM-150-02-LM-D-A-K uses beryllium copper contacts with gold (10 µin) over nickel (50 µin) plating on the mating interface. Beryllium copper provides superior spring force retention across thousands of mating cycles, while the gold over nickel finish resists oxidation and maintains low contact resistance — critical for 100-position high-reliability socket strips in demanding environments.
How does the 0.050 inch pitch of SFM-150-02-LM-D-A-K enable miniaturized system designs?
At 0.050 inch (1.27 mm) pitch, the SFM-150-02-LM-D-A-K achieves twice the contact density of standard 2.54 mm pitch connectors, fitting 100 positions into a significantly smaller PCB footprint. This enables designers to route 100 signals between boards or modules in systems where PCB area is constrained, such as compact embedded computing, telecommunications line cards, and modular test equipment.
What role does the polarization feature play when assembling boards with SFM-150-02-LM-D-A-K?
The polarized housing on SFM-150-02-LM-D-A-K physically prevents incorrect orientation during mating, which is especially important for a 100-position dual-row socket at 1.27 mm pitch where reversed insertion is not visually obvious. This mechanical keying feature eliminates mis-mating errors on assembly lines, protecting both the connector and the mating header from damage.
