What are the key features of SFM-105-02-FM-D-A-P?
- 10-position dual-row socket at 0.050 inch (1.27 mm) pitch enabling compact high-density board-to-board mating in space-constrained PCB designs
- Floating mount (FM) design providing ±0.5 mm positional tolerance compensation to accommodate PCB-to-PCB misalignment during mating
- Polarized (P) keying feature preventing incorrect connector orientation, protecting sensitive circuit connections in dual-rail power and signal applications
- High-reliability surface-mount construction rated for demanding aerospace and defense environments with low contact resistance and vibration resistance
What is SFM-105-02-FM-D-A-P used for?
SFM-105-02-FM-D-A-P is used in compact module-to-baseboard interconnects where a 10-position dual-row 1.27 mm pitch socket must accommodate slight PCB misalignment through its floating mount feature. It is well-suited for avionics LRU expansion connectors, rugged industrial SBC stackup boards, and miniaturized medical device modules that require secure polarized connections. The SMT footprint and automated-assembly compatibility make it popular in high-volume defense and instrumentation production lines.

Frequently Asked Questions
What does the floating mount (FM) designation mean for SFM-105-02-FM-D-A-P and how much misalignment does it tolerate?
The floating mount feature of SFM-105-02-FM-D-A-P allows the connector body to move laterally by approximately ±0.5 mm relative to the PCB footprint, compensating for board-to-board positional tolerances that accumulate in multi-board stacks, preventing mechanical stress on the 10 contacts and solder joints during mating and in-service vibration.
How many total signal positions does SFM-105-02-FM-D-A-P offer and what is its contact pitch?
SFM-105-02-FM-D-A-P provides 10 total positions arranged in a dual-row format with 5 contacts per row at a 0.050 inch (1.27 mm) pitch, offering a very compact high-density footprint roughly half the size of 2.54 mm pitch alternatives for the same signal count on tight PCB real estate.
What prevents incorrect mating of SFM-105-02-FM-D-A-P and why is polarity important in this application?
The polarized (P) suffix indicates a mechanical key feature on the connector housing that physically blocks 180-degree mis-insertion, ensuring all 10 signal and power contacts connect in the correct orientation; this is critical in dual-voltage board stacks where reversing the connector could apply 5 V to 3.3 V logic pins or reverse a power rail, causing immediate circuit damage.
Is SFM-105-02-FM-D-A-P compatible with standard reflow soldering processes and automated SMT assembly?
Yes, SFM-105-02-FM-D-A-P has surface-mount terminations rated for lead-free reflow soldering at peak temperatures up to 260°C per J-STD-020, and its body dimensions meet standard SMT pick-and-place nozzle requirements, enabling integration into automated assembly lines processing 1.27 mm pitch SMT components alongside 0402 and 0201 passives.
