What are the key features of SFM-104-02-FM-D-A-P-TR?
- 8-position dual-row 2×4 configuration on 0.050" (1.27 mm) pitch for ultra-compact board-to-board interconnect
- Flush-mount (FM) hardware variant minimizing overall mated height for thin-stack board assemblies
- High-reliability socket construction with gold-plated contacts for low contact resistance and extended insertion cycles
- Tape-and-reel (TR) packaging enabling automated SMT pick-and-place at 260 °C lead-free reflow compatibility
What is SFM-104-02-FM-D-A-P-TR used for?
The SFM-104-02-FM-D-A-P-TR is ideal for miniaturized sensor modules, wearable medical devices, and small avionics daughtercards where an 8-contact 0.050" pitch socket must mate with a corresponding header while keeping the board stack height as low as possible. Its flush-mount hardware allows the boards to sit nearly flush against each other, minimizing the mated assembly height to under 4 mm for space-critical enclosures. High-reliability gold-plated contacts ensure consistent performance over thousands of mating cycles in vibration-prone or thermally cycled environments.

Frequently Asked Questions
How many contacts does the SFM-104-02-FM-D-A-P-TR provide, and what is the significance of the 0.050" pitch for compact PCB designs?
The SFM-104-02-FM-D-A-P-TR provides 8 contacts in a 2×4 dual-row layout on a 0.050" (1.27 mm) pitch. At this pitch, the full connector footprint spans only about 5 mm in length, which is roughly half the board space consumed by an equivalent 0.100" pitch connector, enabling use in miniaturized PCBs for wearable electronics, hearing-aid modules, and small avionics sensors where every square millimeter of board area is critical.
What does the flush-mount (FM) hardware feature mean for the mated board stack height?
The FM designation indicates that the SFM-104-02-FM-D-A-P-TR uses flush-mount hardware that allows the mated PCBs to sit as close together as mechanically possible, typically achieving a board-to-board separation of 2 mm or less. This is significantly lower than standard stacking hardware variants that add 4 mm to 8 mm of separation, making the FM variant essential for ultra-thin assemblies such as smartwatch modules, miniature data loggers, and compact military electronics where total device thickness must be kept under 10 mm.
Is the SFM-104-02-FM-D-A-P-TR qualified for high-reliability or repeated-cycle applications such as removable plug-in modules?
Yes. SAMTEC's SFM high-reliability series is engineered for extended mating cycles, typically rated at 50 to 100 insertion/withdrawal cycles without significant degradation of contact resistance. Gold-plated contacts maintain resistance below 20 mΩ per contact, and the series is designed to operate from -55 °C to +125 °C, making this 8-pin socket suitable for hot-swap plug-in sensor cartridges, removable avionics modules, and field-replaceable industrial measurement units.
For a low-volume prototype run versus a high-volume production run, how does the TR packaging of the SFM-104-02-FM-D-A-P-TR affect procurement strategy?
For high-volume production of 500 to 5,000 boards, the tape-and-reel format is preferred because it feeds automated pick-and-place machines without manual handling, reducing placement error rates and enabling throughput of thousands of parts per hour. For low-volume prototypes of 10 to 50 pieces, minimum reel quantities (often 100 pieces) may be more than needed, so engineers sometimes order cut-tape alternatives or single-reel minimums from distributors to avoid excess inventory, especially given the small 8-pin format and relatively low per-unit cost.
