What are the key features of SFM-105-T2-FM-D-A-P?
- 10-position (2×5) dual-row layout at 0.050" (1.27 mm) pitch with floating-mount (FM) contact design that tolerates up to ±0.5 mm PCB misalignment for reliable board-to-board mating
- Contacts rated 1 A per pin and operating temperature to 150°C ensure signal integrity and long service life in industrial, rugged, and high-reliability computing applications
- Alignment peg (A) and polarisation (P) features prevent mis-insertion and ensure correct orientation during automated or manual assembly of stacked PCB assemblies
What is SFM-105-T2-FM-D-A-P used for?
The SFM-105-T2-FM-D-A-P is designed for board-to-board mezzanine connections in compact embedded systems, sensor modules, and industrial interface cards where PCB-to-PCB parallelism cannot be guaranteed to tight tolerances. The floating-mount contacts absorb axial and lateral misalignment of up to ±0.5 mm, reducing mechanical stress on solder joints during thermal cycling. Its 10-position, 0.050" pitch format concentrates signal connections in a minimal PCB footprint for designs constrained by enclosure or weight limits.

Frequently Asked Questions
What does the FM (floating-mount) designation mean for SFM-105-T2-FM-D-A-P in a board stack where PCB parallelism varies?
The FM suffix indicates a floating-mount contact design that allows the connector body to shift laterally and axially by up to ±0.5 mm to compensate for PCB misalignment in a stacked assembly. This self-alignment reduces stress on the SMT solder joints during mating and thermal cycling, which is critical in 10-position 0.050" pitch assemblies where a small PCB warp could otherwise cause intermittent contact failures.
At what continuous current and maximum temperature is each contact of SFM-105-T2-FM-D-A-P rated?
Each of the 10 contacts in the SFM-105-T2-FM-D-A-P is rated at 1 A continuous current, and the connector operates across a temperature range up to 150°C. For mixed power-and-signal applications, grouping 2 adjacent contacts on a shared power rail should be limited to about 1.6 A total (0.8 A per contact) to stay within safe thermal margins in a fully loaded assembly.
How do the alignment peg (A) and polarisation (P) options of SFM-105-T2-FM-D-A-P prevent assembly errors?
The A suffix adds a mechanical alignment peg that registers the connector to a matching hole in the mating PCB, achieving positional accuracy within ±0.1 mm before solder reflow. The P suffix adds a polarisation feature that physically prevents the connector from being inserted in the wrong orientation, eliminating the risk of reversed connections on the 10-position 0.050" pitch socket during manual rework or automated assembly.
Which SAMTEC mating headers are designed to pair with SFM-105-T2-FM-D-A-P for a 10-position 0.050" board-to-board stack?
The SFM-105-T2-FM-D-A-P mates with SAMTEC's TFM and SHF series male headers at 0.050" (1.27 mm) pitch in the matching 2×5, 10-position configuration. Mating header post lengths typically range from 3 mm to 12 mm, and selecting the appropriate post length sets the board-to-board standoff distance to match the mechanical stack height required by the enclosure design.
