Key Features
- 44-position dual-row layout at 0.050-inch pitch delivering high signal density in a compact SMT footprint
- Tape-and-reel (TR) packaging enabling high-volume automated pick-and-place assembly for production efficiency
- Anti-mis-mating key (K) feature prevents incorrect connector orientation in dense 44-pin SMT assemblies
Applications
The SFM-122-T2-S-D-A-K-TR is used in mezzanine module interconnects, FPGA daughter boards, and compact embedded computing platforms where 44 signals must be routed across a 0.050-inch pitch surface-mount interface. Its tape-and-reel packaging supports high-volume production environments with automated SMT lines, reducing assembly cycle time. The dual-row format doubles pin density versus single-row alternatives, enabling more compact PCB layouts in space-constrained industrial and telecom equipment.

Frequently Asked Questions
How many positions does the SFM-122-T2-S-D-A-K-TR provide, and what pitch separates the contacts?
The SFM-122-T2-S-D-A-K-TR provides 44 positions in a dual-row configuration on a 0.050-inch (1.27 mm) pitch. This compact arrangement supports routing of 44 discrete signals or a mix of power and signal lines across a single mezzanine interface, reducing the number of connectors required on space-constrained PCBs in embedded computing and instrumentation designs.
What does the TR suffix mean for the SFM-122-T2-S-D-A-K-TR, and how does it benefit production assembly?
The TR suffix denotes tape-and-reel packaging, where connectors are supplied on a continuous carrier reel for automated pick-and-place SMT assembly. For a 44-pin surface-mount connector at 0.050-inch pitch, tape-and-reel delivery eliminates manual placement, reducing placement errors and improving throughput in high-volume PCB assembly lines by allowing reel-to-feeder integration with standard SMT equipment.
In which FPGA or module carrier board designs is the SFM-122-T2-S-D-A-K-TR typically specified?
The SFM-122-T2-S-D-A-K-TR is commonly specified on FPGA development boards, COM Express Type 6 carrier modules, and small form-factor embedded computer boards that use the SAMTEC SFM/SFS mating system to carry 44 mixed-signal connections at 0.050-inch pitch. The keying (K) feature prevents reverse insertion damage in prototype and field-service environments where connectors may be unmated and re-seated multiple times.
