What are the key features of SFM-150-02-LM-D-A-K-TR?
- 100-position dual-row layout on 0.050" (1.27 mm) pitch achieves maximum signal density for high-count board-to-board interconnects
- Low-profile LM (low mount) height option minimizes overall stacked PCB assembly thickness for compact enclosures
- Board-lock (K) feature provides mechanical retention to prevent connector lift under vibration or thermal cycling stress
- Tape-and-reel (TR) packaging supports automated SMT assembly for high-volume manufacturing with consistent placement
What is SFM-150-02-LM-D-A-K-TR used for?
The SFM-150-02-LM-D-A-K-TR is designed for high-density mezzanine and stacking applications in server blades, network switches, and FPGA evaluation boards requiring 100 or more signal connections in a constrained footprint. Its low-profile LM stackup height allows tightly spaced PCB pairs in space-critical chassis, while the board-lock pins secure the connector against mechanical stress during transport and operation. High-volume production environments benefit from the tape-and-reel format, which feeds automated pick-and-place lines without manual connector loading.

Frequently Asked Questions
How many positions does the SFM-150-02-LM-D-A-K-TR have, and how are they arranged on the PCB?
The SFM-150-02-LM-D-A-K-TR provides 100 positions arranged in a dual-row pattern on a 0.050-inch (1.27 mm) pitch. This high-density layout places 50 contacts per row, enabling 100 independent signal or power connections within a compact PCB footprint suitable for FPGA mezzanine cards, processor daughterboards, and high-bandwidth backplane modules.
What does the low-profile LM designation mean for stacked PCB assembly height?
The LM suffix on the SFM-150-02-LM-D-A-K-TR indicates a low-mount stacking height, which reduces the overall mated assembly height compared with standard-height SFM variants. This is critical in chassis-constrained designs such as 1U rack servers or embedded computing modules, where clearance between stacked PCBs may be as little as 3 mm to 5 mm.
Why is the board-lock (K) feature on the SFM-150-02-LM-D-A-K-TR important for industrial or ruggedized applications?
The K (board-lock) feature extends retention pegs from the connector body through the PCB, providing mechanical anchoring that resists axial pull-out forces and lateral displacement caused by vibration or thermal cycling. In industrial controllers or ruggedized avionics modules exposed to continuous vibration above 5 G, connectors without board locks can experience fretting corrosion and intermittent contact failures over time.
Which SAMTEC mating headers are compatible with the SFM-150-02-LM-D-A-K-TR for a board-stacking design?
The SFM-150-02-LM-D-A-K-TR mates with SAMTEC TFM and TSM series dual-row headers on the same 0.050-inch (1.27 mm) pitch with a matching 100-position count. These mating headers are available in stacking heights from approximately 2 mm to 20 mm, providing flexibility in selecting board separation to accommodate component heights and thermal management requirements in stacked PCB assemblies.
