What are the key features of SFM-123-L2-H-D-K-TR?
- 46-position dual-row SMT socket strip at ultra-fine 1.27 mm (0.050") pitch for space-critical high-density designs
- Polarization key (K) prevents mis-mating of 46-pin socket in multi-connector PCB layouts
- High standoff (H) variant provides additional clearance beneath the socket, accommodating components on opposing board face
What is SFM-123-L2-H-D-K-TR used for?
The SAMTEC SFM-123-L2-H-D-K-TR is designed for high-density, space-critical board-to-board mezzanine connections in medical devices, aerospace electronics, and high-performance computing modules. Its 1.27 mm pitch and 46-position layout provide a compact footprint where signal density is paramount. The polarization key and high standoff ensure reliable, keyed mating with sufficient inter-board clearance for populated opposing PCBs.

Frequently Asked Questions
What pitch and position count characterize the SFM-123-L2-H-D-K-TR, and why does this matter for high-density PCB designs?
The SFM-123-L2-H-D-K-TR features 46 positions at a 1.27 mm (0.050") pitch in a dual-row layout. This fine pitch enables twice the pin density compared to 2.54 mm connectors, critical for compact mezzanine boards in medical, aerospace, or portable computing applications.
How does the tall standoff (H) option on the SFM-123-L2-H-D-K-TR benefit board stacking configurations?
The high (H) standoff increases the inter-board gap, providing clearance for components mounted on the facing side of either PCB. For 46-position, 1.27 mm pitch mezzanine designs, this prevents physical interference between boards and allows taller SMT components such as capacitors or oscillators to be placed underneath.
Under what procurement lead-time scenarios should engineers consider the SFM-123-L2-H-D-K-TR in tape-and-reel format?
Engineers running continuous high-volume SMT lines should specify the tape-and-reel (TR) format for this 46-position, 1.27 mm pitch socket. Tape-and-reel reduces manual feeder changes and supports uninterrupted production runs, shortening per-board assembly cycle times when output quantities exceed several thousand units.
