Key Features
- 34-position dual-row socket strip with ultra-fine 0.050-inch (1.27 mm) pitch for high-density PCB layouts
- High-reliability gold-plated contacts ensuring low contact resistance below 20 milliohms and long service life
- Surface mount design compatible with automated reflow soldering processes up to 260°C for efficient production
- Dual-row configuration doubling interconnect density compared to single-row solutions in the same board area
Applications
The SFM-117-02-L-D-A-K is ideal for high-density board-to-board mating applications in embedded computing, FPGA development boards, and compact industrial modules where 0.050-inch pitch enables maximum interconnect density. Its dual-row 34-position layout supports parallel data bus connections and multi-signal routing in space-constrained designs. This socket strip is also widely used in test fixtures, memory modules, and communications hardware requiring reliable, repeatable surface mount connections.

Frequently Asked Questions
How does the 0.050-inch pitch of the SFM-117-02-L-D-A-K benefit high-density PCB designs?
The SFM-117-02-L-D-A-K uses a 0.050-inch (1.27 mm) pitch, which is half the standard 0.100-inch pitch, allowing 34 positions in roughly the same board area as a 17-position standard connector. This ultra-fine pitch enables designers to route more signals in less than half the PCB real estate, critical for compact embedded computing and FPGA boards.
What reflow soldering temperature is the SFM-117-02-L-D-A-K rated for during SMT assembly?
The SFM-117-02-L-D-A-K is rated for surface mount reflow soldering at peak temperatures up to 260°C, compatible with standard lead-free SAC305 solder paste profiles. Its thermoplastic housing withstands typical reflow oven profiles with 30-second dwell times at peak temperature without dimensional distortion.
Which SAMTEC plug series mates with the SFM-117-02-L-D-A-K for board-to-board stacking applications?
The SFM-117-02-L-D-A-K from the SFM series mates with SAMTEC's TSM and SSM series plug strips at 0.050-inch pitch, providing reliable board-to-board mating with 34 positions and dual-row contact engagement. The mating interface supports stack heights from 4 mm to over 20 mm depending on the selected plug series.
For a data acquisition board needing 34 signal lines in minimal space, why choose SFM-117-02-L-D-A-K over a 0.100-inch pitch alternative?
Choosing the SFM-117-02-L-D-A-K at 0.050-inch pitch over a 0.100-inch alternative saves approximately 50% of connector footprint length while maintaining all 34 signal connections. A comparable 34-position connector at 0.100-inch pitch would require nearly double the PCB length, making the SFM-117-02-L-D-A-K the preferred solution for data acquisition boards, FPGA carriers, and any design prioritizing signal density over connector height.
