What are the key features of SFM-117-L2-SM-D-LC?
- 34-position dual-row SMT socket strip on 0.050" (1.27 mm) pitch enabling 34-signal board-to-board interfaces in a minimal PCB area
- Surface mount (SM) solder tail contact design facilitates reflow soldering and eliminates the need for PCB through-hole drilling
- High reliability gold-plated contacts provide stable low contact resistance for demanding telecom and industrial applications
- Dual-row layout delivers twice the signal density of a single-row strip in equivalent board length at 0.050" pitch
What is SFM-117-L2-SM-D-LC used for?
The SFM-117-L2-SM-D-LC is suited for high-density daughter-card sockets, mezzanine board interfaces, and module-to-backplane connections in telecommunications equipment, industrial control systems, and test instrumentation. Its 34-position dual-row configuration at 0.050" pitch provides a wide signal bus in a body length of approximately 21.59 mm, keeping the connector footprint compact. The high reliability contact rating makes it appropriate for systems requiring thousands of mating cycles and stable operation across extended temperature ranges.

Frequently Asked Questions
What is the total position count and physical length of the SFM-117-L2-SM-D-LC contact row?
The SFM-117-L2-SM-D-LC provides 34 total positions in a 2-row layout with 17 contacts per row on a 0.050" (1.27 mm) pitch. The contact row spans approximately 20.32 mm in length, making the connector compact enough for mezzanine board designs where the interface must fit within a 25 mm PCB width constraint while still accommodating 34 signal positions.
What distinguishes the SM (surface mount) solder tail variant of the SFM-117-L2-SM-D-LC from standard or long tail variants?
The SM designation on the SFM-117-L2-SM-D-LC refers to the surface mount solder tail geometry, optimized for SMT reflow soldering directly onto PCB pads without through-hole vias. Compared to long-tail (STL) or standard-tail variants, the SM tail provides a lower connector profile and is specifically dimensioned for standard 0.050" pitch SMT land patterns, keeping the connector height as low as possible — typically under 4 mm above the PCB surface for the SFM series.
For which signal types and bus widths is the SFM-117-L2-SM-D-LC a well-matched interconnect solution?
The SFM-117-L2-SM-D-LC is well-matched for parallel bus interfaces requiring 32 to 34 signal lines, such as 32-bit data bus plus control signals on embedded processor daughter cards, or 34-channel analog sensor interfaces in industrial data acquisition systems. Its high reliability gold-plated contacts are rated for signal levels up to the connector's current carrying capacity and support signaling rates compatible with sub-GHz digital interfaces at the 0.050" pitch geometry.
How does specifying the SFM-117-L2-SM-D-LC without the -TR suffix affect procurement and assembly planning?
Without the -TR (tape-and-reel) suffix, the SFM-117-L2-SM-D-LC is supplied in strip or tray packaging rather than on a continuous reel. This packaging is suitable for low-to-medium volume production or prototype assembly where manual or semi-automated SMT placement is used. For automated pick-and-place assembly producing more than 500 boards per shift, buyers should request the tape-and-reel variant to avoid feeder incompatibility and increased per-unit placement time associated with tray-fed connectors.
