Key Features
- 36-position dual-row surface mount socket strip at 0.050" (1.27 mm) pitch for compact, high-density PCB interconnections
- Gold-over-nickel contact finish provides low and stable contact resistance across thousands of mating cycles
- -K keying option prevents mis-mating in multi-connector assemblies, reducing assembly errors in production environments
Applications
The SFM-118-L2-SM-D-A-K is designed for high-density board-to-board and daughter-card interfaces in embedded computing, FPGA evaluation boards, and instrumentation modules. The keying feature makes it especially valuable in multi-connector PCB assemblies such as modular signal conditioning systems and test jig fixtures where incorrect mating must be prevented.

Frequently Asked Questions
What does the -K suffix indicate on the SFM-118-L2-SM-D-A-K and why does it matter for assembly?
The -K suffix denotes a keying feature that physically prevents incorrect mating with unkeyed or differently keyed connectors. In PCBs with multiple 36-position 0.050" pitch socket strips, this polarization ensures each connector mates only with its corresponding header, eliminating costly assembly errors and reducing field failures in multi-connector systems.
How many contacts per row does the SFM-118-L2-SM-D-A-K provide and what pitch does it use?
The SFM-118-L2-SM-D-A-K provides 18 contacts per row in a dual-row configuration for 36 total positions at 0.050" (1.27 mm) pitch. This fine-pitch layout enables high signal density in a small PCB footprint, making it suitable for compact embedded modules, daughtercards, and test and measurement equipment requiring reliable 36-pin interconnects.
Which signal types are most reliable when routed through the SFM-118-L2-SM-D-A-K at high frequencies?
The gold-over-nickel contact finish and tight 0.050" pitch geometry of the SFM-118-L2-SM-D-A-K support reliable transmission of digital signals up to several hundred MHz. The surface mount footprint minimizes stub length, benefiting differential pairs, LVDS, and single-ended logic signals used in FPGA interfaces, SPI buses, and parallel data paths in embedded systems.
Is the SFM-118-L2-SM-D-A-K suitable for automated SMT reflow assembly?
Yes, the SFM-118-L2-SM-D-A-K is designed for surface mount technology and is compatible with standard SMT reflow assembly processes. Its surface mount pads eliminate drilling requirements, and the component can be placed by automated pick-and-place machines, making it cost-effective for high-volume production runs with standard 36-position dual-row connector needs.
