Key Features
- 92-position dual-row layout at 0.050" (1.27 mm) pitch providing 92 contact connections in a compact surface-mount footprint
- Low-profile L2 mating height variant minimizing stack height for thin board-to-board assemblies in height-constrained enclosures
- STL (straight latch) mechanical retention feature securing the mated connector pair against vibration and accidental unmating
- High-reliability gold-plated contacts with polarization key ensuring correct mating orientation and consistent low contact resistance
Applications
The SFM-146-L2-STL-D-A-K is designed for high-density 92-position board-to-board and mezzanine card interconnect applications in industrial computing, defense electronics, and telecommunications equipment where low stack height and mechanical retention are critical. Its straight latch feature and polarization key make it ideal for backplane and daughter-card assemblies in vibration-prone environments such as avionics and rail transportation systems. The surface-mount termination and compact 1.27 mm pitch also suit it well for high-layer-count PCBs in data center switch modules and FPGA accelerator boards requiring many reliable signal paths in a minimal footprint.

Frequently Asked Questions
How many contacts does the SFM-146-L2-STL-D-A-K provide and what is the row arrangement?
The SFM-146-L2-STL-D-A-K provides 92 positions arranged in 2 rows at a 0.050-inch (1.27 mm) pitch, delivering 92 independent signal contacts in a dual-row surface-mount format suitable for high-density board-to-board interconnect requirements in compact electronic systems.
What is the purpose of the STL (straight latch) feature on the SFM-146-L2-STL-D-A-K?
The STL straight latch is a mechanical retention mechanism integrated into the connector body that locks the mated pair together, preventing accidental unmating due to vibration or mechanical shock. This feature is particularly important in defense, avionics, and industrial automation applications where 92-position connectors must remain securely mated under dynamic load conditions.
In what board-to-board stack heights does the L2 variant of the SFM-146 series operate?
The L2 designation indicates a low-profile mating height, typically providing a reduced board-to-board separation compared to standard or tall variants, enabling thinner stack assemblies where enclosure height constraints limit the clearance between PCBs. This makes the SFM-146-L2-STL-D-A-K well suited for slim industrial modules and compact computing blades requiring 92-position connectivity at minimal stack height.
For a backplane assembly requiring resistance to vibration, why is the SFM-146-L2-STL-D-A-K a suitable choice?
The SFM-146-L2-STL-D-A-K combines a straight latch (STL) mechanical retention with high-reliability gold-plated contacts and a robust surface-mount housing, maintaining reliable 92-position electrical connectivity across operating temperatures from -55°C to +125°C and in environments subject to continuous vibration, such as rail, aerospace, and industrial machinery backplane assemblies.
