Key Features
- 62-position dual-row layout with 0.050" (1.27 mm) pitch delivers 124 total contact positions for high-density board-to-board signal interconnects in a compact SMT footprint
- Gold-plated contacts rated at 1.0 A per contact and tested across -55°C to +125°C ensure reliable mating performance in harsh aerospace and defense environments
- Surface-mount termination enables automated pick-and-place assembly, reducing labor cost versus through-hole connector alternatives
Applications
The SFM-131-02-STL-D-A-K targets high-density mezzanine and backplane interconnect designs in aerospace, defense, and high-reliability industrial electronics where 62 positions are required in a tight 0.050" pitch layout. Its surface-mount termination supports automated assembly processes, reducing production cost and improving placement accuracy on multilayer PCBs. The dual-row configuration maximizes signal density per unit board length, making it ideal for compact FPGA daughter cards and data acquisition modules.

Frequently Asked Questions
How many contact positions does the SFM-131-02-STL-D-A-K provide and what current is each rated for?
The SFM-131-02-STL-D-A-K provides 62 positions in a dual-row layout — totaling 124 contacts — with each contact rated at 1.0 A, making it suitable for mixed signal and low-power supply distribution on dense daughter cards and mezzanine modules.
For a high-density FPGA mezzanine board, how does the 0.050" pitch of the SFM-131-02-STL-D-A-K compare to wider-pitch alternatives?
The 0.050" (1.27 mm) pitch of the SFM-131-02-STL-D-A-K delivers 62 positions in roughly the same board length that a 0.100" pitch connector would use for only 31 positions, effectively doubling signal density and enabling FPGA I/O expansion cards and DSP mezzanines with 100+ signal lines in a compact footprint.
Which thermal environments can the SFM-131-02-STL-D-A-K withstand, and why does this matter for aerospace applications?
The SFM-131-02-STL-D-A-K is rated for -55°C to +125°C operating temperature, meeting the thermal requirements of airborne and ground-based military electronics standards such as MIL-STD-810, where equipment must survive cold soak and high-temperature operation without connector derating or intermittent contact resistance.
