Key Features
- 44-position dual-row socket at 0.050 inch (1.27 mm) fine pitch enables high-density SMT board-to-board interconnect in compact PCB designs
- Floating mount (FM) termination accommodates PCB-to-PCB misalignment of up to ±0.5 mm, reducing mechanical stress on solder joints during mating
- High-reliability SFM series construction ensures consistent contact integrity across many mating cycles for aerospace, defense, and industrial applications
Applications
The SFM-122-02-FM-D-A-K is used in high-density board-to-board interconnects for industrial controllers, FPGA mezzanine modules, and aerospace avionics boards where 44 contacts at 0.050 inch pitch must fit within a minimal PCB area. Its floating mount feature compensates for PCB-to-PCB misalignment in stacked board assemblies, making it reliable in vibration-prone environments such as defense electronics and factory automation equipment. The dual-row format supports simultaneous routing of power and signal lines across 44 positions in a single compact connector.

Frequently Asked Questions
What is the contact count and pitch of the SFM-122-02-FM-D-A-K socket strip?
The SFM-122-02-FM-D-A-K features 44 positions in a dual-row arrangement at a fine 0.050 inch (1.27 mm) pitch, with 22 contacts per row. This high-density configuration allows routing of 44 signals in a footprint much smaller than an equivalent 0.100 inch pitch connector, making it well suited for compact multi-layer PCBs in embedded computing and communication modules.
How does the floating mount (FM) feature of SFM-122-02-FM-D-A-K help in stacked board designs?
The floating mount (FM) mechanism allows the connector body to shift laterally to accommodate PCB-to-PCB misalignment of typically ±0.3 mm to ±0.5 mm during mating. This is critical in stacked board assemblies where thermal expansion or mechanical tolerances across 44 contacts can cause stress on fine-pitch 0.050 inch solder joints if a rigid connector were used instead.
In what markets is the SFM-122-02-FM-D-A-K high-reliability socket strip used?
The SFM high-reliability series targets aerospace avionics, defense embedded computing, and industrial automation applications requiring proven connector reliability over extended service life. With 44 contacts at 0.050 inch pitch, the SFM-122-02-FM-D-A-K suits FPGA daughtercard interconnects, satellite subsystem boards, and ruggedized military computing platforms where connectors must maintain low contact resistance under shock and vibration.
How does SFM-122-02-FM-D-A-K compare to a standard 44-position 0.100 inch pitch socket strip?
The SFM-122-02-FM-D-A-K at 0.050 inch pitch occupies roughly half the PCB length of an equivalent 44-position 0.100 inch pitch socket strip, freeing valuable board real estate in space-constrained designs. Additionally, the high-reliability construction and floating mount feature of the SFM series provide better performance under vibration and misalignment compared to standard board-level socket strips, justifying its use in demanding aerospace and defense applications.
