What are the key features of SFM-112-02-H-D-A-K?
- 24 positions in a dual-row 0.050-inch (1.27mm) pitch layout for high-density SMT board-to-board connections
- High-reliability socket strip construction with gold-plated contacts for low insertion loss and extended mating cycle life
- Surface-mount termination style compatible with standard reflow soldering up to 260°C peak temperature
- Keying and retention features (A-K suffix) prevent incorrect mating and secure connector during vibration
What is SFM-112-02-H-D-A-K used for?
The SFM-112-02-H-D-A-K is used in high-density daughter-card-to-motherboard interconnects within embedded computing modules, FPGA evaluation boards, and industrial control systems where 1.27mm pitch saves board space versus 2mm alternatives. Its 24-position dual-row format suits signal-intensive interface buses requiring 24 lines such as parallel data buses, address lines, or mixed signal-and-power connections. The high-reliability rating also makes it suitable for military, aerospace, and test-and-measurement equipment operating under mechanical shock and vibration conditions.

Frequently Asked Questions
How does the 0.050-inch pitch of the SFM-112-02-H-D-A-K compare to 0.100-inch pitch connectors for PCB space savings?
The SFM-112-02-H-D-A-K uses a 1.27mm (0.050-inch) pitch, providing 24 positions in approximately the same board length as only 12 positions on a 2.54mm (0.100-inch) pitch connector. This halves the PCB footprint for the same pin count, which is critical in compact embedded modules and mezzanine card designs with less than 100 mm² of connector area available.
Which high-cycle mating applications are best served by the SFM-112-02-H-D-A-K socket strip?
The SFM-112-02-H-D-A-K is rated for high-reliability service in applications requiring 500 or more mating cycles, such as test-and-measurement fixtures, lab prototype boards, and field-replaceable module bays in industrial controllers. Gold-plated contacts maintain under 30mΩ contact resistance across the rated cycle life, ensuring consistent signal integrity on 24-position dual-row interfaces.
Does the keying feature on the SFM-112-02-H-D-A-K prevent incorrect board insertion in multi-connector assemblies?
Yes, the A-K suffix denotes both the contact style and a mechanical polarization key. The keying tab physically blocks mating with un-keyed or incorrectly oriented headers, preventing mis-insertion on assemblies using multiple 24-position dual-row connectors at 1.27mm pitch. This is particularly valuable in field-service scenarios where 2 or more identical connectors sit within 10mm of each other.
What are the reflow soldering requirements for assembling the SFM-112-02-H-D-A-K on a PCB?
The SFM-112-02-H-D-A-K is designed for standard SMT reflow soldering with a peak temperature of up to 260°C per IPC/JEDEC J-STD-020. Its 24 SMT pads require a stencil aperture matched to 1.27mm pitch footprint guidelines, and a board warpage of less than 0.5mm over the connector length is recommended to achieve all 24 solder joints simultaneously.
