Key Features
- 48-position dual-row configuration at 0.050" (1.27 mm) pitch enables high-channel-count board-to-board signal routing in a compact footprint
- Surface-mount termination with tape-and-reel (TR) packaging supports automated high-volume SMT pick-and-place assembly
- Gold-plated contacts with kinematic (K) retention provide low contact resistance and secure mating engagement across 200+ cycles
Applications
The SFM-124-02-F-D-A-K-TR is designed for high-density mezzanine interconnect applications in networking line cards, FPGA development boards, and industrial control systems where 48 signals must be routed reliably between stacked PCBs at 0.050" pitch. Its surface-mount footprint and tape-and-reel packaging enable seamless integration into automated SMT assembly processes for high-volume production.

Frequently Asked Questions
How many signal channels can the SFM-124-02-F-D-A-K-TR carry and at what current rating per contact?
The SFM-124-02-F-D-A-K-TR supports 48 signal positions arranged in a dual-row format with 24 contacts per row at 0.050" (1.27 mm) pitch. Each gold-plated contact is rated for 1 A continuous current, supporting mixed signal and low-power routing in high-channel-count mezzanine interconnect assemblies.
What retention mechanism does the K option provide in the SFM-124-02-F-D-A-K-TR, and why does it matter for industrial designs?
The K option adds a kinematic locking feature that secures the mated connector pair against accidental unmating due to vibration or shock, making the SFM-124-02-F-D-A-K-TR suitable for industrial control, transportation, and ruggedized equipment environments. This retention system maintains reliable contact engagement across 200+ mating cycles without requiring additional mechanical hardware.
Which FPGA or processor board interconnect scenarios benefit most from the 48-position SFM-124-02-F-D-A-K-TR versus a lower-count SFM variant?
Designs routing 48 or more signal lines between an FPGA carrier board and a mezzanine daughtercard — such as high-speed serial interfaces, parallel bus expansions, or mixed GPIO/power rails — benefit from the SFM-124-02-F-D-A-K-TR because it consolidates all 48 connections into a single 0.050" pitch dual-row footprint. Lower-count SFM variants such as SFM-102 (4 positions) require multiple connectors to match the same channel density.
