Frequently Asked Questions
How many contacts does SFM-148-T2-L-D-A-K provide and how does this compare to other SFM series variants?
The SFM-148-T2-L-D-A-K provides 96 positions in a dual-row layout at 0.050" (1.27mm) pitch, making it the highest-pin-count variant in the SFM series for this pitch family. Compared to the SFM-145 with 90 pins or the SFM-142 with 84 pins, it adds 6 to 12 additional contacts per mating pair, which is valuable for FPGA expansion interfaces and high-bandwidth interconnects.
What retention force does the K locking mechanism provide for SFM-148-T2-L-D-A-K in vibrating environments?
The K suffix locking mechanism on SFM-148-T2-L-D-A-K provides a positive mechanical lock that requires intentional manual force to unmate, offering significantly higher retention than friction-only socket strips. This makes the connector suitable for applications rated to MIL-STD-810 vibration profiles or industrial shock levels, ensuring the 96-pin interface remains mated throughout the product lifetime.
For a high-density FPGA mezzanine card needing 96 I/O lines, is SFM-148-T2-L-D-A-K compatible with standard FMC footprints?
The SFM-148-T2-L-D-A-K at 0.050" (1.27mm) pitch with 96 positions is compatible with high-pin-count FMC (FPGA Mezzanine Card) and similar mezzanine interconnect standards. Its gold-plated contacts rated at 1A per pin support both high-speed differential signal pairs and auxiliary power routing across the 96-position dual-row footprint commonly used in VITA 57.1 FMC designs.
