Frequently Asked Questions
How many positions does the SFM-125-L2-L-D-A provide, and what row configuration does it use?
The SFM-125-L2-L-D-A is a dual-row connector with 25 positions per row, giving 50 total positions. The body measures 1.375 inches in length, supporting high-density board-to-board signal connections in compact PCB layouts.
What contact finish does the SFM-125-L2-L-D-A use, and why does it matter for reliability?
The connector uses a tin-over-nickel contact finish, which provides good corrosion resistance and maintains low contact resistance over multiple mating cycles. The Tiger Eye 4-point contact design further enhances reliability by distributing the normal force across 4 contact points, reducing the risk of intermittent connections in vibration-prone environments.
Which board mounting option does the SFM-125-L2-L-D-A include, and how does it help during PCB assembly?
This connector includes a positioning pin board mounting option. The positioning pin aligns the 1.375-inch body accurately to the PCB footprint during hand or automated placement, reducing misalignment risk and ensuring all 50 positions make proper contact after soldering.
What are typical applications for the SFM-125-L2-L-D-A in embedded or industrial designs?
The SFM-125-L2-L-D-A suits backplane interconnects, mezzanine card stacking, and module-to-baseboard connections in industrial controllers and telecom equipment. Its 50-position dual-row layout accommodates data buses, power rails, and mixed signal lines in a single compact 1.375-inch connector body.
