Frequently Asked Questions
How does the 0.050" pitch of SFM-124-L2-SM-D-A-K compare to 0.100" pitch connectors for board-to-board designs?
The 0.050" (1.27 mm) pitch of the SFM-124-L2-SM-D-A-K provides twice the contact density per unit length compared to 0.100" pitch alternatives. A 48-position dual-row strip at 0.050" pitch occupies roughly half the board length of an equivalent 0.100" connector, making it ideal for space-constrained mezzanine and module stacking designs.
What makes the Tiger Eye contact in SFM-124-L2-SM-D-A-K reliable for high-cycle applications?
The Tiger Eye contact design incorporates a wiping motion during mating that cleans the contact surfaces and ensures consistent engagement. Combined with gold plating, this mechanism maintains low contact resistance across many mating cycles, making the SFM-124-L2-SM-D-A-K well suited for automated test equipment and field-serviceable boards requiring frequent connector mating.
For a 48-channel embedded computing module, does SFM-124-L2-SM-D-A-K support standard SMT reflow soldering?
Yes, the SFM-124-L2-SM-D-A-K uses surface-mount solder tails compatible with standard SMT reflow soldering processes. The connector can be placed by automated pick-and-place machines and reflowed in a standard lead-free solder profile, integrating 48 positions into a PCB without requiring additional through-hole drilling operations.
In what industries and application types is the SFM-124-L2-SM-D-A-K most commonly deployed?
This 48-position 0.050" pitch socket strip is commonly used in embedded computing mezzanine cards, industrial programmable logic controller expansion modules, telecommunications line cards, and data acquisition daughterboards. Its compact dual-row SMT footprint and high-reliability Tiger Eye contacts satisfy both space and reliability requirements in these demanding electronic environments.
