Frequently Asked Questions
What contact material and finish does the SFM-111-02-L-D-A-K use to ensure reliable mating performance?
The SFM-111-02-L-D-A-K uses beryllium copper contacts with a gold (10 µin) over nickel (50 µin) mating finish and matte tin over nickel barrier termination. This 22-position socket strip contact material combination provides low contact resistance, high corrosion resistance, and supports thousands of reliable mating cycles in high-reliability applications.
How does the 0.050 inch pitch benefit high-density PCB designs compared to standard 0.100 inch pitch connectors?
The SFM-111-02-L-D-A-K operates at 0.050 inch (1.27 mm) pitch, half the standard 2.54 mm pitch, allowing 22 positions in approximately the same board space as an 11-position 0.100 inch connector. This dual-row surface mount design enables twice the signal density per unit length, ideal for compact mezzanine and board-to-board applications where PCB area is limited.
Which applications require the high-reliability polarized socket strip design of the SFM-111-02-L-D-A-K?
The SFM-111-02-L-D-A-K is suited for aerospace avionics, medical imaging equipment, and industrial control systems requiring secure, repeated mating at 0.050 inch pitch with gold contact reliability. The polarized body prevents incorrect insertion across 22 dual-row positions, and the surface mount beryllium copper contacts maintain stable electrical performance under thermal cycling and mechanical vibration conditions.
