Frequently Asked Questions
How many pins and what contact finish does the SDL-120-G-12 low-profile connector provide?
The SDL-120-G-12 delivers 120 pins with premium gold-plated beryllium copper contacts featuring 30 µm gold over 50 µm nickel finish. This contact plating ensures excellent durability, low contact resistance, and long service life in harsh industrial environments and high-cycle mating applications.
Is the SDL-120-G-12 suitable for high-density PCB layouts with low-profile space constraints?
Yes, the SDL-120-G-12 is specifically designed with a low-profile housing to fit space-constrained layouts while supporting 120 pins. The compact form factor combined with beryllium copper contacts makes it ideal for densely packed backplane systems and modular instrumentation where height clearance is limited.
What contact material and finish does the SDL-120-G-12 use to ensure long-term field reliability?
The SDL-120-G-12 uses beryllium copper contacts with gold over nickel plating (30 µm Au/50 µm Ni), providing superior corrosion resistance and low contact resistance across thousands of mating cycles. This premium combination ensures reliable signal integrity in harsh industrial and telecommunications applications operating in diverse environmental conditions.
