40-Pin Breakaway for 0.100" Pitch Interconnects
Current and Contact Finish
Gold mating finish (3.90 µin / 0.099 µm) provides corrosion resistance for moderate mating cycle duty; the tin-plated solder tails (118.1 µin / 3.00 µm) wet reliably during wave or hand soldering. The brass square pins carry the current without the contact resistance creep typical of tin-on-tin interfaces in high-humidity environments.
Overall contact length of 0.465" (11.81 mm) and a mating pin length of 0.228" (5.80 mm) set the engagement depth for the mating receptacle.
