The 70AAJ-3-F0 is a surface-mount modular female contact connector designed for stackable, high-cycle applications. It features a 2.54 mm pitch and height with 3 precious metal contacts, offering a current rating of 3 A per contact and a voltage rating of 60 V. The contact area is finished with 30 µ" minimum gold over nickel underplating, and the insulator is glass-reinforced thermoplastic rated UL 94V-0. The connector demonstrates excellent durability with a minimum of 50,000 mechanical cycles and maintains contact resistance below 50 mO after cycling, with an operating temperature range of -55°C to 125°C. This design is ideal for pick-and-place assembly in applications requiring reliable, stackable interconnections such as modular electronics, telecommunications equipment, and industrial control systems.
