The 40-0518-10 is a 40-pin, single-row collet socket from the Series 518, designed for reliable through-hole mounting applications. It features gold plating on both the 4-finger beryllium copper collet contacts and the brass shell, providing superior conductivity and corrosion resistance. This socket supports a current rating of 3 amps per pin and accepts lead diameters from 0.015 to 0.025 inches. The gold plating allows for a wide operating temperature range of -55°C to 125°C, and the UL 94V-0 glass-filled nylon body ensures durability, making it suitable for demanding prototyping and production environments.
