This document is about Aries' Universal Test Socket product introduction, which features the ability to accept devices with a center distance of .300 to .600. All pin count sockets can be used on PCBs with either a .300 or .600 center distance.
The Aries X57X series is a universal test socket that accepts devices with 0.300 to 0.600 inch (7.62‑15.24 mm) center spacing. It features a swing quick‑release handle, optional left or right mounting, and can be soldered into PCBs or plugged into any socket.
Technical specifications include a stainless‑steel handle, brass‑alloy knob, multiple contact materials (Beryllium Copper, Spinodal, Beryllium Nickel), 1 A contact current rating, 1000 MΩ insulation resistance, 1000 VAC dielectric rating, and a life cycle of 25‑50 k cycles. The socket operates from –67 °F up to 482 °F depending on plating, and is available in 24‑48 pin configurations with standard and high‑temp body materials.
