Aries 516 Zero Insertion Force Socket is a zero insertion force socket that has a choice of 24, 28 or 40 pin count devices that can be inserted without bending or otherwise damaging the legs, since no force is required to either insert or remove the component from the socket. Contacts are normally open and are closed by a unique cam action controlled by dual lever arms. The last 15° of movement of the cam provides a wiping action to the contacts on the legs of the device to remove any residue, ensuring a gas-tight seal. Tapered entry guides help guide the device legs into the mating position with the contacts.
The Series 516 Zero Insertion Force (ZIF) socket allows insertion and removal of devices without bending the legs. A unique cam action with dual lever arms closes the contacts, and the final cam travel provides a wiping action for a gas‑tight seal. Tapered entry guides help align the device legs.
The manual lists technical specifications such as pin material (beryllium copper), current rating (1 A), operating temperature limits for different platings, and recommended PCB hole sizes. Mounting considerations and optional plating options (tin, tin/lead, gold) are also detailed.
