Series 516 Zero-Insertion-Force Socket FEATURES • A choice of 24-, 28-, or 40-pin count devices 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 helps guide the device legs into the mating position with the contacts.
