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.
A metal cam provides strong, smooth action as it moves to a positive stop, com-
pressing the double-sided contacts, ensuring a gas-tight seal.
Test point openings provided to reach all pins.
