Series X55X Universal Zero-Insertion-Force
DIP Test Socket
FEATURES
• Aries Universal Test Socket accepts devices on 0.300 to 0.600 [7.62 to 15.24] cen-
ters.
• All pin count sockets go into PCB with either 0.300 or 0.600 [7.62 to 15.24] centers.
• Contacts are normally closed to eliminate dependence on plastic to sustain contact.
• Socket handle can be configured with closed contacts (on) when in the UP or DOWN
position, and can be mounted on either the right or left side.
• Sockets can be soldered into PCBs or plugged into any socket. Socket fits into Aries’
or any competitive test socket receptacle.
