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.
