MICRO PIN GRID ARRAY
SOCKETS
1.27 mm GRID / SOLDER TAIL / SURFACE MOUNT / INTERCONNECT PIN
Other plating on request (see page 178 for plating specs).
Replace NNN with the number of poles and XX-XXX with body size
and layout numbers as indicated on page 168.
For example a 26x26 pin configuration with window and 478 contacts
as shown on page 168 becomes 518-77-478M26-131105.
