“” construction
for high contact reliability.
3. Soldering terminals at each corner
enhance mounting strength.
4. Simple lock structure provides
tactile feedback to ensure excellent
mating/unmating operation feel.
5. Gull-wing-shaped terminals to
facilitate visual inspections.
APPLICATIONS
Ideal for board-to-FPC connections in
mobile equipment that requires size
and thickness reduction and
functionality enhancement.
