RoHS compliant

Narrow pitch connectors

(0.35mm pitch)

FEATURES

1. Small size (Terminal pitch: 0.35 mm,
width: 2.5 mm and Mated height: 0.8
mm)

When mated, the footprint is reduced by
approx. 10% from A4S series (60 pin
contacts), contributing to the functionality
enhancement and size reduction of end
equipment.

3. Low-profile connector with up to
120 pin contacts.

4. Soldering terminals at each corner
enhance mounting strength.

5. Simple lock structure provides
tactile feedback to ensure excellent
mating/unmating operation feel.

6. Gull-wing-shaped terminals to
facilitate visual inspections.
