■Features

1. Reduced size and board-occupied area

With the mated height of 0.98/1.5mm, width of

2.98mm and length of 8.22mm (30 positions) the

connectors are one of the smallest in its class. Also

2.6mm depth short-lead type is available. (Fig.1)

Sufficiently large flat areas allow pick-up with

vacuum nozzles of automatic placement

equipment.

2. Reliable electrical and mechanical

connection

Despite its small mated height, unique contact

configuration, with a 2-point contacts and effective

mating length of 0.25mm, assures highly reliable

connection while confirming a complete mating with

a definite tactile feel.

3. Self alignment

Recognizing the difficulties of mating extremely small

connectors in limited spaces, the connectors will self-

align within 0.3mm.

4. Physical shock and vibration protection

2-point contact assures electrical connection in a

shock or vibration applications. (Fig.2)

Contact areas are not exposed to the outside

penetration of the flux or other physical particles.

5. Solder wicking prevention

Nickel barriers (receptacles) and unique forming of the

contacts (headers) prevent un-intentional solder

wicking.

Contact areas

6. Contamination protection

Insulator walls protect the contact areas against flux

splatter or other physical particles contamination. (Fig.3)

In cases where the application will demand a high level of reliability, such as automotive,

please contact a company representative for further information.
