MicroSD™ card connector of world's smallest class

We are pleased to announce the development for market introduction this February of a microSD™ card connector for microSD™ (TransFlash™) cards that are attracting the industry's attention for being an ultra small memory card. Specifics of this connector are outlined below.

Dimensions of 1.65 mm high when mounted, 12.9 mm deep and 11.4 mm wide, an industry's smallest class, are a result of one-piece molded contacts and housing and unique shield cover design. Such dimensions effectively bring out the advantage in size of the ultra small microSD™ and contribute to thinner and smaller equipment design, including for mobile phones. (a 78% reduction in volume from our previous miniSD™ card connector)

Card insertion/removal depends on a sliding (manual) system with a normal type insertion direction). Employed with the card sensing switch is a sensing system which senses a card in a backward direction, making the structure non-susceptible to card dimensions. And, a half-locking mechanism is provided to positively hold cards and prevent them from flying out. Its shield cover employs a mechanism that augments shielding performance and connector strength.

The development of this product, together with a push (locking)/push (ejecting) type which has been on the market, optimizes our product repertoire. For further optimization of our connector repertoire, we will add more connectors applicable to various types of small memory cards.
