miniSDTM Card Connectors

DM2 Series

■Features

1. Extremely small size

Board footprint as well as the length, width and height of the

connector has been reduced in order to minimize use of

valuable space in today’s miniature devices. With the miniSD™

card inserted the overall length is shortest in the industry.

2. Push-in / Push-out card ejection

Inserted card is securely held in place with an approximate

force of 4 N, assuring reliable connection and retention in

the connector, even when subjected to accidental shock.

When pushed again, the card will self-eject to distance of 4

mm, allowing safe removal from the connector.

3. Protection against card loss

Built-in card retention springs will keep the card inserted

when card may be accidentally partially pulled-out.

4. Protection against reverse card insertion

The ejection mechanism is designed not to lock when the card

is inserted in reverse, alerting the user to insert it correctly.

Reverse card insertion will not damage the contacts.

5. Effective grounding and shielding

The VSS contacts connect directly to the metal cover,

assuring superior ground connection (Patents pending.) In

addition, metal cover will connect with the PC board

surface at four points, providing highly effective grounding

and shielding of the connector.

6. Durable, load-resistant construction

While miniature in size and lightweight, the use of metal

cover assures it’s reliable and stable performance.

7. Two-point contact

Two-point contact offers high contact reliability.

8. Built-in card detection switch

The card detection switch is a normally closed, opening

when the card is inserted.

9. RoHS Compliant

All components and materials comply with the requirements

of EU Directive 2002/95/EC.

■Applications

Mobile phones, digital cameras, PDA’s and any other

portable device requiring use of miniSDTM memory card.
