SD Memory Card Connectors

DM1 Series

■Features

1. Withstands higher force of card insertion

Metal cover extends over the back of the connector

allowing it to withstand force of up to 400 N (static load)

when dropped or accidentally hit.

2. No damage to the card when accidentally

pulled-out

The connectors will release the card when a moderate

pull-out force of about 4 N is applied. There will be no

damage to the lock components and all connector

functions will not be affected.

3. Accidental card fall-out prevention

Built-in lock feature holds the card securely in place.

4. Reliable Card Insertion and Withdrawal

Built-in Push-in / Push-out ejection mechanism assures

simple and reliable card insertion and withdrawal.

5. Designed to accept Secure Digital I/O card

(Built-in Ground Contact)

The connector allows use of various expansion modules,

including the Bluetooth communication modules.

■Applications

Notebook PC's, digital cameras, PDA's, audio/video

equipment and other devices utilizing SD I/O cards.
