SD Memory Card Connectors
DM1 Series
NEW
2003.4
s
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.
s
Applications
Notebook PC's, digital cameras, PDA's, audio/video
equipment and other devices utilizing SD I/O cards.
