microSD™Card Connectors
DM3 Series
■Features
◆Common to the entire Series 1. Extremely small size
Small external dimensions and the above-the-board height make the connectors the smallest on the market.
2. Rever card inrtion protection
Unique card slot design (patent pending) protects the connector from damage when the card is attempted to be inrted in rever, allowing it to re-inrted correctly.
3. Effective ground and shield configuration
4-connection points of the metal cover to the printed circuit board assures cure connection of the ground circuit and provides EMI protection.
4. Rigid and strong construction
Despite its small size, high-strengths materials ud in the connectors produced a strong and rigid structure.
5. Card detection switch
The card detection switch is Normally Open
6. RoHS compliant
All components and materials comply with the requirements of the EU Directive 2002/95/EC
◆DM3AT and DM3B (Push - Push, with ejection mechanism)
·Card fall-out prevention
Built-in card tray and the unique push inrtion-push ejection mechanism (patent pending) prevent accidental card ejection or fall-out.
Despite its small size the connectors will eject the card to a distance of 4.0 mm, allowing easy hold and removal of the card.
·Expod termination leads
Easy inspection and rework of the solder termination joints.
◆DM3C (Hinge, Push-Pull, manual, without ejection mechanism)
·Simple and reliable card inrtion
H inged metal cover provides location and guides the card during the inrtion / removal. Closing of the cover confirms the electrical and mechanical connection with a tactile click nsation.
·Reliable contact with the card contact pads
Unique contact design and card slide action will clean the contact areas of the card.
·Accessible termination areas
Contact solder terminations may be inspected and reworked.
◆DM3D (Push -Pull, manual, without ejection mechanism)
·Partial card inrtion hold
Card will not fall-out even when it is not fully inrted. Full inrtion and electrical / mechanical connection is confirmed with a distinct tactile feel.
·Accessible termination areas
An inner lead system that can be reworked is ud in this design.Contact solder terminations may be
inspected and reworked. ■Applications
Mobile phone terminals, digital cameras, PDA's, miniature
information terminals and any other portable device
