microSD™ Card Connectors

DM3 Series

■

Features

◆

Common to the entire Series

1. Extremely small in size

Small external dimensions and the above-the-board height

make the connectors the smallest on the market.

◆

DM3D (Push -Pull, manual, without

ejection mechanism)

· Partial card insertion hold

Card will not fall-out even when it is not fully inserted. Full

insertion and electrical / mechanical connection is confirmed

with a distinct tactile feel.

2. Reverse card insertion protection

Unique card slot design (patented) protects the connector

from damage when the card is attempted to be inserted in

reverse, allowing it to re-inserted correctly.

· Accessible termination areas

An inner lead system that can be reworked is used in this design.

Contact solder terminations may be inspected and reworked.

3. Effective ground and shield configuration

4-connection points of the metal cover to the printed circuit

board assures secure connection of the ground circuit and

provides EMI protection.

4. Rigid and strong construction

Despite its small size, high-strengths materials used in the

connectors produced a strong and rigid structure.

5. Card detection switch

The card detection switch is Normally Open

◆

DM3AT and DM3BT (Push - Push, with

ejection mechanism)

· Card fall-out prevention

Built-in card tray and the unique push insertion-push ejection

mechanism (patented) prevent accidental card ejection or fall-

out.

Despite its small size the connectors will eject the card to a

distance of 4.0mm, allowing easy hold and removal of the card.

Push-Push

DM3AT

2~4

· Exposed termination leads

Easy inspection and rework of the solder termination joints.

DM3BT

5~6

◆

DM3CS (Hinge, Push-Pull, manual, without

ejection mechanism)

· Simple and reliable card insertion

Hinged metal cover provides location and guides the card

during the insertion / removal. Closing of the cover confirms

the electrical and mechanical connection with a tactile click

sensation.

Hinge-manual

ejection

DM3CS

· 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.

Push-Pull
