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. 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.
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.
◆ 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.
· Accessible termination areas
An inner lead system that can be reworked is used in this design.
Contact solder terminations may be inspected and reworked.
5. Card detection switch

◆ 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 4.0 mm, allowing easy hold and removal of the card.
· Exposed termination leads
Easy inspection and rework of the solder termination joints.
◆ DM3CS (Hinge, Push-Pull, manual, without
ejection mechanism)
