The product informationthis catalog is for reference only. Please request the EngineeringDrawing for the most current and accurate design information.NEWmicroSD Card ConnectorsDM3 Series■Features◆ Common to the entire Series1. Extremely small sizeSmall external dimensions and the above-the-board heightmake the connectors the smallest on the market.2. Reverse card insertion protectionUnique card slot design (patented) protects the connectorfrom damage when the card is attempted to be inserted inreverse, allowing it to re-inserted correctly.3. Effective ground and shield configuration4-connection points of the metal cover to the printed circuitboard assures secure connection of the ground circuit andprovides EMI protection.4. Rigid and strong constructionDespite its small size, high-strengths materials used in theconnectors produced a strong and rigid structure.5. Card detection switchThe card detection switch is Normally Open◆ DM3D (Push -Pull, manual, withoutejection mechanism)· Partial card insertion holdCard will not fall-out even when it is not fully inserted. Fullinsertion and electrical / mechanical connection is confirmedwith a distinct tactile feel.· Accessible termination areasAn inner lead system that can be reworked is used in this design.Contact solder terminations may be inspected and reworked.Card insertion-ejectionSeries Image Page◆ DM3AT and DM3BT (Push - Push, withejection mechanism)· Card fall-out preventionBuilt-in card tray and the unique push insertion-push ejectionmechanism (patented) prevent accidental card ejection or fallout.Despite its small size the connectors will eject the card to adistance of 4.0 mm, allowing easy hold and removal of the card.· Exposed termination leadsEasy inspection and rework of the solder termination joints.◆ DM3CS (Hinge, Push-Pull, manual, withoutejection mechanism)· Simple and reliable card insertionHinged metal cover provides location and guides the cardduring the insertion / removal. Closing of the cover confirmsthe electrical and mechanical connection with a tactile clicksensation.· Reliable contact with the card contact padsUnique contact design and card slide action will clean thecontact areas of the card.· Accessible termination areasContact solder terminations may be inspected and reworked.Push-PushHinge-manualinsertion/ejectionPush-Pullmanual insertion/ejectionDM3ATDM3BTDM3CSDM3D2~45~67~89~102010.6w1

Consult your solder paste and equipmentmanufacturer for specific recommendations.■Precautions1. Do not immerse or clean the entire connector with cleaning solutions as this may affect proper operation of theejection mechanism and electrical performance of the connector2. Do not apply excessive force to the connector when handling or after installation on the PC board.3. The connectors will reliably connect and operate with the correctly inserted microSD TM cards.Follow the correct insertion / ejection procedure for the specific connector in use.Attempts of incorrect insertion of the card may cause damage to the connector or the card.4. The connector must be correctly mounted on the PC board before the card can be inserted. Do not insert the card inthe un-mounted connector.5. Mounting on the Flexible Printed Circuit (FPC)To assure correct performance it is recommended that a flat reinforcement plate 0.3 mm min. thick be used underthe FPC.6. Small visible residual manufacturing fluids or tooling marks do not affect connector's performance.7. Repeated insertions and removal of the cards may leave some marks on the card itself. This will have no affect onthe connector performance.● Refer to applicable Operation Manual listed below for additional precautions.SeriesDM3AT SeriesDM3BT SeriesDM3CS SeriesDM3D SeriesOperation Manual NumberETAD-F0345ETAD-F0324ETAD-F0335ETAD-F035311
