NEW microsd Card Connectors DM Series Features Common to the entire Series. Extremely small size Small external dimensions and the above-the-board height make the connectors the smallest on the market.. Reverse card insertion protection Unique card slot design (patent pending) protects the connector from damage when the card is attempted to be inserted in reverse, allowing it to re-inserted correctly.. 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 6. RoHS compliant All components and materials comply with the requirements of the EU Directive 00/95/EC DMAT and DMB (Push - Push, with ejection mechanism) Card fall-out prevention Built-in card tray and the unique push insertion-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. Exposed termination leads Easy inspection and rework of the solder termination joints. DMC (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. 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. DMD (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. Applications Mobile phone terminals, digital cameras, PDA's, miniature information terminals and any other portable device requiring use of small size high reliability microsd memory card connectors. etc. Card insertion-ejection Push-Push Hinge-manual insertion/ ejection Push-Pull manual insertion/ ejection Series Image Page DMAT DMB DMC DMD ~4 5~7 8~0 ~ 008.

In individual applications the actual temperature may vary, depending on solder paste type, volume / thickness and board size / thickness. Consult your solder paste and equipment manufacturer for specific recommendations. Precautions. Do not immerse or clean the entire connector with cleaning solutions as this may affect proper operation of the ejection mechanism and electrical performance of the connector. Do not apply excessive force to the connector when handling or after installation on the PC board.. 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 in the un-mounted connector. 5. Mounting on the Flexible Printed Circuit (FPC) To assure correct performance it is recommended that a flat reinforcement plate 0. mm min. thick be used under the 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 on the connector performance.
