It carries 10 positions — 8 data lines plus 2 dedicated to the card detect switch — and terminates via right-angle SMT tails. The hinged lid retains the card positively without a spring-loaded ejection mechanism, which simplifies the insertion cycle and reduces the number of moving parts that can jam in the field. Gold contacts are standard across the DM3 series, giving reliable mating over the card's insertion life. The 1.83 mm height above board is the key dimension for enclosure fit — it's low enough for most handheld and portable designs, though the DM3D-SF sibling shaves that to 1.55 mm if every tenth of a millimetre matters. ## Hinged Lid vs Push-Pull — Which Insertion Method Fits Your Build The DM3CS-SF uses a hinged lid — you flip the cover open, drop the card in, and close it. The DM3D-SF and DM3D-SF(41) use a push-in, pull-out method, where the card inserts and a spring-loaded mechanism holds it. The hinged lid gives a more positive retention feel and eliminates the push-push mechanism that can wear or jam, but it requires clearance above the connector for the lid to swing open. The DM3D-SF sits at 1.55 mm above board versus the DM3CS-SF's 1.83 mm — a 0.28 mm difference that matters when the enclosure lid is tight against the top of the card. Both carry the same 10 (8+2) position count, gold contacts, and card detect switch. The choice comes down to whether you want a flip-cover or a push-push action, and whether the extra 0.28 mm of height is available.","metaTitle":"Hirose DM3CS-SF microSD Connector, 10-Pos, Hinged Lid","metaDescription":"Hirose DM3CS-SF microSD card connector, 10 (8+2) positions, right-angle SMT, hinged lid, gold contacts, 1.83mm height.
