c18 smartmedia connectors mcr102a series tm features 1. conforms to the ssfdc forum proposal of "smartmedia" miniature storage media product development using postage stamp sized miniature memory cards for such items as digital cameras and pda is now a regular practice. the mcr102 series of miniature, thin connectors conforms to the ssfdc forum proposal of "smartmedia" miniature storage media. 2. miniature low-profile smt board occupation area was taken into account in the design of these miniature,thin connectors, the dimensions of which are 40 mm wide, 38.5 mm long, and 3.0 mm high (excluding the card insertion slot). the covers are designed to make connection with the ground of the printed circuit board. 3. connectors are available in theree types:a 3.3-v card type, a 5-v card type, and a combined type for both 3.3-v and 5-v cards. 4. prevention of incorrect card insertion an incorrect insertion prevention mechanism serves to prevent the insertion of a different type of voltage card. the combined type can use 3.3-v and 5-v cards. 5. original card detection switch mechanism (patents pending) the contact portion separates when the card has been firmily inserted all the way.(normally closed type) the switch contact portion is of the two-point contact type which improves contact stability.the contact timing of the signal contacts and switch contacts is as follows. after the signal contacts makes contacts makes contact, there is a 1.2 mm distance until the switch contact operates and this permits reliable card detection. the 3.3 v/5 v combined card, witch is currently being standardized (with a provisional name of dual voltage card), is also designed with a structure that permits card detection. 6. equiped with write protect (wp) contact for erroneous data deletion protection 7. equiped with a board positioning boss. the boss position prevents incorrect insertion to the board. 8. suited to automatic mounting a placement area of 8.2 mm x 30 mm has been maintained to correspond with the placement nozzle of the automatic mounter. 9. solder repairability the smt arrangement of the 2 rows of 22 signal pins into a single row on one side improves the level of solder repairability. applications digital cameras, pda, voice recorders, and other equipment that uses smartmedia.
