MD CONNECTOR Miniature circular connectors Standards ---------------------- 0 Recognized E60389 1 Certified LR20812 Shielding effect Shielding effect(dB) The extremely compact MD miniature circular connector has an outside diameter roughly half that of conventional circular DIN connectors. The connector's contact exclusively designed by JST dramatically reduces assembly time while improving contact reliability. The MD connector's shielding is superb. All you need to do is crimp the connector ground clip over the cable's braided shielding wire. Simple and reliable, JST's MD connector is well suited for the production of high-density office automation equipments as well as audio and video products. 10 20 30 40 50 60 70 80 90 100 110 30 Braided wires soldered to the metal shell MD connector(with ground clip) 100 300 600 Frequency(MHz) * Crimp contact with integral construction for improved reliability * Easy assembly without using special tools * Simple braid-to-connector assembly and effective EMI protection *The shielding effect differs depending on the wire specifications. * Refer to "General Instruction and Notice when using Terminals and Connectors" at the end of this catalog. * Contact JST for details. * Compliant with RoHS PC board layout Layout PC board layout (viewed from component side) Mating section layout 2.20.1 1 3 3 2.40.1 1 2.20.1 2 Note 13.50.1 2.50.05 8.5 max. 2.20.1 13.50.1 Hole dimensions (from the front) 6 5 1 3 2.60.05 Socket mating side surface Socket mating side surface 0.9 0.1 0 6.80.1 2 2.50.05 2 1.30.05 4 0.80.1 3 4 3.80.05 6 2 5 0.05 4 6 5 0.80.1 6 2.50.05 0.9 0.1 0 6.80.1 2.60.05 30.05 Socket mating side surface 13.50.1 1 3 0.80.1 1 Note 4 2.5 2.40.1 5 2.20.1 13.50.1 Hole dimensions (from the front) 8.5 max. 2 2 0.9 0.1 0 6.80.1 8.5 max. 3 1 Socket mating side surface 13.50.1 Hole dimensions (from the front) 30.05 5 3 4 3.80.05 5 4 0.80.1 5 2.50.05 0.9 0.1 0 2.20.1 30.05 Socket mating side surface 13.50.1 1.30.05 1 8.5 max.

Housing B must have the same number of orifices as there will be contacts in the connector. However, housing A can have a greater number of cavities (but never less). Thus in applications in which a user may require MD connectors with different pin counts, only one kind of "A" housing needs to be inventoried - the one with the highest pin count.

Housing Holder * Compact, high-density design This socket has a low profile with a mounting height of just 12.8 mm and width of 14 mm. It takes up little space on the printed circuit board, allowing high-density product design. * Spring locks make it easy to temporarily secure sockets to printed circuit boards for soldering The shielding tubes are equipped with spring locks which can be used to temporarily secure the sockets to printed circuit boards. This prevents the sockets from moving and ensures reliable soldering. Shielding tube A spring lock temporarily secures the socket to the printed circuit board. * Split round contact provides maximum contact area and contact redundancy The socket contact is split to insure redundant connection and is cylindrically shaped to provide maximum contact mating area. The result is a highly reliable connection to the mating pin. This superb contact performance is maintained even after many mating and unmating cycles. Standard type without shielding cover (left) Standard type with shielding cover (center) Type B (applicable to Type B plug) (right) (Front shielding type) * Front shielding construction A metal shielding cover integrating the connection part which connects to the plug's shell is used. Because there is no gap between the socket and the plug, this construction prevents the entry of space conductive noise. * Effective shielding * Flange construction With the front shielding construction and the flange construction, the shielding effect is improved by about 15 dB over the conventional models. The flange construction allows the socket to be secured on the equipment chassis with screws, ensuring more reliable electrical connection.
