Card Edge Connectors

6409 Series

The 6409 Series are connectors for DDR3 and DDR2 S.O. DIMM cards, which are compliant to JEDEC MO-268 and MO-224 standards. These products are 0.6mm pitch, SMT and vertical type connectors available with 204 positions (1.5V for DDR3) or 200 positions (1.8V for DDR2). Memory card boards can be securely fixed in the connectors due to arms on both ends which are raised by levers and fix the card boards when inserted. Suitable for various applications such as multifunction peripherals, printers, scanners, POS system terminals, etc.

  • Compliant to JEDEC MO-268 (DDR3) and MO-224 (DDR2) standards.
  • Saves space with vertical type connection, thus enabling other components to be mounted on adjacent areas.
  • The memory card board is securely fixed with guides on the levers of both sides, as well as a guide on the insulator housing for positioning in the pitch direction. When the card boards are inserted, levers raise arms on both ends which fix the card boards. They can be ejected easily by depressing the levers.
  • Contact pressure is improved by 50% compared with existing connectors, which contributes to the prevention of foreign matters.
  • Packaging options of with / without vacuuming tape and open / closed levers are available.
  • Contact Material: Copper alloy
  • Insulator Material: Heat-resistant plastic
  • Operating Temperature Range: -55 to +85°C
