Memory Card Connectors
For CFTM Card, 1.27mm Pitch JC26C/JC26C2 Memory Card Connector
Series
The CF (CompactFlash*) card has quickly become popular for use as an
I/O card with applications for LANs, FAX and modems, in addition to
providing extended memory for digital still cameras and other
compact portable devices. Use of compact flash connector cards has
also increased due to the promotion of common standards by the CFA.
JAE has developed a new "JC26C2 type" memory card connector
for
compact flash cards with an enhanced anti-reverse insertion
structure.
*CF : CompactFlash "CompactFlash" is the registered trademark of
SanDisk Corporation in the US.
Features of JAE’s Memory Card Connector - JC26C2 Series:
- Composed of board-mount SMT type pin connector enabling automatic
packaging and frame.
- The JC26C is a frame connector with a card retention mechanism. The
board side pin connector is the same for both the JC26C and JC26A.
- Small, low profile, 5.8 mm high on board (basic type, board face
mount type).
- A stand-off type (1.6 mm) is also available, 7.4 mm high on board.
Other parts can be installed under the eject frame. Board face mount
type and board back mount type (reverse type) available.
- The eject mechanism of the card operates by pushing on both sides,
reliably ejecting the card every time. The eject button can be on
the left or right. A type with a retractable eject button is
available, to avoid damage in certain applications.
