Connectors are designed with small width and depth for
miniaturization and the foot print on the board has been
made smaller. (See (a) to the right)
(b)Suitable for automatic mounting
2. Supplied with ground terminals
The MI21 Series are furnished with ground terminals.
3. Card ejection mechanism
Two point ejection mechanism to assure even card
ejection.
4. Designed and packaged for board placement
with automatic equipment
Headers are designed with a pick up area to accommodate
the pick-and -place nozzles of automatic mounting
machines. (Patents pending)
Receptacles are designed to be mounted on top the board,
and automatic mounting is possibble on the specified
board.
5. Card ejection mechanism
Available in several termination and mouting styles, with
and without ejection mechanism, with and without stand-
offs.
6. Rich variations
A rich assortment of variations allows selection of a type to suit
the specific card and the equipment to which it will be installed.
(1)Suitable cards: Type I , type I/II .
(2)Eject button: None, right , left
(3)Standoff: 0 mm, 2.2 mm
(4)Board mounting type: Standard , reverse
