1／4

 Compact and slim design --- 1.3 mm height, 17.5 mm width, 21.4

mm depth

 2 nano SIM cards can be installed in one connector

 Card mating condition --- With card detection switch (normally-

closed type)

 Contact buckling prevention structure that prevents deformation of

the contacts even if an empty card adapter is inserted.

 Mechanical lock structure that holds tray in place in case device is

dropped

 Tray mis-insertion countermeasure to prevent insertion of tray

upside down

 Compatible with nano SIM Cards that are manually cut to size by

user

For mobile devices with communication capabilities such as feature

phones, smartphones, and mobile routers, a SIM card is required,

and recently mobile device which can hold two SIM cards are

increasing.

Furthermore, the cards being adopted are shifting from micro SIM

cards to smaller nano SIM (4FF) cards.

The SF78 Series is a push-eject tray type dual nano SIM card

connector which can install two nano SIM cards.

(SIM: Subscriber Identity Module)
