2 Types of nano SIM card Connectors
Achieving Industry's Lowest-in-class Height and Smallest-in-class Dimensions
Push-eject Tray Type "SF70 Series" and Push-push Type "SF72 Series" Has Been Developed


SF70 series and SF72 series

As information communication devices such as smartphones continue to get increasingly multi-functional, they are also getting slimmer and smaller in size. Consequently, the demands for nano SIM cards (4FF SIM ) which are smaller than micro SIM (3FF SIM) are increasing more than before.

To meet these demands, JAE has developed the SF70 Series and the SF72 Series nano SIM card connectors with the industry’s lowest-in-class height and smallest-in-class dimensions.

The SF70 Series is a tray type connector with a push-eject structure that enables insertion of the SIM card by placing the card on a tray and inserting the whole tray.
Along with the slimming of devices, SIM card connectors are now more often installed on the rear side of the smartphone, and the tray can be produced by the customers to fit the design of the smartphone.
Also, it achieves a high level of drop impact resistance with an original tray lock structure that holds the SIM card in place without falling out when the phone falls down.

The SF72 Series is a push-push type connector suitable for use when the SIM card is installed inside of the device and it features a good operability with a design that has an enlarged card eject length.

Both the SF70 and the SF72 Series achieve the industry's lowest-in-class height 1.25mm and the smallest-in-class dimensions 196.8mm2 (SF70 Series) and 160.7mm2 (SF72 Series), and can be selected according to the needs of the customers.
