Mounting Space Saving
microSDTM Small Memory Card and
GSM 11.11 Plug in SIM Card Combo Connector
ST7 Series Has Been Developed

ST7 series connector

 

 

 

 
 Recently, the number of mobile phones with small memory cards is increasing due to the popularity of hybrid cell phones with audio players, one-segment TV and GPS functions. With the spread of 3rd - 3.9th generation phones, phones equipped with a GSM 11.11 Standard Plug-in SIM Card are now common.
For this reason, JAE has developed a new combo connector compatible with both the GSM 11.11 Plug in SIM Card and the microSDTM Card, which has a high share in the small memory market, in order to expand the variety of card connectors available.
The ST7 Series will significantly save mounting space for customers compared with the conventional method of mounting the SIM Card and small memory card connectors separately, and will contribute to expanding the design variation of small devices.
