Compared with the ordinary hinge type socket design which card is placed on the base chamber and press down the cover to lock it in the market, ATTENDs design changes the card placement from base chamber to the cover.
The design concept is considered the size of a Nano sim card is too small to place it on the right spot. It is easier for the operator to slide it into the cover and secure it tightly. This design makes it can pass Random vibration and 50G Mechanical Shock test under the EN/IEC 60721 part 3-5, class 5M3 Dedicated standard for Vehicle Market. Moreover, wider operating temperature from -40? to +105? is suitable for embedded systems or automotive devices.
Industrial M2M Sim Cards are optimized to:
Rigorous environment
Giving more versatility and longevity than normal for devices and users
Temperatures -40C~105C instead of 25C~85C standard SIMs
Endure a long life span
Survive extremes of vibration, temperature, and humidity common to M2M applications
Occupy a small footprint (miniaturization)
Withstand and integrate into industrial manufacturing processes
