Nowadays, the design and development of smart phones has reached an era of similarity. However, one thing has not changed much, that is, the SIM card of the mobile phone. From the earliest big card gradually evolved to MicroSIM, and then to the NanoSIM card launched by Apple, in general, the SIM card is developing in a smaller and smaller direction, and the most direct benefit is that in a limited machine Provide more space for placing functional components within the design space.
A few years ago, with the advent of eSIM (virtual SIM card), people are speculating that the physical SIM card will disappear in the future. However, as of today, it can be seen that in the smart phone, people are still very accustomed to using the NanoSIM card. .
Recently, foreign media have reported that the evolution of SIM card has come to a new stage. ARM, the world's leading semiconductor chip maker, announced the latest iSIM technology. The data shows that the technology integrates SIM cards at the SoC level of the ARM architecture, making it a new link between mobile phones and operators.
According to the data released by ARM, iSIM technology currently introduces a design platform called Kigen, which includes the Kigen OS system (in compliance with the GSMA specification) and independent hardware blocks with secure encryption.
According to the introduction given by ARM, the above platform will first be applied to IoT IoT devices, and may be gradually promoted to smartphone products in the future. According to the introduction, through the promotion of iSIM technology, users can obtain logistics information from the sensors of the truck at any time, and can also manage the inventory products in the warehouse in real time and effectively.
ARM hopes that by 2035, there will be more than one trillion devices integrating iSIM technology. However, the current technology may be like the previous eSIM, and may not be recognized by most operators.
The JUK universal Screw Terminal Block series has the typical features which are decisive for practical applications:
l The universal foot allows the terminal blocks to be easily snapped onto the NS35 or NS32 DIN Rail with G shape.
l Closed screw guide holes ensure screwdriver operation perfect.
l For terminal block with different wire cross-sectional areas, complete accessories are available, such as end plates, partition plates, etc.
l Potential distribution achieved by fixed bridges in the terminal center or insertion bridges in the clamping space.
l Same shape and pitch Grounding Terminal Blocks as the JUK universal series.
l Adopt ZB marker strip system,achieve unified identification.
