Industrial IoT

The factory of the future will only become smarter, with industrial automation equipment increasing productivity and manufacturing output. Designing smart factory systems calls for sophisticated sensors, embedded processing, and robust security. 



Smart, ultra-small sensors are at the heart of automated factory equipment, collecting data about parameters such as proximity, temperature, and pressure that fuels intelligent decision-making. Sensors play a central role in optimizing assembly lines, preventing unscheduled maintenance, and aligning production with market needs.

All of the data gathered by smart sensors needs to be processed, often in real time, by compact programmable logic controllers (PLCs) that drive distributed control in factories. The demands of the industrial IoT (IIoT) are pushing for massive compute capability, lower power, and smaller size to enable increased manufacturing productivity.

Low-Power Microprocessors


IO-Link technology is enabling traditional binary or analog sensors to become intelligent sensors. The settings for intelligent sensors can be changed remotely and on-the-fly based on real-time feedback on the health and status of other sensors on the factory line as well as the manufacturing operation it needs to perform. IO-Link technology can help unleash the power of Industry 4.0 and IIoT for greater manufacturing efficiency. From a design standpoint, Industry 4.0 and IIoT are shrinking automation equipment, driving the need for lower power consumption and less heat dissipation. PLCs need to provide greater functionality in smaller enclosures, so such systems must be more power efficient to prevent the PLC from overheating. Maxim’s Pocket IO technology shows how analog integration can lower heat dissipation while providing faster throughput in a small footprint.

Securing the IIoT requires safeguarding all of the key technology areas that touch the data being collected and analyzed, from the sensors to the network to the software and servers. Secure control modules can detect counterfeit products and ensure that the correct modules are being used within a system, as well as ensure that the data itself is unaltered.
