LIGHT UP YOUR INDUSTRIAL IoT DESIGN 8 IIoT CHALLENGES AND ROHM SOLUTIONS Perhaps the most important issue in obtaining results commensurate with the investment cost of IIoT is understanding how to utilize the collected information. To this end, as introduced in the beginning in our definition of IoT, information collected from sensors is transmitted through high-reliability networks using wireless communication modules and processed by servers (the cloud). As such it is necessary to configure systems towards the concept of driving applications. To meet the requirements of IoT, ROHM supplies a broad range of solutions utilizing a variety of sensors and wireless communication technologies for both IoT and IIoT, along with evaluation kits that facilitate verification; and for smart logistics and factories we offer products such as thermal printheads. ROHM THERMAL PRINTHEADS ARE BEING ADOPTED FOR IIoT Thermal printheads are not only used in manufacturing and logistics to print labels for products and packaging materials but are also employed to print date of manufacture (date codes) directly on the packaging materials themselves. Regarding printing performance, from the viewpoint of work efficiency, it has been required to print relatively large quantities at high speeds (even LEARN MORE KX134 & KX132 Tri-axis Digital Accelerometers Figure 6: ROHM's TH300x series (Source: ROHM) if a little dirty), but in recent years, in consideration of safety and security along with the trend towards IIoT, it is necessary to print complex labels such as 2D bar codes that not only contain the date code but also detailed information to improve traceability. However, with conventional thermal printheads it is often imperative to reduce print speed (work efficiency) to improve print quality (information quantity and resolution), making it difficult to achieve high efficiency printing of large quantities of information. ROHM's TH300x series of high-definition, high-speed thermal printheads, released in 2019, is capable of ultra- high-speed printing at 1m/s at a high resolution of 305dpi on environmentally friendly paper and other media (Figure 6). In addition to achieving both high print speeds and high print quality, these heads also feature 7 times the corrosion resistance (longer life) of standard products. What's more, their robust design enables use even in special environments, allowing them to be adopted in thermal printers for printing date codes in food packaging, logistics, and quality control applications. With a host of benefits such as increased productivity, greater precision, speed, and lower maintenance costs, the Internet-of-things will continue to revolutionize the industrial sector for many years to come. IIoT applications including smart tags, industrial robots, drones, and logistics require reliable electronic components for sustainable operation in various industrial environments. ROHM is an industry-leading manufacturer of high- reliability components for IIoT applications, including thermal printheads, sensors, and wireless communication modules. ROHM's solutions are engineered using advanced manufacturing processes and highest-grade eco-friendly materials for durable operation. They are available in a broad range of industry footprints and package sizes.
