Realization of CBM using vibration pickup sensor VP8021-A CBM has been one of the biggest challenges facing many companies in recent years. This is especially true in the industrial machinery industry, where replacement is difficult because of the large opportunity loss in the event of failure and the high unit price. This time, we introduce IMV's vibration pickup sensor VP8021-A, which plays an important role in realizing CBM.

High-Precision distance measurement system with Symeo millimeter wave radar In the steel industry, slabs, coils in large - scale indoor and outdoor facilities due to the nature of heavy objects, such as slabs, coils, steel plates, and containers handled at container terminals. Naturally, heavy products are usually transported by large cranes. When transporting products that are placed in complex facilities or locations, high crane operation technology and safety are required, and efficient handling and heavy object management and safety must be ensured by an automated system using a range measurement system. It is also required to have environmental resistance because it is installed in severe environments such as large amounts of dust such as steam and smoke, and extreme temperature changes. To meet these requirements, Analog Devices Symeo has developed and provides customers with sensor systems that integrate hardware and software that are robust, maintenance - free, and easy to install, such as range measurement, location detection, and collision avoidance.

ADI 5G millimeter-wave radar development platform Analog Devices' mixed signal front end AD9081/AD9082 and synthesizer ADF4371 accelerate the development of your broadband networking applications. Giga Farm, an alliance partner of Analog Devices, 5G millimeter-wave radar development platforms, including FMC boards and clock generators using these products. This article provides an easy-to-understand explanation of the platforms and devices that accelerate the development of 5G, millimeter-wave and radar.

What are Analog Devices products with functional safety Functional safety is one of the ways to ensure an acceptable level of safety by introducing functions that ensure safety. IEC 61508 establishes standards for the design of industrial equipment based on functional safety. Based on IEC 61508, ISO 26262 for automobiles and IEC 61131-6 for programmable controllers IEC - 6 for programmable controllers. Other functional safety standards, such as ISO 13849 and DO178B/DO254, are not derived from IEC 61508.

Record system error caused by power supply circuit It is common to incorporate a mechanism in the circuit that monitors the power supply circuit and raises an alert when there is a system abnormality or power supply abnormality. It's good to monitor the power circuit, but it's very hard to see what kind of problem occurred on which power supply. In such cases, it is very useful to be able to record the log when an error occurs. Now let's talk about logging solutions.

Electronic circuit breaker with current detection amplifier If the power supply is short-circuited due to a circuit failure or operation error, an overcurrent flows, which leads to a secondary failure of the power supply. In addition, heat generated from the circuit components can cause an accident such as a fire. For this reason, many power supplies have a protective function such as a current limiting function, but I think there are many cases where a fuse is inserted to improve reliability. However, the fuse may be blown by the rush current when the power is turned on if the error of the blowing current is large and there is no margin. Also, once it has melted, it needs to be replaced, which makes maintenance troublesome.

Electronic circuit breaker with input overvoltage protection In the case of the power supply of the receiving electronics connected to the power supply terminal, in addition to the protection by current limitation due to the failure of the load circuit, protection of overvoltage due to ringing and surge generated when the cable is connected may be required. This can be easily accomplished using LT4363.

Self-resetting electronic circuit breaker In related article "Electronic circuit breaker with current detection amplifier" I introduced that breaker can be reset by turning on the power again or resetting by the LE terminal (temporarily set to low) after removing the fault. However, in the case of the master unit which supplies power to multiple slave units remotely, it may be difficult to set the reset terminal for each slave unit port or it may be convenient to automatically reset. In such cases, it is useful to retry periodically and return automatically. This can be achieved with the additional circuit in LT6118, but it can be more easily achieved with LT1910.

Low latency, low power consumption, high EMC industrial PHY ADIN1200/ADIN1300 Industrial ethernet must be more robust than standard office ethernet to ensure that certain data can be transmitted and received accurately, even in harsh industrial environments such as high temperatures, vibration, noise, and noise. Analog Devices' industrial Ethernet PHY ADIN1200 and ADIN1300 provide more accurate and reliable industrial Ethernet communications.

Low delay 50mbps communication! Analog Devices' new serial bus A2B A2B is an abbreviation for "Automotive Audio Bus". As the name suggests, it is a new technology developed with the aim of reducing the weight (fuel efficiency) and cost of audio harnesses used in in - vehicle infotainment systems, which are becoming increasingly popular. In addition to Ford Motor Co. of the United States, several other manufacturers in Japan, the United States, and Europe are planning to this bus in mass - produced vehicles, and it is expected to become a standard communication bus for the car audio industry in the near future.
