Mitsubishi Electric has developed what is believed to be the world’s first compact metal corrosion sensor small enough to be mounted on printed circuit boards. Its simple structure, incorporating a thin metal film and resistors and measuring just 1.6mm x 0.8mm, enables the sensor to be mounted directly on printed circuit boards and easily deployable across a wide range of products containing these, such as industrial equipment; believed to be a world-first. The new sensor utilizes metal corrosion monitoring technology developed by Mitsubishi Electric that detects the degree of corrosion of metal components caused by corrosive gases such as sulfur compounds in the atmosphere.
Detection under conditions more closely matching the environment inside the equipment eliminates the need to install additional measuring instruments such as external sensors. The deployment of multiple sensors with different levels of corrosion resistance allows the degree of corrosion to be detected in stages, helping to prevent equipment failure.

Mitsubishi Electric plans to deploy the new technology across its own industrial equipment portfolio.
