OMRON Corporation, Kyoto City, will introduce on April 1 the new confocal fiber displacement sensor ZW-7000 Series. Incorporating the new white light confocal principle(*2) of measurement, the ZW-7000 Series is a non-contact-type displacement sensor that can continuously measure the height of objects with various materials and shapes with an accuracy of microns while moving the sensor head.
Recently, manufacturers of smartphones and other digital devices are under pressure to maintain high-standard quality control for inspecting parts made with an increasingly diversified mix of materials and shapes to meet the requirements for high performance and a thin body unit and yet they also need to supply products in a timely manner.
Given such circumstances, what manufacturers expect from the quality inspection process is to measure the height of a target object precisely and promptly. However, previously available sensors used to make errors while moving the sensor head around to continuously measure objects with curved, shiny and coarse surfaces. As a result, manufacturers had to halt measurement to re-tune the direction and angle of the sensor head to ensure accurate measurement, making it difficult to achieve precise measurement and short inspection time at the same time.
Incorporating the white light confocal principle, OMRON’s newly developed ZW-7000 Series comes with a single sensor head which moves around and precisely measures the height of objects varying in material and shape. The ZW-7000 Series achieves high-precision and high-speed quality inspection, contributing to improvement in the quality of products, reduction in inspection time, and also quick set-up of the process.
