Overview
The UN-188 series of ultra-small AC LVDTs provide high-quality position measurement in space-constrained locations. It features a 4.77 mm diameter housing, offers a variety of measurement ranges, and provides customization options. The ultra-small size brings all the advantages of LVDT measurement technology, such as infinite resolution, excellent repeatability and hysteresis, and operation over wide temperature and pressure ranges, for applications with tight space constraints.
