Hermetically Sealed AC-LVDTs Integrate Radial Connector

Alliance Sensors Group, expands its linear position sensor line with the LAS-19-R series spring-loaded Linear Variable Differential Transformers (AC-LVDTs). The linear sensing devices are spring loaded, hermetically sealed, contactless devices with a radial connector designed for industrial and commercial applications such as factory automation, metal and paper mills, valve stem position, robotic assembly systems, pharmaceutical and food manufacturing, and operation in wet environments.


The components specify a wide operating temperature range, making them viable for use in power generation facilities and industrial automation equipment. Features include:
