Miniature AC-LVDTs


LA-9.5 series of miniature AC-LVDTs (Linear Variable Differential Transformers) are small diameter contactless devices designed for industrial and commercial OEM applications in the factory automation, industrial, and test and measurement markets. The LA-9.5 AC-LVDTs feature infinite resolution, excellent linearity, and a wide operating temperature range, making them ideal for a wide variety of OEM position sensing applications where small size is important.


LA-9.5 series miniature AC-LVDTs operate from a nominal 3 Vrms, 2.5 - 3.3 kHz excitation source. They are packaged in a 0.375 in. (9.5 mm) OD SS housing with 12-inch leads and are offered with either an imperial or metric threaded 0.110 in. (2.8 mm) diameter core that works in a 0.125 in. (3.2 mm) ID bore. When mated with ASG’s SC-200 DIN-rail-mountable industrial AC-LVDT signal conditioner, an LA-9.5 series LVDT becomes part of a complete position measurement solution, especially where installation space is at a premium. ASG’s AC-LVDTs are also available in larger body and longer range versions, including the LA-19, LHA-19-A, LHA-19-R, LA-20.6, LA-21, LA-25, and LA-27 series.
