LA-9.5 Series
Miniature AC-LVDT
Reduced Size, Ideal of OEM Applications

The LA-9.5 series miniature AC-LVDT (Linear Variable Differential Transformer) linear position sensors by H.G. Schaevitz LLC  dba Alliance Sensors Group are contactless devices designed for industrial and commercial applications, such as: factory automation, automotive test stands, solar cell positioners, robotic assembly systems, packaging equipment, and motorsports. Their compact size, superior performance, and excellent stroke-to-length ratio, make the LA-9.5 AC-LVDT sensors ideal for use in test and measurement laboratories, industrial automation equipment, and many OEM position sensing applications.

LA-9.5 series AC-LVDTs are offered in 7 ranges from ±0.025 to ±2.0 inches (±0.635 to ±50.8 mm) with excellent linearity and infinite resolution. LA-9.5 series AC-LVDTs operate from a nominal 3 Vrms, 2.5 to 3.3 kHz excitation source. They are packaged in a 0.375 inch (9.5 mm) OD stainless steel housing, come with either a unified or metric threaded 0.110 inch (2.8mm) diameter core, have a 0.125 inch (3.2mm) ID for a reasonable core-to-bore clearance, and feature 12 inch (300 mm) long lead wires.  When mated with ASG's industrial AC-LVDT DIN-rail-mountable signal conditioner, an LA-9.5 AC-LVDT becomes part of a complete measurement solution.


ASG's AC LVDTs are also offered in larger body and longer range versions, including the LA-19, LHA-19, LA-21, LA-25, and LA-27.
