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, a LA-9.5 series 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.
