LVDT Spring-Loaded Linear Position Sensor LAS-19-A
Spring-Loaded AC LVDT
Ideal for High Duty Industrial Applications

The LAS-19-A series AC-LVDT (Linear Variable Differential Transformer) linear position sensors by H.G. Schaevitz LLC dba Alliance Sensors Group are spring-loaded, hermetically-sealed, contactless devices designed for industrial and commercial applications such as factory automation, metal and paper mills, valve position, robotic assembly systems, pharmaceutical and food manufacturing, and outdoor applications. This ruggedized linear sensing device has excellent price-to-performance and stroke-to-length ratios, making the LAS-19-A sensors ideal for use in power generation and industrial automation equipment, and in many OEM positioning applications.

LAS-19-A series AC-LVDTs are offered in 6 ranges from ±0.050 to ±2.00 inches (±1.27 to ±50 mm) with excellent linearity and infinite resolution. LAS-19-A series AC-LVDTs operate from a nominal 3 Vrms, 2.5 to 3.3 kHz excitation source. They are packaged in a 0.750 inch (19.0 mm) OD hermetically-sealed stainless steel housing with a ½-20 UNF mounting thread and two hex jam nuts, a 0.210 inch diameter (5.3 mm) probe with an AGD No 9 contact tip, and a PTO2-10-6P (6-pin) axial connector.

When mated with ASG’s industrial AC-LVDT DIN-rail-mountable signal conditioner, an LAS-19-A series AC-LVDT becomes part of a complete measurement solution.

ASG AC-LVDTs are also offered in larger body and longer range versions, including the LA-9.5, LA-19, LA-20.6, LA-21, LA-25, and LA-27.
