The LHA-19-R series AC-LVDT (Linear Variable Differential Transformer) linear position sensors by H.G. Schaevitz LLC dba Alliance Sensors Group are hermetically sealed, contactless devices with a radial connector, designed for industrial and commercial applications such as factory automation, metal and paper mills, valve position, robotic assembly systems, pharmaceutical and food manufacturing, and wet environment applications. These ruggedized linear devices have excellent price vs performance and stroke-to-length ratio, making LHA-19-R AC-LVDT sensors ideal for use in power generation and industrial automation equipment, and many OEM positioning applications.
LHA-19-R series AC-LVDTs are offered in 12 ranges from +/-.050 to 10.0 inches (+/-1.27 to 254.0 mm) with excellent linearity and infinite resolution. LHA-19-R series AC-LVDTs operate from a nominal 3 Vrms, 2.5- 3.3 kHz excitation source. They are packaged in a 0.750 inch (19.0 mm) OD SS housing and are offered with either an imperial or metric threaded 0.188 inch (4.8 mm) diameter core, a radial 6-pin PTO2A-10-6P connector, and have a 0.235 inch (6.0 mm) ID for good core-to-bore clearance. They feature a wide operating temperature range.
