LVIT Linear Position Sensor
Long Lasting, Contactless, Inductive Sensors

The LR-19 series LVIT (Linear Variable Inductance Transducer) position sensors by Alliance Sensors Group are contactless devices designed for factory automation and a variety of industrial and commercial applications, such as: motorsport vehicles, automotive testing, solar cell positioners, wind turbine prop pitch and brake position, and packaging equipment. A compact design with superior performance, and excellent stroke-to-length ratio, the LR-19 sensors are ideal for industrial testing, laboratories and OEM applications.


LR-19 sensors are offered in 6 full scale ranges from (1 to 8 inches) 25 to 200 mm. Operating from a variety of DC voltages, these sensors offer a choice of four analog outputs and all include ASG’s proprietary SenSet™ field recalibration feature. LR-19 products are available with axial cable or connector terminations, or with radial exiting cable or two swivel rod eye ends for easy installation.


The LR series also includes a larger body version, the LR-27 for applications which require a heavy-duty unit.

For more information see the technical datasheets below.
