LR-27 Series
LVIT Linear Position Sensor
Long Lasting, Contactless, Inductive Automation Sensors

Alliance Sensor Group's LR-27 series LVIT (Linear Variable Inductance Transducer) are contactless position sensors designed for factory automation systems and a variety of industrial and commercial applications, such as: solar cell positioners, wind turbine prop pitch and brakes, chute or gate positioners, on/off-road or agri-vehicles, and packaging machinery. The modular design, high-end performance, and excellent stroke-to-length ratio make the LR-27 sensors an ideal choice for in-plant or mobile equipment OEMs.


LR-27 series sensors are currently offered in 5 full scale ranges from 25 mm to 150 mm (1 to 6 inches). Operated from a variety of DC voltages.  These sensors offer a choice of four analog outputs and include ASG's proprietary SenSet™; field recalibration feature. LR-27 products are available with either a radial exiting cable and two spherical rod eye ends or with an axial cable or connector terminations.


The LR series also include a smaller body version, the LR-19, for applications not requiring a heavy-duty unit. 

For more information please see the technical datasheet below.
