Alliance Sensor Group's LRL-27 series LVIT (Linear Variable Inductance Transducer) contactless position sensors complement the LR series with extended ranges up to 18 inches (450 mm) in a compact package. These sensors are designed for use in factory automation systems and a wide variety of industrial and commercial applications. Cost effective with high-end performance and excellent stroke-to-length ratios make these sensors ideal choices for many industrial application.
LRL-27 sensors are offered in 6 nominal ranges from 8 to 18 inches (200 to 450 mm). Operated from a variety of DC voltages, these sensors offer the end-user a choice of four analog outputs along with ASG's proprietary SenSet™ field adjustable range scaling feature. LRL-27 sensors 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 has a smaller body version, the LR-19, for applications where a reduced body envelope is required or the LR-27 for shorter stroke lengths from 25 to 150 mm.
