LRS-18 Series
Spring-Loaded LVIT Linear Position Sensor
Long Lasting, Contactless, Inductive Sensors

The LRS-18 series of LVIT (Linear Variable Inductance Transducer) spring-loaded position sensors by Alliance Sensors Group are contactless devices designed for dimension or position measuring applications in factory automation and in various industrial and commercial applications, such as: automotive testing, mil/aero test stands, robotic arms, and packaging equipment. An ideal solution for when the sensing element cannot be attached to the object being measured. LRS-18s are offered in full scale ranges from 0.5 to 4.0 inches (12.5 to 100 mm) with excellent resolution and high stroke-to-length ratios. The maximum tip force on the item being measured is 1 pound.


LRS-18 sensors have a 0.75 inch (19 mm) diameter aluminum or stainless steel body with an M18 x 1 thread and come with two hex jam nuts for easy installation in place of an 18 mm analog prox sensor. These sensors use a 0.25 inch diameter probe equipped with an AGD No. 9 contact tip, and are offered with either an axial cable or a connector. Operating from a variety of DC voltages. These sensors are available with a choice of four analog outputs and they all include ASG’s proprietary SenSet™ field recalibration feature.

For more information see the technical datasheet below.
