Image of Alliance Sensors LR-19 Series Position SensorThe Alliance Sensors Group LR-19 series linear variable inductance transducer (LVIT) position sensors 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 an excellent stroke-to-length ratio, the LR-19 sensors are ideal for industrial testing, laboratories, and OEM applications.

LR-19 sensors are offered in six full-scale ranges from 25 mm to 200 mm (1" to 8"). Operating from a variety of DC voltages, these sensors offer a choice of four analog outputs and all include the ASG 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.

Features
  • Proprietary SenSet field-adjustable range scaling
  • 10-32 or M5 x 0.8 male or female thread on end of axial operating rod
  • Axial termination version with either M-12 connector or 1 m cable
  • Excellent stroke-to-length ratio
  • LVIT Technology™
  • Contactless operation prevents wearout from dither or cycling
