The LDI-127 Series LVIT (Linear Variable InductiveTransducer) position sensors from trodeks® arecontactless devices designed for factory automationand a variety of industrial and commercial applicationssuch as solar cell positioners, wind turbine prop pitchand brakes, chute or gate positions on off-road oragri-vehicles and packing equipment. The modulardesign, high end performance and excellent stroke-to-lengthratio make the LDI-127 sensors ideal for in-plantor mobile equipment OEMs.

With their compact device, superior performance, andexcellent stroke-to-length ratio, the LDI-127 sensorsare ideal for both industrial testing, laboratories, andOEM applications.

LDI-127 sensors are offered in 5 full scale ranges from25 to 200 mm (1 to 8"). Operating from a variety ofDC voltages, these sensors offer a choice of outputsand all include the Field Programmability calibrationfeature. LDI-127 products come with radial exitingcable and two swivel rod eye ends for easy installation.The LDI series also include a smaller body version,the LDI-119, for those applications not requiring aheavy-duty unit.
