Pepperl+Fuchs: Linear inductive sensors

With these new models, the company’s line of PMI linear inductive sensors are now available with linear ranges of 14mm, 40mm, 80mm, 104mm and 120mm to satisfy a wide range of sensing requirements.

Unlike cylindrical analog sensors, PMI sensors do not measure changes in distance so the vibration and machine tolerance of the vertical valve do not affect position and accuracy. As a result, the PMI sensor helps improve the overall accuracy of a machine’s processes.

The optimal distance from PMI40 to the standard sensor target (BT-F90-W) is 2mm, but an available sensing range of 0.5 to 3 mm delivers accurate linear position regardless of the sensing range. The 40 mm linear distance delivers 33 um resolution. The shorter housing of the PMI40 enables it to be applied where models with longer housings are unsuitable.
