Sensing Various Objects
Offset Error vs. Object Material
When detecting a variety of objects successively, refer to the offset
error graph below. The graph illustrates the change in sensor output
characteristics when black paper is compared to white paper. To re-
duce the offset error value, install the Sensor so that objects are de-
tected at or as close as possible to the measurement point.

fset Error (% FS)
Angle Characteristics
The angle characteristics were obtained by detecting an object with
different angles of inclination at the measurement point and plotting
the analog output error resulting from each operation.
The LED Displacement Sensor is designed to detect the front of an
object facing the sensor. Error occurs when the object is positioned
at an oblique angle to the sensor.
