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

■ 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 posi-
tioned at an oblique angle to the sensor.
