J TEACHING FUNCTIONS
Four teaching methods are available to simplify setup and to allow changes in settings on the fly. The E3X-DA-N offers a new feature,
“pinpoint teaching” for positioning
Teaching function
Application Description
Maximum sensitivity setting Use this function for sensing objects without backgrounds or through–
beam sensing. It is ideal for detecting large objects.
Two-point teaching with or without
object
Minute level differences as thin as a piece of paper can be detected.
Detection of semi-transparent objects or the discrimination of object color
is also possible.
One-point teaching without object Set the sensitivity without stopping objects. This function allows automat-
ic detection of differences between objects and the background. Use it to
detect small moving items or thin objects such as gold wire.
Pinpoint teaching for positioning Allows high precision positioning when detecting electronic components
and other small items.
