6.3 Mode of operation
The PY74 edge sensor operates based on the
laser triangulation principle. By means of special
optics, a laser beam is enlarged into a line and
projected to the surface of the object to be
measured. Using the multi-lens system, the
reflected light from this laser line is projected onto
a matrix. A controller calculates from this matrix
image the precise position e.g. of the beginning or
end of an object (i.e. of an edge) along the laser
line. Thanks to the new technology, the position of
the edge is output irrespectively of the distance
between the sensor and the object to be
measured. The sync input enables
synchronization of measurement data with an
object movement.
