Sensing field
The sensing field diagram of the diffuse or the convergent reflective type sensor represents the boundary within which the sensor will be operated by the reflected beam from the standard sensing object.
The curves are plotted as a series of operating points at which the sensor enters the beam received state when the standard sensing object approaches from the left or the right for different setting distances (with the sensitivity adjuster at maximum sensitivity).
The graph is useful to determine the mounting position of the sensor with respect to the sensing object and the span between adjacently mounted sensors. (Note)
