Height of the protected area
Here it is important to distinguish between the "Height of the
sensing area" and the "Height of the protected area" (Fig. 3).
- The height of the sensing area is the distance between the
upper limit of the first lens and the lower limit of the last lens.
- The height of the protected area is the effective protected area,
in which an opaque object whose size is greater than or equal to
the resolution of the light curtain will safely obscure the beam.

Safety distance
Great care must be taken when calculating the distance at which
the safety device should be positioned in relation to the hazardous
machinery. (Please see Ch. 2, "Installation", for details of how to
calculate the safety distance.)
