Distance (b) transmitter-receiver
Calculation of the minimum distance (a) to reflective sur-
faces
b ≤ 3 m
a [mm] = 131
b > 3 m
a [mm] = tan(2.5°) × 1000 × b [m] = 43.66 × b [m]
7.1.5
Resolution and safety distance during fixed blanking
The calculation of the safety distance must always be based on the effective resolution. If the effective res-
olution deviates from the physical resolution, this must be documented near the protective device on the
supplied sign in a lasting, wipe-resistant manner.

WARNING
Faulty application of blanking functions may result in serious injury!

Note that the additional distances to the safety distance may require additional measures be
taken for preventing stepping behind.
