Figure 39 - Minimum Distance A from Reflective Surfaces (D= Distance between Receiver and
Transmitter)
The effective aperture angle for the 450L safety light curtain system is ±2.5° at a
mounting distance of ≥3.0 m (9.8 ft). Calculate the minimum distance to
reflective surfaces depending on the distance between the transmitter and the
receiver, with an aperture angle of 2.5°.
Mirrors
The GuardShield safety light curtains can be used with corner mirrors (see
). Mirrors are only allowed for applications without
undetected access into the protected area.

IMPORTANT
Formula: A [mm] = tan 2.5° x D = 43.7 × D [m]
A = Minimum distance to reflective surfaces
D = Distance between transmitter and receiver or take the appropriate
value from
