– Minimum distance for a vertically assembled AOPD
S = minimum distance in mm
H1 = height of the lowest beam
H2 = height of the uppermost beam
H1
≤ 300 mm*
H2 ≥ 900 mm
* 400 mm can be used for 2 beams
when the risk assessment allows it.
a) S

= (K × T) + C
RT
C
RT
= 850 mm for devices with resolution d > 40 mm
K = 1600 mm/s for devices with resolution d > 40 mm

= (K × T) + C
RO
K and T according to a).
C
RO
= Intrusion distance when reaching over the AOPD towards the hazard zone prior to the actuation of the
AOPD. This value depends on the height of the hazard zone and the height of the uppermost beam,
see EN ISO 13855:2010.
Horizontally assembled AOPD
Orion3 cannot be used horizontally.
Angled assembled AOPD
See the latest version of EN ISO 13855.
Practical examples
Let's suppose we have an Orion3 Base light grid in a vertical position and with no risk of reaching over it.
S = K × (T1 + T2) + C
