2.1.1 Frame Width
The frame Width has to be calculated according to the distances shown in the following
figure:
STS Main Plate Dimensions
STS400-xx7 and -xx8 = 1065 mm
(41.9 in)
STS400-xx5 and -xx6 = 785 mm
(30.9 in)
STS Main Plate
Conveyor Width
Max Side Room
Safe Safe
Max Side Room
W
The Safe clearance between the frame and the conveyor sides has to be chosen according
to the Maximum Side Room available. It is suggested to always keep at least of 200 mm of
Safe clearance.
The length of the frame profiles W can be calculated in 2 ways, according to whether the
STS400™ main plate is wider than the conveyor Conveyor Width or not:
If Conveyor Width > STS Main Plate then:
W = Conveyor Width + (2 * Safe Margin)
If Conveyor Width STS Main Plate then:
W = STS Main Plate + (2 * Safe Margin)
Note: The STS400-xx7 models require a 70 or 55 mm shift to center the FOV over the
conveyor and therefore must be accounted for in the frame width calculation.
2.1.2 Frame Length
It is suggested to keep at least 500 mm of Safe clearance for the frame Length (L). This
allows good frame stability and freedom for moving both the reading phase sensor(s) and the
STS400™, forward or backward:

Note: There is not a specific calculation for (L).
