[For use in Europe (EU) (as EN 999)] (For intrusion direction perpendicular to the sensing area)
Equation 1
S = K × T + C
S :
Safety
distance
(mm)
Minimum required distance between the sensing area surface and the dangerous
parts of the machine
K
: Intrusion velocity of operator’s body or object (mm/s)
Taken as 2,000 (mm/s) for calculation
T
: Response time of total equipment (s)
T = T
m
+ T
SF4
T
m
: Maximum halting time of device (s)
T
SF4
: Response time of this device (s)
C : Additional distance calculated from the size of the minimum sensing object of
the sensor (mm)
However, the value of C cannot be 0 or less.
C = 8 × (d - 14)
d: Minimum sensing object diameter (mm)

For calculating the safety distance S, there are the following five cases.
First calculate by substituting the value K = 2,000 (mm/s) in the equation above. Then, classify the
obtained value of S into three cases, 1) S < 100, 2) 100
≤
S
≤
500, and 3) S > 500.
For Case 3) S > 500, recalculate by substituting the value K = 1,600 (mm/s). After that, classify the
calculation result into two cases, 4) S
≤
500 and 5) S > 500. For details, refer to ‘
Calculation
Example 1 For use in Europe
’.
For calculating T
m
(maximum halt time of the device), use a special device called a ‘brake monitor’.

When using the floating blanking function, the size of the minimum sensing object becomes larger,
and the equation is changed as follows. Refer to the standard for the detail.
S = K × T + C
