Method for calculating the safety distance as provided by
ANSI B11. 19 (US)
Safety distance (S) = Intrusion speed into the detection zone (K)
* The light curtain response time refers to the time required for output

Method for calculating the safety distance as provided by
ANSI/RIA R15.06 (US) (for intrusion perpendicular to the
detection zone)
Safety distance (Ds) = K × (Ts + Tc + Tr) + Dpf

to change from ON to OFF.
Response time (Ts + Tc + Tr + Tbm) + Additional distance (Dpf)
Where:
K = Intrusion speed (Recommended value in OSHA standards
Ts = Time required for machine to stop (s)
Tr = Light curtain response time (s) *
Tc = Maximum response time required for machine control
Tbm = Additional time (s)
Dpf = Additional distance. Dpf is calculated as follows based on
Example:
Assume that: K = 1,600 mm/s, Ts + Tc = 0.06 s,
Brake monitor setting time = 0.1s, Tr = 0.01s, d = 14 mm.
Then:
Tbm = 0.1 – 0.06 = 0.04 s
Dpf = 3.4 – (14 – 7.0) = 23.8 mm
S = 1,600 × (0.06 + 0.01 – 0.04) + 23.8 = 199.8 mm
Where:
K = Intrusion speed: 1,600 mm/s min.
Ts = Maximum stop time of machine/equipment (s)
Tc = Maximum stop time of control system (s)
Tr = Light curtain response time (s) *
Os = Diameter of the smallest detectable object (mm)
Dpf = Additional distance (mm)
Assume that the sensor is installed with the lowest beam height
above the floor at 300 mm and the highest beam height above the
floor at 1,200 mm, with the diameter of the smallest detectable
object being 64 mm or less. Then, Dpf is determined from:
Dpf = 3.4 × (Os – 6.875 mm).
If the diameter of the smallest detectable object is more than
64 mm, Dpf is calculated to be 900 mm.
Example:
Assume that K = 1,600 mm/s, Ts + Tc = 0.06 s, Tr = 0.01 s,
and Os = 40 mm.
Then:
S = 1,600 × (0.06 + 0.01) + Dpf
Assume that K = 1,600 mm/s, Ts + Tc = 0.06 s, Tr = 0.01 s,
and Dpf = 900 mm.
Then:
S = 1,600 × (0.06 + 0.01) + 900

ANSI B11. 19. does not define Intrusion speed (K). When
determining K, consider possible factors including physical
ability of operators.

ANSI standards.
Dpf = 3.4 × (d – 7.0)
: d is the detection capability of the light curtain (mm).
If the machine is provided with a brake monitor, Tbm =
brake monitor setting time – (Ts + Tc). If not provided with a
brake monitor, it is recommended to determine a value
more than 20% of (Ts + Tc) as the additional time.

Method for calculating safety distance as provided by
European Norm EN999 (for intrusion perpendicular to the

Substitute K = 1,600 mm/s and C = 850 mm in equation (1) and
calculate as shown below.

S = 1,600 mm/s × (Tm + Ts) + 850
Where:
S = Safety distance (mm)
Tm = Machine response time (s) *1
Ts = Sensor response time (s) *2
Example:
Tm = 0.05 s, Ts = 0.01 s:
S = 1,600 mm/s × (0.05 s + 0.01 s) + 850 mm = 946 mm

hazardous part of the machine stops. The machine response time
should be measured on actual machines. The machine response
time should be measured and confirmed periodically.
