Precautions for All Safety Sensors
Note: Refer to the “Safety Precautions” section for each Sensor for specific precautions applicable to each Sensor.
Installation Conditions
Detection Zone and Intrusion Path
Safety Distance
The safety distance is the distance that must be set between the
Safety Light Curtain and a machine's hazardous part to stop the
hazardous part before a person or object reaches it. The safety
distance varies according to the standards of each country and the
individual specifications of each machine. In addition, the calculation
of the safety distance differs if the direction of approach is not
perpendicular to the detection zone of the Safety Light Curtain.
Always refer to relevant standards.
Correct Installation
A person can only reach the
hazardous part of the machinery
by passing through the sensor's
detection zone.
Incorrect Installation
A person can reach the hazardous
part of the machinery without
passing through the sensor's
detection zone.
Install a protective structure so that the hazardous part of
a machine can only be reached by passing through the
sensor's detection zone. Install the sensors so that part
of the person is always present in the detection zone
when working in a machine's hazardous areas.
If a person is able to step into the hazardous area of a
machine and remain behind the Safety Light Curtain's
detection zone, configure the system with an interlock
function that prevents the machine from being restarted.
Otherwise it may result in heavy injury.
Install the interlock reset switch in a location that
provides a clear view of the entire hazardous area and
where it cannot be activated from within the hazardous
area.
The Safety Light Curtain cannot protect a person from an
object flying from a hazardous area. Install protective
cover(s) or fence(s).

Safety distance (S)
Correct Installation
A person enters the detection zone
during operation.
Incorrect Installation
A person is between the sensor's
detection zone and the hazardous
part of the machinery.

How to calculate the safety distance specified by International
standard ISO13855-2002 (European standard EN999-1999)
(Reference)
If a person approaches the detection zone of the Safety Light Curtain
perpendicularly, calculate the safety distance as shown below.
S = K x T + C . . . Eq. (1)
<System that has detection capability of 40 mm max.>
Use K = 2,000 mm/s and C = 8 x (d - 14 mm) in equation (1) for the
calculation.
S = 2,000 mm/s x (Tm + Ts) + 8 x (d - 14 mm)
* These values differ depending on the Switch. Refer to the
[Calculation example]
When Tm = 0.05 s, Ts = 0.01 s, and d = 14 mm:
S = 2,000 mm/s x (0.05 s + 0.01 s) + 8 x (14 mm - 14 mm)
= 120 mm . . . Eq. (2)
If the result is less than 100 mm, use S = 100 mm.
If the result exceeds 500 mm, use the following equation
where K = 1,600 mm/s.
S = 1,600 mm/s x (Tm + Ts) + 8 x (d - 14 mm) . . . Eq. (3)
If the result of this Eq. (3) is less than 500 mm,
use S = 500 mm.
Make sure to secure the safety distance (S) between the
Safety Light Curtain and the hazardous part. Otherwise,
the machine may not stop before a person reaches the
hazardous part, resulting in serious injury.
“Precautions for Correct Use” for the Switch you are using.
S: Safety distance
K: Approach speed to the detection zone
T: Total response time of the machine and Safety Light Curtain
C: Additional distance calculated by the detection capability of the
Safety Light Curtain
S = Safety distance (mm)
Tm = Machine's response time (s)
Ts = Response time of the Safety Light Curtain from ON to OFF (s) *
d = Size of Safety Light Curtain‘s detection capability (mm) *
the machine receives a stop signal to when the machine's
hazardous part stops.
Measure the response time on the actual system. Also,
periodically check that the response time of the machine has
not changed.
