Protection Area
2-3 Protection Area
2-3-1 Sensing Area
●Be sure to install protection structure around the machine so that the operator must pass through the
sensing area of this device to reach the dangerous parts of the machine.
Furthermore, ensure that some part of the operator’s body always remains in the sensing area when
operation is done with the dangerous parts of the machine. Failure to do so can result in death or
serious injury.
● Do not use any reection type or recursive reection type arrangement.
●Furthermore, never use this device facing several receivers towards one emitter or vice versa.
The sensing area is the zone formed by the sensing height (protective height) of the device and the valid
range between the emitter and the receiver. The sensing height (protective height) is determined by the num-
ber of beam channels. Furthermore, the valid range can be 0.1 to 3m.
Take care that if the valid range is under 0.1m, malfunction may occur due to the optical structure.

2-3-2 Safety Distance
Calculate the safety distance correctly, and always maintain the distance which is equal to or greater
than the safety distance, between the sensing area of this device and the dangerous parts of the ma-
chine. If the safety distance is miscalculated or if sufcient distance is not maintained, the machine will
not stop quickly before reaching to the dangerous parts, which can result in death or serious injury.
The safety distance is the minimum distance that must be maintained between this device and the danger-
ous parts of the machine so that the machine can be stopped before a human body or an object can reach
the dangerous parts.
The safety distance is calculated based on the equation described in the next page when a person moves
perpendicular (normal intrusion) to the sensing area of the device.
Safety distance S
Dangerous
part
Sensing area
Intrusion direction
Before designing the system, refer to the relevant standards of the region where this device is to be
used, and then install this device.
Furthermore, the equation described in the next pages is to be used only in case the intrusion direction
is perpendicular to the sensing area. In case the intrusion direction is not perpendicular to the sensing
area, be sure to refer to the relevant standard (regional standard, specication of the machine, etc.) for
details of the calculation.
The max. response time of the machine is from the point that the machine receives the halt signal from
this device to the point that the dangerous parts of the machine stops. The max. response time of the
machine should be timed with the machine to be actually used.
The size of the minimum sensing object for this device is depending on whether the oating blanking
function is applied or not. Calculate the safety distance with the proper size of the minimum sensing
object and appropriate equation.

● For calculating the safety distance S, there are the following ve cases.
First, calculate by substituting the value K = 2,000 (mm/sec.) 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/sec.). 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.”
●When this device is used in the “PSDI mode,” an appropriate safety distance S must be calculated.

<Calculation example>
● Calculation example 1: For use in Europe
(OFF response time: 7ms or less, minimum sensing object diameter: 25mm)
First, calculate with K = 2,000.
S = K × T + C
= K × (Tm + TSF4C) + 8 × (d - 14)
= 2,000 × (Tm + 0.007) + 8 × (25 - 14)
= 2,000 × Tm + 2,000 × 0.007 + 8 × 11
= 2,000 × Tm + 14+ 88
= 2,000 × Tm + 102
If the result is:
1) In case S < 100 (mm)
Safety distance S is taken as 100 (mm)
2) In case 100 ≤ S ≤ 500 (mm)
Safety distance S is taken as 2,000 × Tm+ 102 (mm)
3) In case S > 500 (mm)
S = K’× (Tm + TSF4C)+ 8 × (d - 14)
= 1,600 × (Tm + 0.007) + 8 × (25 - 14)
= 1,600 × Tm + 1,600 × 0.007 + 8 × 11
= 1,600 × Tm + 11.2 + 88
= 1,600 × Tm + 99.2
then, calculate again.
If the result is:
4) In case S ≤ 500 (mm)
Safety distance S is taken as 500 (mm)
5) In case S > 500 (mm)
Safety distance S is taken as 1,600 × Tm+ 99.2 (mm)
In case this device is installed in a system with a maximum halting time 0.1 (sec.)
S = 2,000 × Tm+ 102
= 2,000 × 0.1 + 102
= 302
Since this value matches with the case 2) above, S is 302 (mm).
In case this device is installed in a system with a maximum halting time 0.4 (sec.)
S=2,000 × Tm+ 102
= 2,000 × 0.4 + 102
= 902
Since this value matches with the case 3) above,
S=1,600 × Tm+ 99.2
= 1,600 × 0.4 + 99.2
= 739.2
Since this value matches with the case 5) above, S is 739.2 (mm).

●Equation 2 DS= K × (TS+ TC+ TSF4C + Tbm) + Dpf
DS : Safety distance (mm)
Minimum required distance between the sensing area surface and the dangerous parts of the
machine
K : Intrusion speed {Recommended value in OSHA is 63 (inch/sec.) [≈ 1,600 (mm/sec.)]}
ANSI/RIA 15.06 does not dene the intrusion speed “K”. When determining K, consider pos-
sible factors including physical ability of operators.
TS : Halting time calculated from the operation time of the control element (air valve, etc.) (sec.)
TC : Maximum response time of the control circuit required for functioning the brake (sec.)
TSF4C: Response time of this device (sec.)
Tbm : Additional halting time tolerance for the brake monitor (sec.)
The following equation holds when the machine is equipped with a brake monitor.
Tbm = Ta - (TS+ TC)
Ta: Setting time of brake monitor (sec.)
When the machine is not equipped with a brake monitor, it is recommended that 20% or more
of (TS+ TC) is taken as additional halting time.
Dpf : Additional distance calculated from the size of the minimum sensing object of the device (mm)
Dpf = 61.2mm
Dpf = 3.4 × (d - 0.276) (inch)
≈ 3.4 × (d - 7) (mm)
d: Minimum sensing object diameter 0.985 (inch) ≈ 25 (mm)
When the floating blanking function is applied, the minimum sensing object becomes large. According to ANSI/RIA
15.06, Dpf = 900mm (3ft) when d > 64mm (2.5 inches).
<Reference>
Since the calculation above is performed by taking 1 (inch) = 25.4 (mm), there is a slight difference between the representa-
tion in (mm) and that in (inch).
Refer to the relevant standard for the details.

<Calculation example>
● Calculation example 2: For use in the United States of America
[OFF response time: 7ms or less, minimum sensing object diameter: 0.985 (inch) ≈ 25 (mm)]
Ds= K × (TS+ TC+ TSF4C + Tbm) + Dpf
= 63 × (Ta+ 0.007) + 3.4 × (d - 0.276) (inch)
= 63 × (Ta+ 0.007) + 3.4 × (0.985 - 0.276)
= 63 × Ta+ 63 × 0.007 + 3.4 × 0.709
= 63 × Ta+ 0.441 + 2.4106
= 63 × Ta+ 2.8516
≈ 63 × Ta+ 2.85 (inch)
In case this device is installed in a system with a maximum halting time 0.1 (sec.)
Ds= 63 × Ta+ 2.85
= 63 × 0.1 + 2.85
= 9.15 (inch)
≈ 232.41 (mm)
Hence, as per the calculations Ds is 232.4 (mm).
Since the calculation above is performed by taking 1 (inch) = 25.4 (mm), there is a slight difference between the repre-
sentation in (mm) and that in (inch).
