It emits light to the receiver facing it. Furthermore, the status of the emitter and the receiver is indicated on its display section.
<Receiver>
It receives light from the emitter facing it. Simultaneously, it turns ON the control output (OSSD 1, OSSD 2) when the all beam channels receive light from emitter, and it turns OFF the control output (OSSD1, OSSD2) when one or more beam channels are blocked light. Besides, the receiver displays its status on the display section.
<Beam channel>
The light emitting elements of the emitter and the light receiving elements of the receiver are placed at the following intervals, 20mm (SF2B-H ) and 40mm (SF2B-A ).
<Standard mounting bracket (optional)>
This bracket is to be used for mounting the emitter / receiver. It enables to adjust the horizontal mounting angle using the standard mounting bracket.
<Intermediate supporting bracket (For rear mounting) (For side mounting)>
This bracket is to be used for mounting the sensor. SF2B-H is for the sensor having 40 beam channels or more, SF2B-A is for 20 beam channels or more.

Display section:
Notes: 1) Since the color of the operation indicator changes according to ON/OFF status of the control output (OSSD 1, OSSD 2), the operation indicator is marked as ‘OSSD’ on the sensor.
2)The threshold where the control output (OSSD 1, OSSD 2) changes from OFF to ON is applied as ‘100% incident beam intensity’.
3)The status ‘when light is blocked’ refers to the status that the some obstacle is existed in the sensing area.
4) The description given in [ ] is marked on the sensor.

1-3 Protection Area
1-3-1 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 serious injury or death.
Do not use any reflection type or recursive reflection type arrangement.
When connecting the sensor, use the correct combination of emitter and receiver (same beam pitch and number of beam channels) and match their top-bottom orientation. Combining different types of emitter and receiver could produce a non-sensing area, which may result in serious injury or death.
Furthermore, facing several receivers towards one emitter, or vice versa, could produce a non-sensing area or cause mutual interference, which may result in serious injury or death.
The sensing area is the zone formed by the sensing height of the sensor and the sensing range between the emitter and the receiver. The sensing height is determined by the number of beam channels. The sensing range can be 0.2 to 13m for the wiring synchronization using 8-core cable and 0.2 to 5m for the beam synchronization using 4-core cable. Take care that the sensing range becomes short after mounting either protection cover (FC-SF2BH- ) (optional). Take care that if the sensing range is less than 0.2m, malfunction may occur due to the optical structure.

1-3-2 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 machine. If the safety distance is miscalculated or if sufficient distance is not maintained, the machine will not stop quickly before reaching to the dangerous parts, which can result in serious injury or death.
The safety distance is the minimum distance that must be maintained between the light curtain and the dangerous 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 area sensor.

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, specification 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 part of the machine stops. The max. response time of the machine should be timed with the machine to be actually used.

<Reference>
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 For use in Europe’.
For calculating Tm (maximum halt time of the device), use a special device called a ‘brake monitor’.
When this device is used in the ‘PSDI Mode’, an appropriate safety distance S must be calculated. For details, be sure to refer to the standards or regulations applicable in each region or country.

|
|
=1,600 Tm+1,600 0.015+104 |
|

Tm+128 |
then, calculate again. If the result is:

Safety distance S is taken as 500 (mm)
5)In case S>500 (mm)
Safety distance S is taken as 1,600 Tm+128 (mm)
In case this device is installed in a system with a maximum halting time of 0.1 (s) S=2,000 Tm+134
=2,000 0.1+134 =334
Since this value matches with Case 2) above, S is 334 (mm).
In case this device is installed in a system with a maximum halting time of 0.4 (s) S=2,000 Tm+134
=2,000 0.4+134 =934
Since this value matches with Case 3) above, S=1,600 Tm+128
=1,600 0.4+128 =768
Since this value matches with Case 5) above, S is 768 (mm).
