2-3 Protection Area

2-3-1 Sensing Area

The sensing area is the zone formed by the sensing height of the device and the sensing range
between the emitter and the receiver. The sensing height is determined by the number of beam
channels. Furthermore, the sensing range can be 0.3 to 9m for SF4B-H□G<V2> (12 to 64 beam
channels) and SF4B-A□G<V2> (6 to 32 beam channels), 0.3 to 7m for SF4B-F□G<V2> and
SF4B-H□G<V2> (72 to 96 beam channels) and SF4B-A□G<V2> (36 to 48 beam channels).

● 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 al-
ways 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 reflection type or recursive reflection type arrangement.
● Furthermore, facing several receivers towards one emitter, or vice versa, could
produce a non-sensing area or cause mutual interference, which may result in
death or serious injury.
The sensing height is the
area between the line indi-
cated in the top part and line
indicated in the bottom part.
