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 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 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. The sensing range can be 0.2 to 13m for the wiring synchronization using 8-core ca-
ble 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 under 0.2m, malfunction may occur due to the optical structure.
