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. Further, the sensing range can be 0.3 to 7m.
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.
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.
