Protection Area

2-3 Protection Area

2-3-1 Sensing Area

● Be sure to install a protection structure around the machine so that the operator must pass
through the sensing area of the device to reach dangerous parts of the machine.
Ensure that part or all of the operator's body remains in the sensing area when the operator
works with dangerous parts of the machine. Risk of death or serious injury if the operator's body
is not detected.
● Do not use in a reflective type or recursive reflective type setup.
● Multiple receivers (emitters) cannot be connected for use with a single emitter (receiver).
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 of the device is determined by the number of beam channels.
The sensing range of the SF4D-F□ is 0.2 to 7m (0.8 to 12m in long mode). The sensing range
of the SF4D-H□ and SF4D-A□ is 0.2 to 9m (0.8 to 15m in long mode).
If used at less than 0.2m (less than 0.8m in long mode), optical system effects may cause mal-
functioning.

The sensing height (pro-
tection height) is the length
from the top to the bottom
of the device.
