PROTECTION DISTANCE AND
RANGE OF LIGHT BEAM COVERAGE
If the optical axis (center of the light beams) is aligned
correctly, a detection line with sufficient margin of
sensitivity is formed.

As these sensors are designed to detect humans, install so that the center of the sensors are at a height of
approximately 2.6ft (0.8m) from the ground when installing both on a wall and on a pole.

In order to prevent the intrusion by crawling or climbing over, stack PXB-100ATC in several numbers.

As the infrared light leaves the transmitter, it expands into conic shape light beams.
The optical axis is in the center of the light beams. Arrange the reflector so that the
device on the opposite side is in the center of the light beams.
If the optical axis is not aligned correctly, there will be
insufficient margin of sensitivity even if the receiver is
at the center of the light beams, making the system
more susceptible to adverse effects of the environment
WRONG
resulting in a malfunction.
Installing so that the center of the sensor is
approximately 2.6ft (0.8m) from the ground means that
the protection line is at waist height for humans,
CORRECT
enabling reliable detection.
If the installation position is too high or too low, the
protection line will be above shoulder height or below
knee height, making it more difficult for reliable
WRONG
detection.
Set the sensor about 1ft(0.30m) from the
floor so that it will detect the head of
crawling person.
To prevent a intruder from climbing over
the standard setting beams, set the sensor
at the height upper than standard setting.
