The synchronisation between the emitting diodes and the receiver sensors
is provided by an extra beam emitted by the receiver unit towards the emitter
unit. This synchronisation beam delimits one side of the detection zone (see
figure 1).
When an opaque object with a diameter greater or equal to the resolution
of the system interrupts one or several beams (figure 2), the receiver output
provides an alarm signal to command the control unit to de-energize the
output relays.
The resolution corresponds to the size of the smallest object The resolution corresponds to the size of the smallest object The resolution corresponds to the size of the smallest object The resolution corresponds to the size of the smallest object
that can be detected within the protection zone, obscuring at that can be detected within the protection zone, obscuring at that can be detected within the protection zone, obscuring at that can be detected within the protection zone, obscuring at
least one beam (figure least one beam (figure least one beam (figure least one beam (figure 2). 2). 2). 2).
The resolution is always the same in the protection zone, whatever the
scanning range may be since it only depends on the lens diameter and the
lens pitch.
