Glossary
Slave
That
USi
of a
multisensor
, which receives the synchronisation signal
SYNC
from
the
master
.
s
min
Formula for the
minimum switching distance
.
Sensor
Proximity switch
, which operates in the basic function
measurement
. Here, the
objective of the evaluation of the
echo signals
is to determine the distance of the
detected
objects
. The measurement result is available at the analog output OUT 1.1
as a current signal (USi-IP) or voltage signal (USi-UP).
(cf.
Measurement, Switch
)
Sensor
Part of the
USi
, which can transmit the ultrasonic waves via the
active surface
and
receive resulting echos. Up to two sensors can be connected to each
USi
. The
connection designations on the
Evaluation Unit
are in English. (cf.
Ultrasonic trans-
ducer
,
transducer
; BUT:
sensor
)
Sonic barrier
Extended function of an
ultrasonic proximity switch
. Two
sensors
face each other
and monitor the taught-in area in between. One
sensor
thereby acts as a
transmit-
ter
and the other as a
receiver
. Each change results in signal change at the
output
.

ex barrier
)
Sonic lobe
Three-dimensional
coverage range
of a
ultrasonic proximity switch
.
Supply voltage
Voltage, which is externally connected to a device, in order to enable its operation.
The supply voltage should correspond to the connecting voltage indicated on the
type plate of the device.
SYNC
Signal for the synchronisation of a
multisensor
.
Switch
Proximity switch
, which operates in the basic function
measurement
. The objective
of the evaluation of the
echo signals
is only to determine the two conditions “object
present” and “object not present”. (cf.
Detection, Sensor
)
Switching behaviour
USi parameter which de
fi
nes the switching characteristic at the outputs. The switch-
ing characteristic is preset as a switch in delivery condition. In the case of a switch-
ing behaviour as a switch, the outputs function as normal switches. In the case of
a switching behaviour as a button, the outputs function according to time periods: if
an object is detected, the outputs react and remain in this state for the period T
ON
.
The USi then pauses for the time period T
OFF
. The outputs are reset during this time.
Switching distance
Distance
, at which a signal change at the output is caused by the approxima-
tion of a
measurement object
to the
active surface
along the
reference axis
.

Switching frequency
Number of switching operations of a proximity switch in a speci
fi
ed time interval.
