Description
The ultrasonic
switch UPY 300 RA 24 is used instead of a conventional electric wall mounted
switch when a non contact operation is necessary (e.g. sliding doors, lights
etc.). This complies with certain hygienic
requirement in, for example,
the
food processing industry,
hospitals and
clean rooms.
The advantage of
ultrasonic sensors compared to optical switches is that they are less
susceptible to
dirt and
are
fully water
resistant. The sensor diaphragm is protected against mechanical wear by an
orifice. The sensor reacts only to presence and not to movements. As soon as an
object (e.g. a hand) is within the 30cm detection zone, the built-in relay
switches. Since the sensor senses the
time of flight and not an intensity (as usual with optical sensors), it has a
100% background suppression. Loads of up to 30VAC/DC and 6A can be switched with
the mono stable relay.
The UPY switch is
supplied
built
into a
suitable
cover for either wall or surface mount. The precise
cover type
required is specified at the
time of ordering.
If required, covers
can be sent with the order for further processing.
