Up to 8 Meter Range
Proximity Sensing
Whether the object being detected
is just a few inches from
the
sensor or as far away as 26
feet, or the application calls for a
specific
sensor configuration, the
SUPERPROX® Model SM900 series
of ultrasonic
sensors offers a
variety of proximity sensing solutions.
There is the mounting convenience
of a 30 mm housing,
sensing ranges of 1 m (39"), 2 m
(79"), and a long-range 8 m (26'),
the shortest deadbands in the
sensing industry, and unique factory
configurability to meet the
user’s needs. In addition to sensing
ranges, model selections include
normally-open or normallyclosed
NPN and PNP outputs,
complementary NPN or complementary
PNP outputs, and a variety
of response times and default
sensing window setup limits. By
using the Model Reference Guide
to select the specific model required,
the user is assured of a
reliable, cost-effective proximity
sensing solution for a multitude of
applications.
All models in this series are
equipped with a push-button to set
the limits for the sensing “window.”
When it is impractical to use the
push-button for setting long-range
sensing limits, an optional, handheld,
setup/display accessory is
available. All limits are stored in
nonvolatile memory and thus are
retained if power is removed from
the
sensor.
The
sensors are available in either
ULTEM® plastic or SS303
stainless steel housings. Both
housings are sealed to withstand
dusty, dirty, clean-in-place, noncondensing
humidity, and highpressure
washdown environments.
Unlike other sensing technologies,
these
sensors are capable
of detecting all materials regardless
of color, shape, and composition
(transparent or opaque,
liquid or solid) including clear
glass, powder, food products,
metal, plastics, and objects that
change colors. They are virtually
unaffected by changing light conditions,
colors, and noise. Packaged
in a 30 mm, threaded housing
with jam nuts, the Model
SM900
sensors are easily
mounted in normally tough-to-install
areas of the plant. With protection
ratings of NEMA 4X (indoor
use only) and IP67, the
sensors
resist most acids, bases,and
oils, including most food products.
All the
sensors in this
model series are CE certified. Additionally,
the Model SM900 series
sensors offer compatible integration
with most programmable
logic controllers.
