Sensing
Sensing full or empty case
conditions is greatly simplified
with these SUPERPROX
®
sen-
sor models. Other typical appli-
cations include sensing height
differentiation, detecting object
surfaces in specific areas, and
performing on-demand and
automation-control sensing
functions.
The SUPERPROX
®
Model
SM504B (cable style) and Model
SM554B (connector style) se-
ries of ultrasonic, proximity sen-
sors, when used in a set, pro-
vide for external control of the
pulsing of all the sensors. A
setup switch in these sensors,
designated “Master” and “Slave,”
selects the operating technique
• Allows sensors
to operate in close
proximity
• Detects objects at
specific points within
adjustable “window”
limits
• Makes profiling and
positioning
applications possible
• A push-button sets
window limits
• Operating range up to
2 m (79")
• CE certified
to either simultaneously synchro-
nize or gate the transmit and re-
ceive cycles of a multiple sensor
set. This unique concept is an ef-
fective solution for applications
such as: full or empty case in-
specting, on-demand controlled
sensing or inspecting, in-case
container counting, automation
control sensing, object-in-area
sensing, down container sensing,
differential height inspecting, and
more.
The synchronized technique is
designed for applications requir-
ing continuous “curtain” sensing
over a wide area. Synchronized
sensing allows any number of sen-
sors to be operating close to-
gether, thus eliminating any pos-
sible adverse ultrasonic signal in-
terference between the sensors.
Controlled or multiplexed sens-
ing of multiple objects, locations
or surfaces is accomplished us-
ing the gated technique. With this
technique, PLS and PLC output
switches or other sensing devices
may be used to trigger or gate a
sensor set. Depending on the ap-
plications, a set of these sensors
is used with an isolated switching
device to prevent possible false
sensor outputs due to changing
foreground object conditions.
Like other SUPERPROX
®
sen-
sors, these models have the ca-
pability to detect objects at spe-
cific points within adjustable “win-
dow” limits, thus making profiling
and positioning applications pos-
sible. A push-button sets the win-
dow limits. The sensors carry the
CE Mark and are epoxy sealed in
a tough plastic housing to resist
harsh, wet, or dirty environments
typically associated with the above
applications. The housing meets
NEMA 4X (indoor use only) and
IP67 industry standards. A Dairy
3A compliant housing is available
as an option. These sensors have
operating ranges of 51 to 635 mm
(2 to 25"), 51 to 1 m (2 to 39") and
120 mm to 2 m (4.7 to 79") and are
available in 12 to 24 VDC model
versions.
