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. 4-47

Sensor Configuration
Switches
Switch 1 configures the sensor to op-
erate in either a normal or high sensitiv-
ity mode. Place this switch in the NORM
position for sensing liquid or solid mate-
rials. Place the switch in the HIGH posi-
tion for sensing soft or porous materials
that will absorb some of the ultrasonic
energy.
Switch 2 configures the sensor to op-
erate in either an object or background
sensing mode. Place this switch in the
OBJCT position to perform a sensing
function for receiving the reflected ultra-
sonic energy directly off an object. Place
this switch in the BKGRD position to
perform a break-beam sensing function
for receiving the reflected ultrasonic en-
ergy directly off a fixed background tar-
get.
Switch 3 selects the operating mode
for the sensor output to be either nor-
mally open (N.O.) or normally closed
(N.C.).
Switch 4 configures the sensor to per-
form either a slave or master operating
function. See Synchronized Sensing and
Gate-controlled Sensing descriptions for
selecting the proper switch position.
Control Compartment
A unique feature available to the user
of these sensors is the ability to quickly
set up each sensor for a specific appli-
cation.The sensor is configured through
four slide switches and a push-button
Synchronized Sensing
Synchronized sensing is a unique fea-
ture of this sensor that enables reliable
“curtain” sensing or inspecting over a
wide area by using multiple sensors in
a set. Synchronized sensing allows
these sensors to be operated close to-
gether, thus eliminating any possible
adverse ultrasonic signal interference
between the sensors.
Any number of these sensors can be
operated together to perform a synchro-
nized sensing function. It is accom-
plished by simply connecting together
the external control wire lead from all
the sensors in the set as shown in the
illustration on the next page. One of the
connected sensors must operate with
setup Switch 4 in the “Master” position
and the other connected sensors must
operate with setup Switch 4 in the
“Slave” position.The designated “Mas-
ter” sensor continuously synchronizes
the transmit and receive cycles of all
the connected sensors as a result of
this configuration.

Sensor Limits Setup
Push-button
First, during installation make sure the
sensor face is as parallel as possible
to the surface of the material being de-
tected.
To set the limits, simply place an ob-
ject at the desired distance from the
sensor for one limit and press the
LIMITS push-button once.This sets the
first limit and switches the sensor out-
put to an inactive state during the limit
setup.While the LIMITS push-button is
depressed, the multicolored LED lo-
cated on top of the sensor, is amber.
Upon release of the push-button, the
LED flashes amber indicating that the
second limit needs to be set within 30
seconds. Place an object at the desired
position for the second limit and press
the LIMITS push-button once. Again
while the push-button is depressed, the
LED is amber. Upon release of the
push-button, the LED flashes amber
momentarily and then turns green to
indicate acceptance of both limits. If 30
seconds elapse before the second limit
is set, the limits revert back to the pre-
vious settings.
At the same time, the sensor output
switches from the inactive to the ac-
tive state, placing the sensor into the
operational mode, ready to use. When
power is off or interrupted, the limits
are retained in a nonvolatile memory.
If in setting either limit the echo from
the object is too weak or distorted, the
LED flashes RED for 10 seconds (or
until the button is pressed again) indi-
cating the limit setting was not accepted
by the sensor. Attempt to set both lim-
its again, being careful to keep the ob-
ject surface parallel to the face of the
sensor.
Minimum allowed distance between
any two setup limits is 13 mm (1/2").
The multicolored LED flashes RED af-
ter the press and release of the LIM-
ITS push-button for the second limit
setting if the distance between the limit
settings is less than 13 mm.The multi-
colored LED continues flashing RED ei-
ther until the LIMITS push-button is
pressed and released once for the first
limit setting or until 10 seconds have
elapsed. Pressing and releasing the
LIMITS push-button once reinitiates the
limit setup sequence. If 10 seconds
elapse before the LIMITS push-button
is pressed and released for the second
limit setup, the limits revert back to the
previous settings.
A special feature provides an auto-
matic 13 mm (1/2") window limits setup
function. Simply place an object within
the sensing range of the sensor and
press the LIMITS push-button twice in
succession without moving the object.
A limit is set on a line 1/4" in front and
back of the object surface nearest the
sensor.
Multicolored LED Indicator
During Limit Setup
Prior to pressing LIMITS push-
button:
• Off - Sensing no object or
object is outside of the
sensing range
• Red - Sensing an object out
side the set limits
• Green - Sensing an object
inside the set limits
LIMITS push-button depressed for
first time:
• Amber - sensing a good object
surface condition
• Red - Sensing no object or a
poor object surface condition
LIMITS push-button released for
first time:
• Flashing Amber - First limit
accepted,waiting for second
limit
• Flashing Red - First limit not
accepted; retry setting limit
LIMITS push-button depressed for
second time:
• Amber - Sensing a good
object surface condition
• Red - Sensing no object or a
poor object surface condition
LIMITS push-button released for
second time:
• Green or Red - Second limit
accepted
• Green or Amber - Second
limit accepted
• Flashing Red - Second limit
not accepted; retry setting
both limits
Multicolored LED Indicator
in Operational Mode
• Off - Sensing no object or
object is outside the sensing
range
• Red - Sensing as object
outside the set limits
• Green - Sensing an object
inside the set limits
Red LED Indicator in
Operational Mode
The red LED serves as a visual
indicator for the sensor output. The
LED is illuminated when the output
is in an active (ON) state. Note:
Indicator is not provided on all
models.

Gate-controlled Sensing
Gate-controlled sensing is another
unique feature that enables this sensor
to perform periodic sensing of multiple
objects or locations. Depending on the
application, one or a set of these sen-
sors is used with an isolated switching
device for preventing possible false
sensor outputs due to changing fore-
ground object conditions. Devices such
as SUPERPROX®sensors, program-
mable limit switches or other proximity
sensor switches with an open-collec-
tor, current sinking output are typically
used to perform the isolated gate-switch
or “Master” sensor function.
Gate-controlled sensing is accom-
plished by connecting the external con-
trol wire lead from each sensor to the
DC supply voltage common through the
isolated switch as shown in the illus-
tration on the next page. Each con-
nected sensor must operate with setup
Switch 4 in the “Slave” position. In this
configuration, the sensors simulta-
neously transmit and receive ultrasonic
energy only when the gate device is
switched to the ON or CLOSED state.
When the gate device is switched back
to the OFF or OPEN state, the sensor
outputs are latched from changing state
until the next gate-switch cycle.
