WARNING

These ultrasonic sensing devices do NOT include the self-checking redundant circuitry necessary to allow their use

in personnel safety applications. A sensor failure or malfunction can result in either an energized or a de-energized sensor output condition.
Never use these products as sensing devices for personnel protection. Their use as safety devices may create an unsafe condition which

could lead to serious injury or death.
Only MACHINE-GUARD and PERIMETER-GUARD Systems, and other systems so designated, are designed to meet OSHA and ANSI

machine safety standards for point-of-operation guarding devices. No other Banner sensors or controls are designed to meet these standards, and they

must NOT be used as sensing devices for personnel protection.

Banner "923" series ULTRA-BEAMs are rugged, reliable ultrasonic

proximity sensors with analog outputs. They are ideal for applications

that require proximity mode distance sensing and a continuous linear

analog output (voltage sourcing or current sinking) throughout an

adjustable sensing range. Typical applications are fill level sensing,

position sensing and guidance, web tensioning and positioning, size

sorting of objects on production lines, and centering control. Banner

ULTRA-BEAM analog outputs interface directly to ordinary voltme-

ters and milliammeters, LED bargraphs, variable speed DC motor

drives, microprocessors, and programmable controllers.
Use of ultrasonics (sound waves, not light) enables Banner ULTRA-

BEAMs to detect objects that are totally undetectable or only margin-

ally detectable by photoelectric (light dependent) methods. ULTRA-

BEAM ultrasonic sensors can reliably detect objects regardless of

their color or transparency to light. Banner analog ULTRA-BEAMs

can sense the presence of clear glass or film just as reliably as they can

detect the presence of a solid metal object of the same profile. When

one of ULTRA-BEAM's analog outputs is connected to an appropriate

instrument (even an accurately calibrated DC voltmeter or milliam-

meter will suffice) the distance from the sensor face to a surface

perpendicular to the sensing axis can be read with accuracy.
"923" series analog ULTRA-BEAMs have a sensing range of 20" to

20', with the response pattern shown in figure A. Easily-accessible 15-

turn clutched potentiometers (NULL and SPAN adjustments, located

on top of the unit) allow the limits to be shifted to create a "sensing

window" of adjustable "depth" anywhere within the 20" to 20' range

(see figure B). The limits of the sensing window can easily be reset

when sensing requirements change.
The maximum depth of the adjustable sensing window is 18'4"; the

minimum depth is 12". Objects beyond the far end of the window are

ignored. Objects within the beam pattern and between the sensor and

the near end of the window, however, will block the ultrasonic beam

and prevent operation. For proper operation, an average target object

should present to the sensor a minimum of 1 square foot of reflective

surface area for every 10 feet of sensing distance.
ULTRA-BEAM's analog outputs may be set to either increase or

decrease with increasing distance to objects that are sensed within the

sensing window. Output that increases with distance from the sensor

is described as having positive slope. Output that decreases with

distance has negative slope (figures E and F, page 4).
"923" series ULTRA-BEAMs have a special relative distance indicat-

ing system, which pulses a top-mounted red LED when an object is

SENSING MODE: ultrasonic proximity
SENSING RANGE: 20 inches to 20 feet at 20°C.

Minimum required target area is 1 square foot (0,1 square meter) for

each 10 feet (3 meters) of sensing range.
SENSING WINDOW ADJUSTMENTS: sensing window depth is

adjustable from 12" to 18'4" via two top-mounted 15-turn clutched

potentiometers with slotted brass elements (NULL and SPAN adjust-

ments). This adjustable window may be placed anywhere within the

20" to 20' sensing range.
OUTPUTS:

Two analog solid-state outputs:

0 to +10V dc (sourcing); minimum 500Ω load

0 to 20mA dc (sinking); 4.0V dc maximum voltage drop

Both outputs may be set for either "positive slope" or "negative slope"
RESPONSE TIME: 100 milliseconds
INDICATOR LED: top-mounted red LED indicator lights when-

ever power is applied to the sensor, and pulses at a 0 to 10Hz rate

which is proportional to analog output voltage (sourcing output) and

current (sinking output)
OPERATING TEMPERATURE RANGE: 0 to 50°C (+32 to

122°F). Maximum humidity 90% (non-condensing conditions).
SUPPLY VOLTAGE:

Model SU923QD: 18 to 30V dc, 5VA

Model SUA923QD: 105 to 130V ac (50/60Hz), 5VA

Model SUB923QD: 210 to 260V ac (50/60Hz), 5VA
CIRCUIT PROTECTION: inputs are protected against polarity

reversal (DC models); both analog outputs are protected against short

circuit of outputs (AC and DC models).
CABLE: 4-pin (for SU923QD) or 5-pin (for SUA923QD and

SUB923QD) Quick Disconnect ("QD") type connectors are stan-

dard. NOTE: use 4-conductor (model MBCC-412) or 5-conductor

(model MBCC-512) SO-type cable, 12 feet long (order separately,

see page 6).
CONSTRUCTION: overall dimensions 4.7"H x 2.0"W x 1.9"D;

rugged molded Valox™ housing; epoxy-encapsulated circuitry.

NEMA 1, 3, and 12. Mounting nut and lockwasher supplied.

output and to the object's position within the sensing window.
