Banner SMI30 Series intrinsically safe barrel sensors are extremely rugged and
powerful opposed mode infrared sensor pairs designed for the most demanding
industrial applications. Their high excess gain (460 foot range) provides enough
sensing power to penetrate the heaviest contamination (excess gain curve, page 5).
Electronics are fully epoxy-encapsulated for maximum resistance to mechanical
shock and vibration. Positive sealing at both ends, with no exposed epoxy interfaces,
eliminates all leak paths (including capillary leakage). Construction exceeds NEMA
6P (IEC IP 67) standards. Sensors are approximately 1.2" in diameter by 4" long.
SMI30 series dc receivers operate from 10 to 30V dc. These sensors carry entity
approval from
Factory Mutual Research
and
CSA
for intrinsically safe operation in
hazardous atmospheres. SMI30 Series sensors are certified as being intrinsically safe
when used with approved intrinsic safety barriers. SMI30 Series sensors are suitable
for intrinsically safe use in hazardous locations as defined by Article 500 of the
National Electrical Code (see classifications, above right). SMI30 Series sensors are
also certified by Factory Mutual and CSA as non-incendive devices when used in
Division 2 locations (except Groups E and F) without intrinsic safety barriers.
SMI30 Series sensors may be wired for either two- or three-wire current-sinking
operation. In the three-wire hookup, which requires two intrinsic-safety barriers (or
one dual barrier), the sink current is 15mA. The two-wire hookup, which requires one
barrier, sinks
≤10mA
(OFF state) and
≥20mA
(ON state).
Intrinsic safety barriers are available from Banner (see page 5). Current trip point amplifier
CI3RC2 is also offered (page 4). Several mounting brackets are available (see page 6).

WARNING
These photoelectric presence sensors 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.

SMI30 Series Intrinsically Safe Sensors
SMI30 Series receivers have a red LED alignment indicator that lights
whenever the receiver "sees" its modulated light source. Emitters have
a red LED to indicate "power on". All LED indicators are mounted
internally to preserve the waterproof integrity of the sensor housing, and
are visible from both the side and front of the sensor through the sensor's
quad-ring sealed acrylic lens.
The innovative circuitry used in SMI30 Series emitters and receivers
provides the best noise immunity of any self-contained opposed mode
sensor pair. For applications where optical crosstalk between sensors
might be a problem, SMI30 Series emitters and receivers are available
with a choice of three modulation frequencies (frequency "A",
frequency "B", or frequency "C"). This makes it possible to use high-
powered sensor pairs of different frequencies in close proximity to
each other without crosstalk. (NOTE: frequency "A" is standard;
frequencies "B" and "C" are available by special order. An emitter and
its receiver must be of the same modulation frequency.) See the chart
on page 5 for a summary of models.
Each unit is supplied with two hexagonal jam nuts. A 30mm clearance
hole is required for mounting, and mounting bracket models
SMB30MM, SMB30S, and SMB30C are available (page 6). All
models have a built-in standard quick-disconnect ("QD") connector.
"QD" models mate with 12-foot long model SMICC-312 or 30-foot
long model SMICC-330 mini-type QD cable (sold separately from
sensor).

Hookup Information
SMI30 Series sensors are certified intrinsically safe ONLY
when used with certified energy-limiting intrinsically safe
barriers. Emitter units use a two-wire hookup (there is no output
connection). Note from the hookup diagram (page 3) that the
receiver installation may be made using either a single barrier
(2-wire hookup) or with a dual channel barrier (3-wire hookup).
In the 2-wire configuration, the sensor acts as a current sink,
drawing less than 10mA in the OFF state and more than 20mA
in the ON state. The customer must provide a current sensing
device ("current sensor" in the diagram) to convert the current
to a logic level. SMI30 Series sensors may be used with Banner
Current Amplifier Control Module CI3RC2.
The CI3RC2 module may be purchased (with model RS-11
module socket, one dual-channel barrier, and DIN rail barrier
mounts included) by specifying kit model CI2BK-2. One dual-
channel intrinsic barrier (alone) may be ordered by specifing
model CI2B-1. See the photo, page 5.
In the 3-wire configuration, the output may be used directly to
control loads of less than 15mA.
In selecting the barrier, it is important to consider the barrier's
resistance.
The sensors must have at least 10 volts across the
brown and blue power leads for proper operation, and the
barrier will cause a voltage drop due to its resistance.
The
formula that determines how much resistance is allowed is:
Cable connector (female,
for SMICC cable,
side view)
Note that, in the 3-wire hookup, the barrier is in series with the
load. This results in an apparent saturation voltage of the output
that is higher than the sensor output by the amount of IxR
(current times voltage) drop through the barrier.
Emitters use the 2-wire hookup; receivers use either 2- or 3-wire
hookup. See the chart (page 5) for a summary of models.
Barriers are generally classified as either "positive input" or
"negative input". SMI30 Series intrinsically safe sensors re-
quire "positive input" barriers for both supply and load. The
blue (negative supply) lead of the sensor is normally connected
to the ground terminal of the barrier.
The user of this equipment is responsible for proper installation
and maintenance of the equipment, and must conform with the
certification requirements relating to barriers and to maximum
allowable capacitance and inductance of the field wiring. If you
are in doubt about these requirements, our applications engi-
neers can refer you to the appropriate authority.
R = 40 (supply voltage - 10 volts).
If the supply voltage is 24V dc, then the maximum resistance is
560 ohms. If the supply voltage is 18V dc, then the maximum
resistance is 320 ohms. This includes the resistance of any
current sensing device used (in the 2-wire configuration), so the
barrier resistance must be further reduced by the current sensor
resistance.

CI3RC2 Module
Banner MAXI-AMP module model CI3RC2
(part number 36606)
is a self-contained module which converts the current output signal
of an SMI30 Series sensor to a trip point switch.
Both sensors of the opposed mode pair are wired to model CI3RC2
using the two-wire hookup, which requires the use of two single
channel or one dual channel intrinsic safety barrier(s). In this mode,
the SMI30 receiver sinks
≤10
milliamps in the "OFF" state and
≥20
milliamps in the "ON" state. The CI3RC2 senses this current change
and switches internal relays which are easily wired to most loads and/
or additional control circuitry.
Model CI3RC2 is powered by either 105-130 or 210-250V ac. The
CI3RC2 supplies power to operate both the emitter and receiver.
Inputs are protected against short circuits. Built-in circuit diagnos-
tics indicate an overload of either input by pulsing an LED status
light.
The CI3RC2 module has two isolated output switches. There is a 5
amp rated SPDT electromechanical relay, and a solid-state transistor
switch which may be used for logic-level interfaces.

APG30S Aperture Kit for SM30 Series Sensors
(27533)
These new water-tight aper-
tures for SM30 Series sen-
sors may be used to size and
shape the effective beam or
to limit excess gain for avoid-
ing "burn-through" effects.
Apertures are sold as a kit,
which includes a thread-on
stainless steel housing, a flat
glass lens, two quad-ring
seals, and 3 round and 3 slot-
ted aperture disks.
The stainless steel aperture
housing functions equally
well with VALOX
®
and stain-
less steel sensor models. The
glass lens is useful for pro-
tecting the SM30's acrylic
lens against substances that
are hostile to acrylics, such
as concentrated acids and alkalis and industrial solvents.
Aperture sizes include the following.
Round: .06", .12", and .70" diameter
Slotted: .04", .10", and .20" wide
