SMI30 Series Intrinsically Safe Sensors
Rugged, NEMA 6P-plus sensors in 30 mm threaded PBT barrel housings
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).
SUPPLY VOLTAGE:
Emitters: 10 to 30V dc at 25mA.
Receivers: 10 to 30V dc at 15mA max. Division 1 use,
with barriers, requires minimum system supply voltage
of 10V. See hookup information, pages 3-4.
OUTPUT:
Receivers only: Current sinking NPN open-collector
transistor. Three-wire hookup sinks 15mA maximum
continuous, 10-30V dc. Two-wire hookup sinks 10mA
(OFF state) and 20mA (ON state), 10-30V dc.
Outputs are short-circuit protected.
SENSING BEAM: 880 nanometers, infrared;
effective beam size 0.75" diameter.
RESPONSE TIME: 10 milliseconds on/off (models
with 1ms response are available by special order)
REPEATABILITY: See chart, page 5
Response Time and Repeatability specifications are
independent of signal strength.
INDICATOR: Internal red LED lights whenever the
receiver sees its modulated light source. Emitters
have red "power on" indicator LED. All indicators are
visible through the lens or from side of the sensor.
CONSTRUCTION: NEMA 6P, IEC IP67.
30mm diameter tubular threaded PBT hous ing,
positive sealing at both ends; quad-ring sealed acrylic
lens. Electronics are fully epoxy encapsulated. Two
PBT jam n uts are provided.
CABLE: Three-wire mini-type QD cable (12 ft. long
model SMICC-312 or 30 ft. long model SMICC-330).
Cable electrical properties: 40pf/ft.; .20ìH/ft.
Order cable separately from sensor.
MOUNTING ALTERNATIVES:
30mm clearance hole;
SMB30C split clamp mounting bracket (page 6);
SMB30MM two-axis mounting bracket (page 6);
SMB30S swivel mounting bracket (page 6).
OPERATING TEMPERATURE RANGE:
-40 to +70°C (-40 to +18°F).

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.
