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,
Specifications
SUPPLY VOLTAGE:
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.
Emitters: 10 to 30V dc at 25mA.
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.
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, 10-30Vdc. Two-wirehookupsinks≤10mA
(OFF state) and ≥20mA (ON state), 10-30V dc.
Outputs are short-circuit protected.
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).
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.

CI3RC2 is also offered (page 4). Several mounting brackets are available (see page 6).

INDICATOR: InternalredLEDlightswhenever 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.

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-GUARDandPERIMETER-GUARDSystems,andothersystemssodesignated,
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.
