Printed in USA 11/06 P/N 35331 rev. B • ••• • • • 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). Specifications Designed for use with approved amplifiers and intrinsically safe barriers in explosive environments Very high excess gain; 460 ft. range (standard 10 ms models) Fast 1 ms response models (200 ft. range) available by special order Totally sealed, self-contained, intrinsically safe threaded-barrel opposed mode sensor pairs in rugged 30 mm PBT housings Highly immune to noise: the best noise immunity of any selfcontained emitter/receiver pair Internal alignment indicator LED may be viewed either from the side or from the front of the receiver through the lens Integral mini-type 3-pin "QD" (quick-disconnect) connector 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. ! (continued on page 2) Banner SMI30 Series Intrinsically Safe Sensors are designed to meet the following standards: UL 913 CSA 22.2 #142-M1987 FM 3610 UL 1604 CSA 22.2 #157-92 FM3611 UL 508 CSA 22.2 #213-M1987 SMI30 Series sensors, shown with Intrinsic Safety Kit (see page 5).
