Banner SMI30 Series—Intrinsically Safe - Manual

Rugged, NEMA 6P-plus sensors in 30 mm threaded PBT barrel housings
• Designed for use with approved amplifiers and intrinsically safe barriers in explosive
environments
• Very high excess gain; 350 foot range (standard 10 ms models)
• Fast 1 ms response models (152 foot 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 self-contained 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: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to serious
injury or death. This device does NOT include the self-checking redundant circuitry necessary to allow its
use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-
energized sensor output condition.
Overview
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 (350 foot range) provides enough sensing power to penetrate the
heaviest contamination (see Excess Gain Curve). 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 inches in diameter by 4 inches 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 ap-
proved 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 15 mA. The two-wire hookup, which requires one barrier, sinks ≤ 10 mA
(OFF state) and ≥ 20 mA (ON state).
