WARNING: Not To Be Used for Personnel Protecꢀon
Never use this device as a sensing device for personnel protecꢀon. 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
applicaꢀons. A sensor failure or malfuncꢀon can cause either an energized or de-energized sensor output
condiꢀon.
Overview
Banner SMI30 Series intrinsically safe barrel sensors are extremely rugged and powerful opposed mode infrared sensor pairs designed
for the most demanding industrial applicaꢀons. Their high excess gain (350 foot range) provides enough sensing power to penetrate the
heaviest contaminaꢀon (see Excess Gain Curve). Electronics are fully epoxy-encapsulated for maximum resistance to mechanical shock
and vibraꢀon. Posiꢀve sealing at both ends, with no exposed epoxy interfaces, eliminates all leak paths (including capillary leakage).
Construcꢀon 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 30 V dc.
SMI30 Series sensors are cerꢀꢁed as being intrinsically safe when used with approved intrinsic safety barriers. SMI30 Series sensors are
suitable for intrinsically safe use in hazardous locaꢀons as listed in the Approvals table (see SMI30 Speciꢀcaꢁons on page 4). SMI30
Series sensors are also cerꢀꢁed as non-incendive devices when used in Class I, Division 2, Groups A, B, C, and D locaꢀons without
intrinsic safety barriers.
SMI30 Series sensors may be wired for either two- or three-wire current-sinking operaꢀon. 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).
Intrinsic safety barriers and current trip point ampliꢁer model CI3RC2 are also available (see Accessories on page 6).
