VALU-BEAM®SMI912 Series Sensors
Certifications
Supply Voltage and Current 10 to 30V dc for sensor, 25 mA maximum
Division 1 use, with barriers, requires a minimum system supply voltage of 10V
Output Configuration Current sinking NPN open collector transistor
Output Rating 3-wire hookup sinks 15 mA maximum, continuous
2-wire hookup sinks ≤10 mA (OFF-state) and ≥20 mA (ON state)
Output Protection Circuitry Protected against false pulse on power-up and short circuit of output
Output Response Time 4 milliseconds ON and OFF, except for opposed mode receivers, which are 8 ms ON, 4 ms OFF;
independent signal strength
(NOTE: 100 millisecond delay on power-up: output is non-conducting during this time)
Repeatability Opposed: 1.0 millisecond; Retro, Diffuse, Convergent, Plastic and Glass Fiber Optic: 1.3 milliseconds
Adjustments LIGHT/DARK OPERATE select switch on rear of sensor
Sensitivity control on rear of sensor allows precise gain setting (turn clockwise to increase gain)
Indicators Exclusive, patented Alignment Indicating Device (AID™, US patent #4356393) lights at top mounted red
LED indicator whenever the sensor sees a “light” condition, with a superimposed pulse rate proportional
to the light signal strength (the stronger the signal, the faster the pulse rate).
Construction Reinforced thermoplastic polyester housing, totally encapsulated, molded acrylic lenses, stainless steel
hardware
Environmental Rating Meets NEMA standards 1, 2, 3, 3S, 4, 4X, 12 and 13; IEC IP66
Connections Supplied with 3-pin quick-disconnect (QD) fitting and requires the use of mating cable model SMICC-312. Cable is
not supplied with sensors. See page 368 and Accessories section.
Operating Conditions Temperature: -20° to +70°C (-4 to +158°F)
Relative relative humidity: 90% at 50°C (non-condensing)
