Supply Voltage and Current 10 to 30V dc (10% maximum ripple) at less than 25 mA (exclusive of load)
Supply Protection Circuitry Protected against reverse polarity and transient voltages
Output Configuration Bipolar: One current sourcing (PNP) and one current sinking (NPN) open-collector transistor
Output Rating 150mA maximum each output at 25°C, derated to 100mA at 70°C (derate ≈1mA per °C)
Off-state leakage current less than 1 microamp
Output saturation voltage (PNP output) less than 1 volt at 10mA and less than 2 volts at 150mA
Output saturation voltage (NPN output) less than 200 millivolts at 10mA and less than 1 volt at 150mA
Output Protection Circuitry Protected against false pulse on power-up and continuous overload or short-circuit of outputs
Output Response Time Sensors will respond to either a "light" or a "dark" signal of 1 millisecond or longer duration, 500Hz max.
0.3 millisecond response modification is available. See note on page 1.
(NOTE: 100 millisecond delay on power-up: outputs do not conduct during this time.)
Repeatability 0.3 milliseconds. Response time and repeatability specifications are independent of signal strength.
Adjustments Light/Dark Operate select switch, and 15-turn slotted brass screw Gain (sensitivity) adjustment potenti-
ometer (clutched at both ends of travel). Both controls are located on rear panel of sensor and protected
by a gasketed, clear acrylic cover.
Indicators Exclusive, patented Alignment Indicating Device system (AID
™
, US patent #4356393) lights a rear-panel
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, o-ring sealing, acrylic lenses, and
stainless steel screws.
Environmental Rating Meets NEMA standards 1, 2, 3, 3S, 4, 4X, 12, and 13; IEC IP66
Connections PVC-jacketed 4-conductor 2 m (6.5') or 9 m (30') cables, or 4-pin Euro-style quick disconnect (QD) fitting
are available. QD cables are ordered separately. See page 6.
Operating Conditions Temperature: -20 to +70°C (-4 to +158°F)
Maximum relative humidity: 90% at 50°C (non-condensing)
Application Notes The NPN (current sinking) output of dc MINI-BEAM sensors is directly compatible as an input to Banner
logic modules, including all non-amplified MAXI-AMP and MICRO-AMP modules. MINI-BEAMs are
TTL compatible.

“AID” Indicator LED Lights when the
sensor sees its own modulated
light and pulses at a rate proportional to the
strength of the received light signal.
*Note: Turn Light/Dark Operate switch fully clockwise
to the end stop for light-operated output and
fully counter-clockwise to the end stop for
dark-operated output.
