Supply Protection Circuitry
i) 9 m (30') cables are available by adding suffix “W/30” to the model number of any cabled sensor (e.g., SM312LP W/30).
ii) Standard models have 1 millisecond output response; models with 0.3 millisecond (300 microsecond) response are available by
iii) A 150 mm (6") long pigtail cable with attached QD connector is available by adding suffix “QDP” to the model number
iv) A model with a QD connector requires an optional mating cable (see accessories, page 8).
adding suffix “MHS” to the model number (e.g., SM312LPMHS). Note that this modification reduces the maximum operating
temperature to +50º C (122º F).
(e.g., SM312LPQDP).

10 to 30V dc (10% maximum ripple) at less than 25mA (exclusive of load)
Protected against reverse polarity and transient voltages
Bipolar: One current sourcing (PNP) and one current sinking (NPN) open-collector transistor
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
Protected against false pulse on power-up and continuous overload or short-circuit of outputs
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 below.
100 millisecond delay on power-up; outputs do not conduct during this time.
0.3 milliseconds. Response time and repeatability specifications are independent of signal strength.
LIGHT/DARK OPERATE select switch, and 15-turn slotted brass screw GAIN (sensitivity) adjustment po-
tentiometer (clutched at both ends of travel). Both controls are located on rear panel of sensor and
protected by a gasketed, clear acrylic cover.
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).
Reinforced PBT thermoplastic polyester housing, totally encapsulated, o-ring sealing, acrylic lenses, and
stainless steel screws.
Meets NEMA standards 1, 2, 3, 3S, 4, 4X, 6, 12, and 13; IEC IP67
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 8.
Temperature: -20° to +70° C (-4° to +158° F)
Maximum relative humidity: 90% at 50° C (non-condensing)
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.
