Load
10-30V dc
The output type for all models is Bipolar NPN/PNP; load 150 mA max., each output.
Specifications
Supply Voltage and Current
10 to 30 V 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
150 mA maximum each output at 25 °C, derated to 100 mA at 70 °C
(derate ≈1 mA per °C)
Off-state leakage current: < 1 microamp
Output saturation voltage (PNP output): < 1 volt at 10 mA and < 2
volts at 150 mA
Output saturation voltage (NPN output): < 200 millivolts at 10 mA and
< 1 volt at 150 mA
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, 500 Hz max. 0.3 millisecond response
modification is available. See note below.
(100 millisecond delay on power-up; outputs do not conduct during this
time.)
To order dc MINI-BEAMs with 0.3 millisecond on/off response, add the
suffix “MHS” to the model numbers (e.g, SM31EMHS & SM31RMHS).
This modification reduces sensing range (and excess gain).
Adjustments
LIGHT/DARK OPERATE select switch, and 15-turn slotted brass screw
GAIN (sensitivity) adjustment potentiometer (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, 6, 12, and 13; IEC IP67
Connections
PVC-jacketed 4-conductor 2 m (6.5 ft) or 9 m (30 ft) cables, or 4-pin
Euro-style quick disconnect (QD) fitting are available. QD cables are
ordered separately.
Operating Temperature
Temperature: −20 °C to +70 °C (−4 °F 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.
