MINI-BEAM Sensors with Green LED
Green LED MINI-BEAM Product Specifications
Certifications
Supply Voltage and Current 10 to 30V dc (10% maximum ripple) at less than 25mA (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 are non-conducting during this time.)
Repeatability Opposed: 0.14 milliseconds; Non-Polarized and Polarized Retro, Diffuse, Convergent, Glass and Plastic
Fiber Optic: 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 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.
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 VALOX
®
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 ft) or 9 m (30 ft) cables, or 4-pin euro-style quick disconnect (QD)
fitting are available. QD cables are ordered separately. See page 6.
Operating Temperature 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.
