MINI-BEAM Expert Series


  • 10 to 30V dc supply voltage with bipolar NPN/PNP outputs
  • Easy push-button TEACH-mode setup
  • Available in polarized retroreflective, polarized retroreflective clear object, convergent, diffuse and divergent diffuse, and glass or plastic fiber optic sensing modes
  • Convergent and fiber optic models with infrared or visible red, blue, green or white LED light source, depending on application
  • Polarized retroreflective models for clear object detection
  • 18 mm threaded barrel or side mounting options

Product Specifications

Supply Voltage and Current10 to 30V dc (10% max. ripple) @ less than 45 mA (exclusive of load)
RangePolarized Retroreflective:10 mm to 3 m, range is specified using one model BRT-3 retroreflector
Polarized Retroreflective (clear object):1 m, range is specified using one model BRT-2X2 retroreflector
Diffuse (long range):1100 mm
Diffuse (short range):380 mm
Divergent Diffuse:130 mm
Convergent:16 or 43 mm, depending on model
Plastic and Glass Fiber Optic:Range varies by sensing mode and fiber optics used
Supply Protection CircuitryProtected against reverse polarity and transient voltages
Output ConfigurationBipolar:One NPN (current sinking) and one PNP (current sourcing); configuration in TEACH sequence for light operate (LO) or dark operate (DO)
Output Rating150 mA max. each output @ 25° C, derated to 100 mA @ 70° C (derate approximately 1 mA per ° C) OFF-state leakage current:less than 5 µA @ 30V dc
Output saturation voltage:
PNP:less than 1V @ 10 mA and less than 2V @ 150 mA
NPN:less than 200 mV @ 10 mA and less than 1V @ 150 mA
Output Protection CircuitryProtected against false pulse on power-up and continuous overload or short circuit of outputs
Output Response TimeResponse time is independent of signal strength. Sensors will respond to either a light or dark signal of 500 microsecond or longer duration, 1 kHz max.
Delay at Power-up1 second; outputs do not conduct during this time.
Repeatability100 microseconds
AdjustmentsPush-button TEACH-mode sensitivity setting; remote TEACH-mode input is provided (gray wire)
Indicators2 LED Indicators:Yellow and bicolor Green/Red
Green (RUN Mode):ON when power is applied, flashes when received light level approaches the switching threshold
Red (TEACH Mode):OFF when no signal is received, pulses to indicate signal strength (received light level). Rate is proportional to signal strength (the stronger the signal, the faster the pulse rate). This is a function of Banner's Alignment Indicating Device (AID).
Yellow (TEACH Mode):ON to indicate sensor ready to learn output ON condition; OFF to indicate sensor is ready to learn output OFF condition
Yellow (RUN Mode):ON when outputs are conducting
ConstructionReinforced thermoplastic polyester housing, totally encapsulated, o-ring seal, acrylic lenses and stainless-steel screw
Environmental RatingNEMA 1, 2, 3, 3S, 4, 4X, 6, 12 and 13; IP67
ConnectionsPVC-jacketed 5-conductor 2 m or 9 m cables, or 5-pin Euro-style QD. QD cable are ordered separately.
Operating ConditionsTemperature:-20° to +70° C
Relative humidity:90% @ 50° C (non-condensing)
Application NoteThe first condition presented during TEACH mode becomes the output ON condition.
