MINI-BEAM Namur DC Series


MINI-BEAM sensors for hazardous environments with approved switching amplifiers with intrinsically safe input circuits

  • 5 to 15V dc supply voltage with a constant current output of 1 mA or less in the dark and 2 mA or less in the light condition
  • Intrinsically safe sensors with MINI-BEAM performance and small size
  • Available in opposed, polarized and non-polarized retroreflective, convergent, diffuse and divergent diffuse, and glass fiber optic sensing modes
  • For use with approved switching amplifiers with intrinsically safe input circuits
  • 18 mm threaded barrel or side mounting options

Product Specifications

Supply Voltage 5 to 15V dc (provided by the amplifier to which the sensor is connected)
RangeOpposed:6 m
Non-polarized Retroreflective:5 m, range is specified using one model BRT-3 retroreflector
Polarized Retroreflective:50 mm to 2 m, range is specified using one model BRT-3 retroreflector
Diffuse:380 mm
Divergent Diffuse:75 mm
Convergent:16 or 43 mm, depending on model
Glass Fiber Optic:Range varies by sensing mode and fiber optics used
OutputConstant current output:1 mA or less in the dark condition and 2.1 mA or less in the light condition
Output Response TimeOpposed Receiver:2 milliseconds ON; 400 microseconds OFF
All others:5 milliseconds ON/OFF (does not include amplifier response)
Ajustments15-turn slotted brass screw sensitivity (Gain) adjustment potentiometer, clutched at both ends of travel; located on rear panel of sensor and protected by a gasketed, clear acrylic cover.
IndicatorsAlignment Indicating Device system (AID) 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).
ConstructionReinforced thermoplastic polyester housing, totally encapsulated, o-ring sealing, acrylic lenses and stainless-steel screws
Environmental RatingNEMA 1, 2, 3, 3S, 4, 4X, 6, 12 and 13; IEC IP67
ConnectionsPVC-jacketed 2-conductor 2 m or 9 m cables, or special 4-pin Euro-style QD. QD cable are ordered separately.
Operating ConditionsTemperature:-40° C to + 70° C
Relative humidity:90% @ 50° C (non-condensing)
