Q45 Laser DC Series


  • Available in Class 2 polarized and non-polarized retroreflective sensing modes
  • Visible laser beam for ease of alignment and long-range sensing
  • Narrow effective beam for precision small object or edge detection
  • 10 to 30V dc supply voltage with bipolar NPN/PNP outputs
  • Ranges up to 70 m
  • 30 mm threaded mounting base

Product Specifications

Supply Voltage and Current10 to 30V dc (10% max. ripple) @ less than 50 mA (exclusive of load)
RangeNon-polarized Retroreflective:0.3 to 70 m, range is specified using one model BRT-2X2 retroreflector
Polarized Retroreflective:0.6 to 40 m, range is specified using one model BRT-2X2 retroreflector
Supply Protection CircuitryProtected against reverse polarity and transient voltages
Output ConfigurationBipolar:One NPN (current sinking) and one PNP (current sourcing); light operate (LO) or dark operate (DO) selectable
Output Rating250 mA max. each output up to 50° C, derated to 150 mA @ 70° C (derate 5 mA per ° C) OFF-state leakage current:less than 1 µA
Output saturation voltage:less than 1V @ 10 mA and less than 2V @ 250 mA
Output Protection CircuitryProtected against false pulse on power-up and continuous overload or short circuit of outputs
Output Response Time2 milliseconds ON/OFF; response time is independent of signal strength.
Delay at Power-up100 milliseconds; outputs do not conduct during this time.
Repeatability0.5 milliseconds; repeatability is independent of signal strength.
AdjustmentsLight-operate/dark-operate select switch and multi-turn sensitivity control on top of sensor, beneath a transparent polycarbonate o-ring sealed cover, allows precise sensitivity setting (turn clockwise to increase gain). Optional logic and logic/display modules have adjustable timing functions.
IndicatorsIndicator LEDs are highly visible, located beneath a raised transparent polycarbonate dome on top of the sensor. Power (Green):LED lights whenever 10 to 30V dc power is applied and flashes to indicate ouput overload or output short circuit
Signal (Red):LED lights whenever the sensor sees its modulated light source and pulses at a rate proportional to the strength of the received light signal
Load (Yellow):LED lights whenever an output is conducting
Optional 7-segment display:LED display lights for signal strength
ConstructionMolded reinforced thermoplastic polyester housing, o-ring sealed transparent polycarbonate cover, molded acrylic lenses and stainless-steel hardware. Q45s are designed to meet 1200 psi washdown. The base of cabled models has a 1/2 inch NPS integral internal conduit thread.
Environmental RatingNEMA 6P; IEC IP67
Laser ClassificationClass 2 laser product. US Safety Standards 21 CFR 1040.10 and 1040.11; European Standards EN 60825 and IEC 60825
ConnectionsPVC-jacketed 5-conductor 2 m or 9 m cables, or 5-pin integral Euro-style QD (Q6), or 5-pin integral Mini-style QD (Q), depending on model. QD cable are ordered separately.
Operating ConditionsTemperature:-40° to +70° C
Relative humidity:90% @ 50° C (non-condensing)
Application NoteOptional logic timing modules are available.
