  • Intrinsically safe sensors with Q45 performance
  • Available in opposed, polarized and non-polarized retroreflective, convergent, diffuse, and glass or plastic fiber optic sensing modes
  • For use with approved switching amplifiers with intrinsically safe input circuits
  • 30 mm threaded mounting base

Product Specifications

Supply Voltage 5 to 15V dc (provided by the amplifier to which the sensor is connected)
RangeOpposed:6 m
Non-polarized Retroreflective:9 m, range is specified using one model BRT-3 retroreflector
Polarized Retroreflective:6 m, range is specified using one model BRT-3 retroreflector
Diffuse (short range):380 mm
Diffuse (long range):1 m
Convergent:38 or 100 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)
AjustmentsMulti-turn sensitivity control on top of sensor, beneath a transparent o-ring sealed Lexan cover, allows precise sensitivity setting (turn clockwise to increase gain).
IndicatorsIndicator LEDs are highly visible, located beneath a raised transparent Lexan dome on top of sensor. Emitters:
Power (Red):lights whenever 5-15V dc power is applied
All others:
Signal (Red):lights whenever the sensor sees its modulated light source
ConstructionMolded reinforced thermoplastic polyester housing, o-ring sealed transparent Lexan top 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
ConnectionsPVC-jacketed 2-conductor 2 m or 9 m cables, or 4-pin Euro-style QD. QD cable are ordered separately.
Operating ConditionsTemperature:-40° C to + 70° C
Relative humidity:90% @ 50° C (non-condensing)
