Output Protection CircuitryProtected against false pulse on power-up
Output Response TimeResponse time is independent of signal strength. Q45VR3 models:15 milliseconds ON/OFF
Q45BW13 models:
Opposed:2 milliseconds ON; 1 milliseconds OFF
All others:2 milliseconds ON/OFF
Delay at Power-upQ45VR3 models:100 milliseconds; relay is de-energized during this time.
Q45BW13 models:100 milliseconds; outputs do not conduct during this time.
RepeatabilityRepeatability is independent of signal strength. Opposed:0.25 milliseconds
All others:0.5 milliseconds
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 24 to 250V ac, or 12 to 250V dc power is applied
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 relay is energized
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
ConnectionsQ45VR3 models:PVC-jacketed 2 m or 9 m cables, or 5-pin integral Mini-style QD (Q). QD cable are ordered separately.
Q45BW13 models:PVC-jacketed 2 m or 9 m cables, or 4-pin integral Mini-style QD (Q), depending on model. QD cable are ordered separately.
Operating ConditionsTemperature:-25° to +55° C
Relative humidity:90% @ 50° C (non-condensing)
Application NoteTransient suppression is recommended for contacts switching inductive loads. Optional logic timing modules are available.
