Q45 Series
Fullsize Sensors
PHOTOELECTRICS Lasers that emit visible radiation in the wavelength range from 400 to 700 nm where eye protection is normally afforded by aversion responses, including the blink reflex. This reaction may be expected to provide adequate protection under reasonably foreseeable conditions of operation, including the use of optical instruments for intrabeam viewing. Reference 60825-1 Amend. 2 © IEC:2001(E), section 8.2.
For safe laser use:
• Do not permit a person to stare at the laser from within the beam.
• Do not point the laser at a person’s eye at close range.
• Locate open laser beam paths either above or below eye level, where practical.
Q45 AC Specifications
Supply Voltage and Current 90 to 250V ac (50 - 60 Hz). Average current 20 mA. Peak current 500 mA at 120V ac, 750 mA at 250V ac. Supply Protection Circuitry Protected against transient voltages Output ConfigurationQ45VR2 models: SPDT (single-pole double-throw) electromechanical relay output (except emitters) Q45BW22 models: Short circuit/overload protected FET solid-state relay Output RatingQ45VR2 models: Max. switching power (resistive load): 150W, 600 VA Max. switching voltage (resistive load): 250V ac or 30V dc Max. switching current (resistive load): 5A @ 250V ac Min. voltage and current: 5V dc, 0.1 mA Mechanical life of relay: 10,000,000 operations Electrical life of relay at full resistive load: 100,000 operations Q45BW22 models:Continuous current: 300 mA max. to 50° C (derate to 200 mA at 70° C, 5 mA/° C) Inrush current: 3A max. for 100 milliseconds, 5A max. for 1 millisecond Off-state leakage current: less than 100 mA Saturation voltage: less than 3V at 200 mA Output Protection CircuitryQ45VR2 models: Protected against false pulse on power-up Q45BW22 models: Manually-resettable output latch-out
trips in the event of an output overload or short circuit condition. The green Power LED flashes to indicate the latch-out. To reset the output, remove power to the sensor and load for 5 seconds, then restore power. Output Response TimeQ45VR2 models: 15 milliseconds ON/OFF 2 milliseconds ON, 1 millisecond OFF Q45BW22 models:
Opposed mode: All other sensing modes: 2 milliseconds ON/OFF(NOTE: 100 millisecond delay on power-up. Output does not conduct during this time.) RepeatabilityOpposed mode: 0.25 milliseconds; All sensing modes: 0.5 millisecondsResponse time and repeatability specifications are independent of signal strength. Indicators AdjustmentsBeneath sensor’s transparent cover: Indicator LEDs are highly visible, located beneath a raised transparent polycarbonate dome on top of the sensor. Light Operate (LO), Dark Operate (DO) 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. Power (green) LED lights whenever 90-250V ac power is applied, and flashes to indicate output 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 relay is energized Optional 7-element LED signal strength display module
