potentiometer Adjustable-field models: five-turn adjustment screw sets cutoff distance between 20 and 100 mm (adjustable-field) or 30 and 150 mm (laser adjustable-field), clutched at both ends of travel IndicatorsLaser Emitter models: Green LED: Power applied All other models, 2
Led indicators: Green ON steady: Power ON Green flashing: Output overloaded Yellow
† ON steady: Light sensed Yellow
† flashing: Marginal excess gain (1.0 to 1.5x excess gain) in the light condition
† NOTE: Prior to date code 0223, the output indicator was red instead of yellow.Construction ABS housing, rated IEC IP67; NEMA 6; acrylic lens cover (Laser Emitter models have PMMA window)2.5 mm (adjustable-field only) and 3 mm mounting hardware included Connections 2 m or 9 m 4-wire PVC cable, or 4-pin 150 mm pigtail Pico-style QD ( Q ), or 4-pin 150 mm pigtail Euro-style QD ( Q5 ), or 4-pin Integral Pico-style QD ( Q7 ), or 4-pin Integral Euro-style QD ( Q8 ), depending on model.

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. More information online at
