The QL56 Series Luminescence Sensor is an easy-to-use, extremely sensitive luminescence sensor that emits ultraviolet (UV) light from high-power LEDs and detects visible light created by luminescent targets. This technology allows for the detection of luminescent marks (even invisible ones) on any surface, independently from its material, color, or distance inside the operating range, as long as the target radiates visible light when illuminated with UV light.

• Senses luminescent marks, even on luminescent backgrounds and irregular reflective surfaces
• High-power UV emission and a line of structured light provide a uniform and consistent beam for improved sensitivity
• Fast switching frequency and response time
• Push button programming for easy setup and clear bargraph indicator
• Choice of operating distance depending on model
• Durable, compact aluminum housing
• Bipolar (1 NPN & 1 PNP) output, plus 0.75 to 5.5V dc analog output
• 5-position swivel QD connector
