The QL50 Series Sensor is an easy-to-use, compact luminescence sensor that emits ultraviolet light from an LED and scans for luminescence in materials. The QL50 senses luminescence that is inherent in a material, or it can sense luminophores that have been added to a material in process to make it luminescent.

• Detects luminescence inherent in a material and luminophores added to a material
• Senses luminescent marks, even on luminescent backgrounds and reflective surfaces such as ceramic, metal or mirrored glass
• Features compact, self-contained design
• Offers easy-to-set programming options for sensing precision
• Responds in 250 microseconds
• Available in models with NPN or PNP discrete outputs
