Luminescence Sensor is not fooled by color/contrast shifts.
Press Release Summary:
Microprocessor-controlled, self-contained QL Series utilizes modulated ultraviolet LED to scan for luminescence inherent in material or sense luminophores that have been added to material in process to make it luminescent. Series includes models QL50 and QL55, each of which offers push-button programming, 250 µsec response time, and 2 LEDs to indicate operating and output status. Active sensing range varies from 0-1.57 in. to 0.35-2.95 in., depending on model.

Advanced New Luminescence Sensors Can't Be Fooled By Color and Contrast Shifts
Minneapolis, MN-June 20, 2003-Banner Engineering Corp. has announced its new QL Series of powerful microprocessor-controlled luminescence sensors. Consisting of the QL50 and QL55, these self-contained sensors utilize a modulated ultraviolet LED to scan for luminescence in materials, and are not affected by color or contrast shifts that can challenge traditional optical sensors. The QL Series sensors detect 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. "Luminescence sensors are ideal for applications requiring the detection of color marks, clear adhesive labels, tamper-evident seals, oil or grease and fluorescent product markings where the background color may vary causing a contrast change that would confuse or fool other sensing methods," said Joe Dolinsky, Technical Manager for Banner's photoelectric products. "Our new QL50 and QL55 offer an effective sensing solution for these applications that prove too challenging for conventional photoelectric sensors. Their powerful microprocessor design provides accurate sensing at the high speeds found in automated production and they can differentiate luminescent marks on reflective surfaces such as ceramics, metal and mirrored glass," Dolinsky added.
Both models feature simple push-button programming. The QL50 may be programmed two ways. A Quick-SET mode where the sensor is taught to detect the specific luminescence intensity of a target and ignore the less-intense background, and a Fine-Detect mode that increases the unit's sensing precision to detect the specific luminescence intensity of a target and ignore all other surfaces with more or less luminescence.
The QL55 features a robust metal housing, enhanced sensitivity and two-step TEACH programming where the sensor is taught both the luminescent target and background conditions and automatically selects light operate or dark operate.
Both models feature a fast 250 microsecond response time and two bright LEDs to indicate operating and output status. The QL50 has an active sensing range of 0 mm to 40 mm (0" to 1.57") with maximum signal at 10 mm (0.39"). The QL55 features sensing ranges from 9 mm to 75 mm (0.35" to 2.95") depending on model. A compact housing size and 3-position rotating quick-disconnect cable add to the mounting flexibility of these sensors.
The QL50 offers NPN or PNP discrete outputs by model. The QL55 features switch-selectable NPN and PNP discrete outputs plus a 0 to 5.5V dc analog output and an output OFF-delay option that extends the duration of the sensor's output by 20 milliseconds. The QL50 begins at a breakthrough price of $389.00 and the QL55 begins at $895.00.
