Laser Contrast Sensor for Label Detection
Minneapolis-based Banner Engineering released its new Q3X laser contrast sensor, now available with fixed background suppression.
Featuring contrast detection and fixed background suppression, the Q3X LD50 reliably detects targets within the desired sensing range while ignoring objects in the background. A typical application is label detection on a bottle where contrast differences between the label and bottle provide reliable detection, but the sensor must ignore the shiny metal rail in the background. The shiny metal background could cause a false trigger for standard diffuse-mode sensors.
Out of the box, the Q3X LD50 operates like a fixed-field laser sensor and detects targets within its 50 mm sensing range. However, the sensor can be programmed for low-contrast sensing within this range, while ignoring objects at least 60 mm away. This allows the sensor to accurately detect its target without background objects affecting its performance.
Featuring high-speed part detection as fast as 250 μs, Banner’s Q3X laser contrast sensor can capture up to 2,000 events per second.
The Q3X is designed with a unique angled, 3-digit display of signal intensity, which provides high visibility of operating conditions from multiple angles. For an intuitive user setup, the Q3X has two tactile buttons conveniently located below the display.
The robust nickel-plated zinc die cast housing ensures reliable performance even in environments with exposure to cutting fluids and oils. Sensors are also rated to IP67, IP68 and IP69K for enhanced protection to water submergence and high-pressure washdown.
