Banner Engineering has announced that its Q3X laser contrast sensor is now available with fixed background suppression. Featuring contrast detection plus fixed background suppression, the Q3X LD50 detects targets within the desired sensing range while ignoring objects in the background.

Out of the box, the product 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, the laser contrast sensor can capture up to 2000 events per second.

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 a shiny metal rail in the background. The shiny metal background could cause a false trigger for standard diffuse-mode sensors.

The product is designed with an angled, three-digit display of signal intensity, which provides high visibility of operating conditions from multiple angles. For intuitive user set-up, the sensor has two tactile buttons located below the display.

The unit’s 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 immersion and high-pressure washdown.
