The Q3XTBLD50-Q8 Banner 50 mm Background Suppression Sensor from Banner is part of the Q3X Series used in industrial automation. The Q3XTBLD50-Q8 provides a 0–50 mm sensing range with fixed background suppression at 60 mm and a 0.25 ms response time for high-speed detection. It operates with a 655 nm Class 2 laser and includes bipolar NPN and PNP outputs. With IP67, IP68, and IP69K ratings, it supports washdown and oil-exposed environments.
In conveyor systems, packaging lines, and assembly machines, the Q3XTBLD50-Q8 is used for detecting small contrast differences such as label edges or dark parts against reflective backgrounds. Fixed background suppression helps ignore objects beyond the target zone, ensuring stable output signals. The 5-pin M12 quick-disconnect simplifies electrical installation, while the M18 mount and nickel-plated zinc housing provide secure mechanical integration in industrial equipment.
The Q3XTBLD50-Q8 within the Q3X Series strengthens Banner’s structured sensing portfolio for short-range contrast detection. With 50 mm range, 0.25 ms response, bipolar outputs, and IP69K protection, the Q3XTBLD50-Q8 Banner 50 mm Background Suppression Sensor supports consistent and reliable operation in demanding industrial automation applications across India.
