QS18VP6AF250Q8: 802446 - Banner Adjustable Photoelectric Sensor

The QS18VP6AF250Q8 by Banner is a compact and rugged Photoelectric Sensor built to deliver reliable detection in challenging industrial conditions. Its adjustable background suppression mode allows precise object detection at a distance of up to 250 mm, even in the presence of reflective or complex backgrounds. The device uses a visible red LED beam operating at 640 nm, and features a potentiometer adjustment for fine-tuning the sensing range based on the application requirement. Housed in a rectangular ABS enclosure with M18 mounting, the sensor is designed for fast and secure installation. It is rated IP67 and NEMA 4X, providing resistance against water ingress, dust, and industrial contaminants. With PNP output and discrete I/O, the sensor integrates easily into existing control systems using its M12 connector and 4-pin interface. It supports a power supply of 10–30 V DC and delivers a fast response time of 2.8 ms, with a repeatability of 130 µs and a 200 ms power-up delay. Additional features include a durable acrylic lens, an 18 mm barrel diameter, and clear LED status indicators for on-site visibility. With a wide operating temperature range from -40°C to 60°C, this sensor ensures stable detection across diverse operating environments.

Applications of Banner QS18VP6AF250Q8

The Banner QS18VP6AF250Q8 Adjustable Photoelectric Sensor is ideal for automation tasks that require precise detection of objects against unpredictable or reflective backgrounds. It is commonly used in conveyor systems to detect packages of varying sizes and materials, packaging lines for presence verification of bottles, cartons, and pouches, and assembly stations where consistent part detection is critical. Its adjustable sensing capabilities make it well-suited for detecting dark, shiny, or multicolored objects without being affected by background interference. In robotics and pick-and-place systems, it ensures that items are accurately sensed before triggering actuation. Maintenance engineers appreciate its fast installation, minimal false triggers, and adjustable flexibility, while students and industrial trainees use this model to learn background suppression techniques in modern automation labs. Whether you’re upgrading legacy sensors or installing new automation lines, the QS18VP6AF250Q8 delivers accuracy, durability, and ease of integration.
