QS18VN6D: 61651 - Banner ABS Housing Photoelectric Sensor

The Banner QS18VN6D is a diffuse-type photoelectric sensor engineered to deliver accurate short-range detection with a sensing distance of up to 450 mm. This model operates using an infrared LED beam and outputs in NPN configuration through a 2-meter prewired cable. Its rectangular housing with an M18 mounting base is molded from high-strength ABS, balancing mechanical durability with a lightweight build suitable for space-constrained installations. The sensor is rated IP67 and conforms to NEMA 6 environmental standards, enabling consistent operation in dusty, humid, or washdown zones. Its power supply range of 10–30 V DC ensures compatibility with most PLC systems, and a built-in potentiometer simplifies the sensitivity adjustment process during installation. Performance is optimized with a repeatability of 150 µs and an output response time of just 0.6 ms, supporting fast-paced automation environments. Other highlights include an acrylic lens for optical clarity, a 4-pin interface, and intuitive LED indicators that offer real-time visual feedback for alignment and sensor status. These technical advantages make the QS18VN6D a highly dependable solution across diverse factory conditions.

Applications of QS18VN6D: 61651 - Banner

The QS18VN6D is ideally suited for short-range presence detection tasks where precision and speed are essential. In automated packaging units, it can detect product presence on a conveyor or trigger downstream processes such as sorting or labeling. In machine tool setups, it helps confirm part placement before drilling or pressing. Its fast response time allows integration with pick-and-place robots, particularly in electronic assembly or pharmaceuticals, where timing is critical. Its robust construction and diffuse sensing mode make it perfect for applications where reflective surfaces or unpredictable object shapes must be detected without the need for reflectors or receivers. From warehouse carton detection to small component sensing in compact OEM machinery, the QS18VN6D adapts easily. Thanks to its adjustable sensitivity and long operational life, this Banner photoelectric sensor is trusted by engineers looking for hassle-free installation, stable detection, and minimal maintenance over time.
