Engineered for demanding industrial automation, the Keyence Digital Laser Sensor series LV-N11N, LV-N12N, LV-N11CN, LV-N12CN, and LV-N11MN delivers unparalleled precision and speed in a compact form factor. These NPN output sensors excel in high-speed object detection, offering response times as low as 80 microseconds in HIGH SPEED mode. Whether you need dual outputs for independent control (LV-N11N), a single output for simple tasks (LV-N11CN), or a monitor output for analog feedback (LV-N11MN), this series provides a tailored solution. The robust design supports up to 17 expansion units, ensuring scalability for complex systems. Built with reverse polarity protection and over-current protection, these sensors guarantee reliable performance in harsh environments.
