Overview
The Banner QS186LEQ5-71501 is a compact yet robust laser photoelectric sensor from Banner Engineering’s WORLD-BEAM QS18 series. This Laser Class 1 sensor features through-beam opposed mode operation, ideal for applications requiring long-range object detection in industrial automation environments. With a 15-meter sensing range and 10-30 VDC supply voltage, it delivers consistent, reliable performance across manufacturing, packaging, and logistics applications. The sensor comes pre-wired with a 6-inch M12 pigtail connector for quick integration into control systems.
