QS186LE212Q8: 74317 - Banner M12 Laser Emitter Photoelectric Sensor

The QS186LE212Q8 sensor stands out for its long-range detection capabilities and rugged build quality. Operating in Laser Emitter mode, it uses a Visible Red Laser with a wavelength of 650 nm to provide consistent and pinpoint accuracy across distances up to 15 meters. Its compact rectangular housing with an M18 mount is made of durable ABS material, ensuring mechanical stability and protection against industrial stress. Certified with an IP67 ingress rating and NEMA 6 classification, this sensor can be confidently deployed in wet, dusty, or high-vibration environments without risk of performance degradation. Despite its powerful range, the QS186LE212Q8 operates efficiently on a standard 10–30 V DC power supply and uses a 4-pin M12 connector for quick integration. It features a rapid 10 ms power-up delay, LED status indicators for real-time diagnostics, and a precision PMMA lens that ensures stable laser emission. While it does not produce an output signal itself—serving purely as the emitter in a through-beam setup—it delivers unmatched performance when paired with a compatible receiver. The barrel diameter of 18 mm allows easy installation into standard industrial mounts, and its robust construction ensures minimal maintenance over years of service. Every detail of the QS186LE212Q8 reflects Banner’s commitment to high-performance optical sensing in demanding factory conditions.

Applications of Banner QS186LE212Q8

The Banner QS186LE212Q8 M12 Laser Emitter Photoelectric Sensor is ideally suited for long-distance object detection in automated material handling and warehouse conveyor systems. It is widely used in packaging plants to track product movement across extended distances and in automotive assembly lines where accuracy and reliability are critical. Since this sensor is designed as an emitter in a through-beam system, it works best when paired with a compatible laser receiver to detect fast-moving or low-reflectivity objects such as dark plastic, rubber, or matte-finished metals. Maintenance engineers appreciate the ease of installation and reliability of the QS186LE212Q8, especially in harsh areas where water spray or oil mist would typically affect standard sensors. Engineering students and technicians use it to understand the fundamentals of laser sensing and alignment in real-world automation scenarios. Whether you're setting up a new production line or upgrading legacy detection systems, this laser emitter delivers precise targeting and long-term value in challenging industrial conditions.
