The QS18EP6LPQ8: 71987 sensor from Banner offers powerful features tailored for harsh factory environments. It uses a visible red LED beam (630 nm) with a polarized sensing mode to effectively detect objects up to 3500 mm away, reducing false detections from shiny surfaces. Built with a rectangular ABS housing and M18 mount, the sensor provides both durability and ease of installation. The IP67 and NEMA 4X ratings ensure protection from dust, water, and high humidity (up to 95% @ 50Β°C), making it suitable for demanding applications like packaging, bottling, and automotive assembly. The sensor features a 4-pin M12 connector for quick setup and supports PNP output with a fast 0.6 ms response time. Operating on 10β30 V DC and functioning reliably in a wide temperature range of -20Β°C to +70Β°C, it also includes a Teach Button for easy configuration on-site. Other highlights include a repeatability of 75 Β΅s, a startup delay of 100 ms, and LED indicators for real-time status. With a PMMA lens and a compact barrel diameter of 18 mm, this model is engineered for precision, durability, and simplicityβtrusted by engineers in both new installations and maintenance retrofits.
Applications of QS18EP6LPQ8: 71987 - Banner Polarized Retroreflective Sensor
This Banner Photoelectric Sensor is commonly used in conveyor systems, packaging lines, and assembly machines where non-contact object detection is critical. Thanks to its polarized detection, it minimizes errors when identifying glossy or transparent objects, making it highly useful in bottle filling plants, carton detection, and shrink-wrapping stations. Maintenance engineers prefer this sensor for its plug-and-play M12 connection and ease of reconfiguration using the built-in Teach Buttonβespecially useful during equipment upgrades or product line changes. Whether itβs for automated part detection on production conveyors or quality inspection lines in FMCG plants, the QS18EP6LPQ8 helps eliminate false positives and ensures smooth material flow. Its rugged build, long sensing distance, and fast response make it a trusted choice in fast-paced industrial environments where reliability and uptime are critical.
