Overview
The Banner QS18VN6LPQ8 is a WORLD-BEAM series photoelectric sensor designed for all-purpose industrial detection. This polarized retro-reflective sensor delivers a 3.5 meter sensing range and operates on 10–30 VDC input, making it compatible with standard industrial control voltages (12 VDC / 24 VDC nominal). The integral M12 4-pin connector and molded QD (quick-disconnect) configuration simplify installation in tight spaces. Red light optics and potentiometer adjustment allow for field-tuned sensitivity in production environments.
Key Features
- WORLD-BEAM Polarized Retro-Reflective Design: Robust performance against ambient light interference and background reflections.
- 3.5 Meter Sensing Range: Suitable for conveyor, packaging, and material handling detection tasks.
- M12 Quick-Disconnect Connector: Integral 4-pin Euro-style M12 QD connector for fast field replacement and reduced downtime.
- Complementary Solid-State NPN Output: Programmable Light-ON or Dark-ON operation with NO/NC digital outputs.
- IP67 / NEMA 6 Rated Housing: Thermoplastic body with acrylic lens; rated for –20 to +70°C ambient operation.
- Potentiometer Adjustment: Fine-tune sensitivity without special tools or software.
