Overview
The Banner QS18VP6LPW-78992 is a polarized retro-reflective photoelectric sensor from Banner Engineering’s WORLD-BEAM QS18 series. Designed for industrial automation, motion control, and material handling applications, this all-purpose sensor combines proven reliability with universal M18 threaded mounting, making it a straightforward replacement for hundreds of legacy sensor models.
Key Features
- Polarized Retro-Reflective Mode: Uses visible red light (650 nm) for reliable target detection with minimal wiring complexity
- Dual-Output Configuration: PNP transistor output with complementary NO/NC channels supports both Light-ON and Dark-ON operation
- Extended Sensing Range: 3.5 m operating range handles moderate to large part detection across conveyors and assembly stations
- Industrial Enclosure: IP67 / NEMA 6 rated housing with thermoplastic body and acrylic lens resists moisture, dust, and light oils
- Pre-Wired Cable: Includes 6.5 ft (2 m) cable with bare-end flying leads for rapid field termination
- Potentiometer Adjustment: Built-in sensitivity tuning for fine-tuning detection thresholds on the job
