Overview
The Banner QS18VP6WQ is a miniature all-purpose photoelectric sensor from Banner Engineering’s WORLD-BEAM QS18 series. This divergent diffuse sensor offers a 100mm range, operates on 10-30V DC input, and provides complementary solid-state PNP output. The universal 18mm threaded barrel housing design makes it an ideal replacement for hundreds of other sensor styles. The sensor is equipped with a 150mm (6 in) M8 pigtail quick-disconnect connector.
Key Features
- Miniature self-contained photoelectric sensor in a universal housing that easily fits or retrofits almost any mounting situation
- 10V DC to 30V DC operation with complementary (SPDT) PNP outputs
- 100mm (3.9 inch) sensing range for compact material detection
- Infrared LED for reliable detection in varied ambient light conditions
- M8 pigtail connector for fast installation and removal
- IP67/NEMA 6 rated for washdown and humid environments
