The Banner S18SN6L is a diffuse-mode photoelectric sensor featuring a 6-inch (approx. 150 mm) fixed sensing range and NPN output. Housed in an M18 plastic barrel, it emits an infrared beam for object detection and is built for use in tight industrial spaces. Its compact, reliable design makes it an ideal fit for automation, packaging, and OEM systems requiring consistent short-range sensing. Key Features: Infrared diffuse sensing with 6" (150 mm) range M18 threaded housing for standard mounting NPN (sinking) output Reliable sensing of opaque and matte surfaces Compact and cost-effective solution Bright LED indicators for power and output IP67 environmental protection rating Applications: Detection of parts in automated feeders Object sensing in packaging machines Short-range presence sensing in assembly systems General-purpose automation in OEM equipment
