Overview
The Banner QS18VN6DBQ-73054 is an infrared diffuse photoelectric sensor from Banner Engineering’s WORLD-BEAM QS18 series. This all-purpose sensor provides dependable object detection across a wide range of industrial automation, packaging, and material handling applications. With its compact 18 mm threaded barrel design, universal mounting, and proven sensing capability, the QS18VN6DBQ-73054 serves as an ideal replacement for many older sensor models while maintaining drop-in compatibility with QS18 installations.
Key Features
- Diffuse detection mode with 450 mm sensing range for reliable object identification
- Infrared (IR) light source for stable performance across varying ambient light conditions
- NPN transistor output with complementary NO/NC switching (Light-ON or Dark-ON operation)
- Potentiometer-adjustable sensitivity for application-specific tuning
- 4-pin Pico-style M8 connector for quick connect/disconnect wiring
- IP67 / NEMA 6 sealed thermoplastic housing with acrylic lens for protection in wet and dusty environments
- Wide operating temperature range (-20 to +70°C) suitable for most industrial settings
Technical Specifications
The QS18VN6DBQ-73054 meets standard industrial sensor specifications and is suitable for integration into control systems operating at 10–30 Vdc nominal 12/24 Vdc supply voltage. Sensor output is rated for direct PLC input with complementary solid-state switching. The unit’s compact form factor and standard M18 threaded mount enable retrofitting into existing sensor housings.
