Information About NT8-16412
The NT8-16412 is part of SICK’s NT8 series of contrast sensors developed for high-speed and high-precision detection tasks. It uses white light optics to reliably distinguish fine contrast differences on printed materials, labels, and markings at close range. The rugged zinc die-cast metal housing provides strong mechanical resistance and protection against dust and moisture in demanding industrial environments. With a fast 10 kHz switching frequency and IP67 protection, the sensor supports stable operation in applications with rapid material movement.
Key Features
- High-Speed Switching Performance: Supports switching frequencies up to 10 kHz, enabling accurate detection in fast-moving production and printing processes.
- White Light Optical System: Provides reliable contrast recognition across a wide range of colors and surface finishes.
- Short Sensing Distance Capability: Designed for precise detection at distances up to 9 mm, supporting fine registration and marking applications.
- Robust Metal Housing: Zinc die-cast construction ensures durability and long service life in mechanically demanding environments.
- Flexible Light Emission Direction: Exchangeable emission from the long or short side allows adaptable installation in confined machine spaces.
- NPN Output Configuration: Enables straightforward integration with standard industrial control and PLC systems.
- IP67 Environmental Protection: Ensures reliable operation in dusty, humid, or washdown-prone industrial settings.
The NT8-16412 delivers the reliability and precision required for high-speed contrast detection in industrial printing, packaging, and labeling systems.
