Information About WT18-3P420
The WT18-3P420 is part of the SICK W18-3 series, engineered for reliable object detection in demanding industrial automation applications. This sensor uses background suppression technology to accurately detect targets while ignoring reflective backgrounds beyond the set sensing distance. Its infrared LED light source at 870 nm supports stable performance across a wide range of materials and surface finishes. The compact rectangular housing and IP67 protection rating allow installation in harsh environments exposed to dust, moisture, and temperature variations.
Key Features
- Background Suppression Technology: Enables precise detection of objects while reliably ignoring backgrounds located beyond the defined sensing distance.
- Wide 10–1000 MM Detection Range: Supports flexible use across short and long sensing distances within a single device.
- PNP Output With NO/NC Selection: Allows versatile signal configuration for integration with industrial control systems.
- Fast 700 µs Response Time: Ensures accurate switching performance in high-speed automation and material handling processes.
- Infrared LED Light Source: Provides stable illumination and consistent detection across varying object colors and textures.
- Fine Sensitivity Adjustment: Uses a 4-turn potentiometer for precise tuning of the detection threshold.
- IP67-Rated ABS Housing: Protects the sensor from dust and water ingress in demanding industrial environments.
The WT18-3P420 delivers the reliability and precision required for consistent object detection in automated industrial systems.
