SICK WTB9-3P2411 Background Suppression Photoelectric Sensor is a high-precision block sensor designed for industrial automation applications. It offers a detection range of 20 mm to 500 mm, making it suitable for detecting small objects and features even through difficult backgrounds.
The sensor utilizes an infrared light source combined with advanced background suppression technology to prevent false readings from surrounding surfaces. Its rugged VISTAL™ plastic housing is rated for IP66, IP67, and IP69K ingress protection to withstand harsh industrial environments. Operating temperature ranges from -40°C to 60°C ensure performance in extreme conditions.
This device operates on a maximum DC voltage of 30 V and supports a maximum current of 100 mA with a fast response time of 500 microseconds. The output is configured as PNP, enabling simple integration into automation systems via its 4-pin M12 connector terminal.
The sensor's CE and UL certifications validate its safety and reliability in various industrial settings. It is ideal for tasks such as detection of the smallest workpieces, checking for misalignment, and detecting transparent or shiny objects where traditional sensors may fail.
Installation is facilitated by versatile mounting options and cable connections including M8 and M12 male connectors. The W9 series integrates SIRIC® technology to suppress electromagnetic interference, reducing machine downtime and increasing process stability.
The sensor's block style offers precise background suppression detection. PNP output type provides durable and reliable signal transmission. Four-pin connector interface ensures stable electrical connections. Infrared LEDs deliver consistent and accurate detection performance.
Highly resistant plastic housing with comprehensive ingress protection ratings. Wide operating temperature range suitable for various climates. Compliance with CE and UL standards for industrial use.
This Photoelectric Sensor is extensively used in manufacturing, automation, and quality control environments where accurate object detection is critical. Its robust construction and advanced technology make it a dependable choice for industrial engineers and system integrators.
