ICK WTB8-P2231 Background Suppression Photoelectric Sensor (Order Number: 6033209)<\/h1>\n
<\/div>\n

Product Overview<\/h2>\n
<\/div>\n
The SICK WTB8-P2231 is a miniature diffuse-mode photoelectric sensor with background suppression, part of SICK’s W8 series, engineered for reliable object detection in industrial automation. It leverages a visible red LED light source and background suppression technology to accurately identify objects while ignoring irrelevant background elements, making it suitable for applications like packaging lines, material handling, and assembly systems where stable detection of small or medium-sized objects is critical. The sensor features a compact rectangular ABS housing with an IP67 protection rating, allowing it to withstand dust, moisture, and temperature variations in harsh industrial settings. It is CE-certified and RoHS-compliant, with a stainless-steel mounting bracket for flexible installation, offering a cost-effective and durable solution for diverse industrial detection needsSICK.<\/div>\n
<\/div>\n

Main Functions<\/h2>\n
<\/div>\n
    \n
  1. Background-Suppressed Object Detection<\/strong>: Uses diffuse-mode sensing with background suppression to detect objects within 40 mm – 300 mm (for 90% diffuse reflectance white objects per DIN 5033), eliminating false triggers from background surfaces for consistent performanceSICK.<\/li>\n
  2. Adjustable Sensing Parameters<\/strong>: A 4-turn potentiometer enables precise adjustment of the sensing distance (30 mm – 300 mm), and selectable light\/dark switching modes allow seamless integration with various control systems to meet different application logic requirementsSICK.<\/li>\n
  3. Stable Sensing Performance<\/strong>: The visible red LED (650 nm wavelength) delivers a consistent light spot (\u00d8 20 mm at 300 mm), ensuring reliable detection of objects with varying colors and surface texturesSICK.<\/li>\n
  4. Efficient Response and Switching<\/strong>: With a response time of \u2264 0.5 ms and a switching frequency of 1000 Hz, it can capture medium-speed moving objects on production lines, supporting rapid and repetitive detection processesSICK.<\/li>\n
  5. Robust Environmental Adaptability<\/strong>: IP67-rated housing protects against dust and water jets, and a wide operating temperature range (-25 \u00b0C to +55 \u00b0C) ensures reliable operation in harsh industrial environmentsSICK.<\/li>\n
  6. Easy Installation and Integration<\/strong>: The M8 4-pin connector enables quick electrical connections, and the included stainless-steel mounting bracket supports flexible mounting orientations, reducing installation time in control cabinets or machinerySICK.<\/li>\n<\/ol>\n
