Product Description
SICK WTB11-2P2431 Background Suppression Photoelectric Sensor is a block-style sensor engineered for precise object detection in industrial automation and control applications. Utilizing a red light source, it effectively suppresses background interference across a detection range of 20 mm to 350 mm.
Designed with a durable plastic ABS housing, the sensor offers IP66, IP67, and IP69K ingress protection standards, ensuring reliable operation in dusty environments and resistance against powerful washdowns and immersion. The sensor's compact screw-mount mount type allows for secure installation even in tight spaces.
Operating over a voltage range up to 30 V DC with a maximum current rating of 100 mA, the sensor features a PNP output that facilitates straightforward interfacing with PLCs and other control devices. It supports a wide temperature range from -30°C to 60°C, suitable for varied factory floor conditions.
The sensor responds rapidly with a 2.5 millisecond response time, making it ideal for moderate-speed detection tasks such as presence verification on conveyor lines, parts counting in assembly, and position sensing in material handling systems. It carries CE and UL certifications, supporting its suitability for compliant industrial installations.
Its design and ruggedness make it especially useful in food processing lines, packaging machinery, and mechanical assembly where reliable background suppression is critical. The sensor meets the EN IEC 63000 hazardous area certification.
