SICK Background Suppression Photoelectric Sensor, Block Sensor, 20 mm to 350 mm Detection Range, PNP Output WTB9M4-3P2261

SICK WTB9M4-3P2261 Background Suppression Photoelectric Sensor is a high-performance block sensor designed for various industrial automation tasks requiring precise and reliable object detection. It detects objects within a range of 20 mm to 350 mm, making it versatile for conveyor systems, presence detection, and sorting applications.

The sensor features background suppression technology that minimizes false triggers caused by complex or cluttered backgrounds. Its PNP output type facilitates direct interfacing with common control inputs, simplifying system integration. Constructed with a robust plastic Vistal housing and engineered for panel mounting, it withstands harsh industrial environments.

Operating temperature ranges from -40°C to 60°C ensure performance stability in diverse temperature conditions. The unit meets IP69K, IP66, and IP67 ingress protection standards, providing resistance to dust, high-pressure cleaning, and temporary immersion, suitable for washdown areas.

Equipped with an LED light source and requiring a maximum DC voltage of 30 V with a maximum current of 100 mA, this sensor offers secure and consistent operation. Its rapid response time of 330 microseconds supports use in fast process environments where timing is critical.

Background suppression reduces false detection in complex scenes. PNP output enables easy interfacing with industrial control systems. Durable plastic Vistal housing suitable for panel mounting. Wide operating temperature range from -40°C to 60°C.

Ingress protection IP69K, IP66, and IP67 certified for harsh environments. LED light source ensures accurate detection. Maximum DC voltage of 30 V and current rating of 100 mA. Fast response time of 330 μs meets high-speed application needs.

Certified by CE, cULus, and with UL NRKH.E181493 for compliance. Perfect for use in conveyor item detection, machine safety interlocks, and automated sorting operations.

This Photoelectric Sensor is essential for automation, manufacturing, packaging, and material handling industries where reliable item presence detection is paramount. Its panel-mount design ensures neat installation in control racks and automation panels. For reflective sensor applications, appropriate reflectors such as PL80A, PL30A, and C110 are recommended but sold separately.
