SICK Background Suppression Photoelectric Sensor, Block Sensor, 1 m Detection Range, NPN/PNP Output WTB16P-1H161120A00

The SICK WTB16P-1H161120A00 Background Suppression Photoelectric Sensor is a compact block style sensor designed for industrial automation and control applications. It features background suppression technology enabled by a precise pin-point LED light source that enables accurate sensing of small targets while reducing false detections caused by backgrounds. It supports both NPN and PNP output types, meeting diverse wiring requirements, and uses IO-Link V1.1 communication protocol for remote configuration and integration into control networks.

This sensor is rated IP66, IP67, and IP69K, providing superior resistance to dust, water jets, and high-pressure washdown environments, making it ideal for use in harsh industrial settings such as food processing and wash-down production lines. The device can reliably operate across a broad temperature range from -40°C to 60°C, delivering consistent performance in cold stores and heated processes.

With a response time of 500 microseconds, it is suitable for fast-moving applications including high-speed conveyors and automated assembly stations. The sensor accepts a maximum DC supply voltage of 30 V and draws a maximum current of 100 mA during operation. The durable plastic housing and hole mount type enable secure and flexible installation options.

This device carries CE and cULus certifications, ensuring conformity with key European and North American safety standards. The sensor's robust design and advanced sensing capabilities make it highly suitable for industrial automation, manufacturing, material handling, and packaging applications requiring reliable object detection and presence monitoring.
