Product Description
SICK WTB9-3P2261 Background Suppression Photoelectric Sensor is an industrial-grade block sensor providing background suppression detection capabilities with a range from 20 mm up to 350 mm. It utilizes a red pin-point LED light source focused to a spot diameter of 4.5 mm at 75 mm, enabling precise sensing in automated manufacturing, packaging, and inspection systems.
The sensor features a durable Vistal plastic housing rated IP66, IP67, and IP69K to withstand dust, water, and high-pressure cleaning, making it suitable for demanding industrial environments. It supports a DC operating voltage up to 30V and has a maximum continuous current of 30mA with a PNP output signal interface using a sturdy 4-pin M8 connector for fast installation.
With a rapid response time of 333 microseconds, it enables high-speed object detection critical for conveyor systems, pick-and-place verification, and small-part detection in electronics assembly. Its operating temperature span from -40°C to 60°C ensures reliable performance under extreme environmental conditions. Sensitivity adjustment is facilitated by a 5-turn potentiometer, with LED indicators providing alignment feedback during commissioning.
Reliable detection using background suppression method for distinguishing foreground objects from backgrounds. Compact panel-mount design enhances integration flexibility in automation setups. High ingress protection levels suitable for dusty, wet, or hygienic industrial environments.
Precise red LED light source supports accurate sensing of low-reflectance items. Industry approvals including CE and cULus listing ensure safety and quality compliance. Suited for applications such as packaging presence verification, conveyor detection, and inspection stations.
Easy electrical integration thanks to PNP output and M8 connector compatibility with PLCs.
This sensor is manufactured in Germany and belongs to the W9-3 series of sensors from SICK. It is designed for industrial automation, manufacturing, packaging, and quality assurance environments requiring fast, accurate object detection with robust environmental protection.
