Product Description
The SICK WTB9-3P2461 background suppression Photoelectric Sensor is engineered for industrial automation applications requiring precise object detection within a range of 20 mm to 350 mm. Featuring a block sensor style and LED light source, it supports both NPN and PNP output types, allowing flexible interfacing with sourcing or sinking input control systems.
Designed for panel mounting, the sensor is housed in robust Vistal plastic that offers a smooth surface finish ideal for hygienic environments such as food processing stations exposed to aggressive washdowns. It meets stringent ingress protection ratings of IP66, IP67, and IP69K, enabling resistance to high-pressure and high-temperature cleaning processes common in industrial settings.
Operating reliably between minus 40 degrees Celsius and 60 degrees Celsius, the sensor provides a rapid 333 microsecond response time ensuring swift detection for conveyor object counting and presence verification tasks. Electrical specifications include a maximum 30 V DC supply voltage and a 100 mA maximum current, supporting direct interfacing with small loads.
This W9 series sensor complies with important industrial standards such as ACMA, DIN EN 62471, RoHS, and UK regulations, ensuring both optical safety and hazardous substance restrictions are met for safe and compliant deployment.
Applications range from automated conveyor object counting lines and robot cell part verification to presence detection on packaging machinery and use in hygienic food processing environments. The sensor's durable construction and advanced background suppression technology make it ideal for demanding industrial use cases.
Dual NPN and PNP outputs facilitate versatile electrical integration. High ingress protection ratings allow use in washdown and harsh environments. Wide temperature tolerance ensures consistent performance under varying conditions.
Compact and hygienic design minimizes contamination risks in sensitive settings. Reliable rapid detection with 333μs response time supports high-speed automation. Durable Vistal plastic housing withstands industrial cleaning procedures.
Panel mount style with 4-pin M12 terminal guarantees secure connectivity. Conforms to relevant safety and environmental standards for industrial use. Explore the range of SICK sensors and automation products on EnvMart for robust industrial control solutions.
