Product Description
The SICK WL9-3P3430 Retroreflective Photoelectric Sensor is engineered for demanding industrial sensing applications, where accurate and reliable object detection is critical. Featuring a block-style compact housing, this sensor is constructed with robust Vistal plastic, enhancing resistance to mechanical shocks and corrosive cleaning procedures in manufacturing, packaging, and automation environments.
Its retroreflective light beam technology allows detection of objects up to 4 meters away by reflecting light back from a mounted reflector. The sensor outputs PNP logic, making it compatible with sourcing automation controls and programmable logic controllers for seamless integration.
Designed for wet and aggressive processes, the enclosure is rated IP66, IP67, and IP69K, offering protection against high-pressure, high-temperature washdown and dust ingress. This enables usage in food and beverage lines, chemical production, and facilities with rigorous cleaning requirements.
The WL9-3P3430 supports a wide temperature range of -40 to 60 degrees Celsius, ensuring operation in cold storage warehouses, assembly areas, and heat-intensive production zones. With a fast response time of 500 microseconds, it is ideal for conveyor tracking, product counting, position control, and automated machine end-of-travel sensing.
An integrated four-pin connector provides standardised wiring for power and output signals, simplifying installation and maintenance. The unit operates with an LED light source, delivering stable signals and long-term sensing reliability.
Industrial applications include conveyor presence detection, pallet tracking, high-speed assembly counting, and wet-clean environments across manufacturing, laboratory automation, process control, commercial packaging, and HVAC systems.
The SICK WL9-3P3430 meets EN IEC 63000 certification for EU technical compliance and is manufactured in Germany. Its advanced protective housing and high-precision electrical characteristics make it a preferred choice in industrial automation projects.
