Product Description

The SICK WF2-40B410 (Part Number: 6028428) is a high-performance fork sensor designed for demanding industrial environments where precision and speed are critical. Unlike standard photoelectric sensors, the WF2 integrates both the sender and receiver into a single rugged metal housing, eliminating the need for complex alignment and significantly reducing installation time. With a narrow 2mm fork width and a 42mm depth, it is specifically engineered to detect small objects, edges, or labels with a minimum detectable object (MDO) size of just 0.2 mm.

Equipped with an infrared light source and a rapid 100 µs response time, the sensor ensures reliable operation even in high-speed production lines reaching switching frequencies of up to 10 kHz. The user-friendly interface features intuitive plus/minus buttons, allowing for precise sensitivity adjustments and easy selection between light and dark switching modes. Its robust IP65-rated construction and high immunity to ambient light make it a dependable solution for diverse automated processes, ensuring consistent throughput and minimized downtime in sophisticated manufacturing applications.

Key Performance Features

High Switching Frequency: Operates at 10 kHz, ideal for rapid-fire detection in high-speed processes.
Precise Object Detection: Detects extremely small gaps and objects down to 0.2 mm (MDO).
Flexible Output: Dual PNP/NPN (Push-pull) switching output provides compatibility with various PLC systems.
Simple Setup: Manual adjustment via +/- buttons allows for quick onsite calibration without external software.
Superior Alignment: The fixed fork design ensures the emitter and receiver are always perfectly aligned.
Industrial Durability: Rugged aluminum housing with IP65 protection rating for harsh environments.

Ideal Applications

Labeling Machines: High-precision detection of labels on transparent or opaque carriers.
Packaging Industry: Monitoring of film edges, tear marks, or small component presence on conveyors.
Electronics Manufacturing: Accurate positioning of small parts or PCB edges during assembly.
Printing Processes: Reliable detection of register marks and paper edges.
General Automation: Counting small parts or detecting gaps in fast-moving material flows.
