Product Description

The SICK 6036826 (WFL80-40B416) represents a pinnacle in precision detection technology, designed to meet the rigorous demands of high-speed industrial automation. Unlike traditional photoelectric sensors that require tedious alignment between a separate sender and receiver, this fork-shaped unit houses both components in a single, rigid aluminum frame. This “plug-and-play” design ensures that the optical axis remains perfectly aligned even under heavy machine vibration.

Utilizing a Class 1 visible red laser beam, the WFL80-40B416 can pinpoint incredibly minute objects down to 0.05 mm in size. Its ultra-fast switching frequency of 10 kHz allows it to monitor production lines moving at extreme velocities without missing a single pulse. The device is housed in a robust, IP65-rated metal casing, making it resilient against dust and moisture in harsh factory environments. Operators can easily toggle between light and dark switching modes using the integrated plus/minus buttons, providing flexible control for various material types, including transparent or highly reflective surfaces. This combination of speed, durability, and microscopic resolution makes it an essential tool for modern “smart” manufacturing workflows.

Key Performance Features

Ultra-High Speed: Switching frequency of 10,000 Hz (10 kHz) with a response time of just 100 µs.
Microscopic Accuracy: Detects objects as small as 0.05 mm (Minimum Detectable Object).
Visible Laser Beam: Class 1 laser provides a clear red spot for effortless alignment and setup.
Rugged Construction: Durable aluminum housing with an IP65 enclosure rating for industrial longevity.
Flexible Output: Supports both PNP and NPN signals, ensuring compatibility with various PLC architectures.
Ambient Light Immunity: Engineered to remain stable even in environments with high levels of artificial or natural light (up to 10,000 lx).

Ideal Applications

High-Speed Labeling: Precise detection of opaque or transparent labels on web materials.
Small Part Counting: Identifying tiny components like needles, wires, or electronic pins on assembly lines.
Packaging Industry: Monitoring double-sheet detection, holes, or tear-off edges in foil and paper processing.
Electronics Assembly: Accurate positioning of PCB edges and component verification.
Automated Sorting: High-velocity detection of falling objects or parts in feeder bowls.
