Product Description

The SICK WFL120-60B416 represents a pinnacle of optical precision in the realm of automated detection. Unlike traditional photoelectric sensors that require separate alignment of a sender and receiver, this “fork” design integrates both into a single, rigid frame. This ensures that the 120mm sensing gap is permanently aligned, eliminating common maintenance headaches caused by vibration or shifting.

Equipped with a Class 1 visible red laser, the sensor produces an incredibly small and consistent light spot. This allows it to identify microscopic changes in the light path, making it ideal for high-speed counting or detecting the edges of semi-transparent films. The device operates on a 10–30V DC supply and provides a rapid response time, ensuring accuracy even on fast-moving production lines. Its user-friendly interface allows for manual sensitivity adjustments, while the dual PNP/NPN output logic ensures it can be integrated into almost any existing PLC or control architecture without compatibility issues.

Key Performance Features

High-Speed Switching: Capable of high switching frequencies (up to 10 kHz) for rapid throughput applications.
Visible Laser Spot: The Class 1 laser beam is easily visible, making commissioning and alignment with target objects effortless.
Fixed Alignment: The “U” shaped aluminum housing maintains perfect optical alignment, even under heavy mechanical stress.
Smallest Detectable Object (MDO): Exceptional resolution allows for the detection of objects as small as 0.05 mm.
Versatile Switching: Includes both Light and Dark switching modes to suit various process requirements.

Ideal Applications

Labeling Machines: Detecting gaps between labels on a carrier web, even with transparent materials.
Packaging Industry: High-speed counting of small parts or monitoring thin film presence.
Electronics Assembly: Precision positioning of PCBs or detecting tiny components on a conveyor.
Printing & Paper: Monitoring edge guides or detecting breaks in continuous paper webs.
Quality Control: Checking for the presence of needle-thin needles or wires in medical or industrial manufacturing.
