Product Description

The SICK WF15-40B410 (6028430) is a high-performance optical fork sensor from the WFnext series, designed for demanding industrial automation tasks. This sensor integrates the sender and receiver into a single robust aluminum housing, eliminating the need for complex alignment and reducing installation time. With a 15mm fork width and 42mm depth, it provides a compact yet versatile sensing area.

Operating on an infrared light source, the WF15-40B410 offers exceptional immunity to ambient light, ensuring reliable performance in varied lighting conditions. It features a remarkably fast response time of ≤ 100 µs and a switching frequency of 10 kHz, making it capable of detecting small objects (MDO of 0.2 mm) and labels moving at high speeds. The device is user-friendly, allowing operators to adjust sensitivity and toggle between light/dark switching via simple plus/minus buttons. Its IP65 enclosure rating and wide operating temperature range (-20 °C to +60 °C) guarantee longevity in harsh manufacturing environments.

Key Performance Features

Ultra-Fast Response: A switching frequency of 10 kHz and response time of 100 µs for high-speed applications.
Precision Detection: Minimum Detectable Object (MDO) of 0.2 mm ensures accuracy for thin edges and small parts.
Infrared Technology: LED infrared light source provides superior immunity to ambient interference.
Easy Configuration: Manual adjustment via plus/minus buttons with a clear function signal indicator (yellow LED).
Versatile Output: Dual PNP/NPN switching output and selectable light/dark switching modes.
Industrial Durability: Rugged aluminum housing with IP65 rating against dust and water ingress.

Ideal Applications

Labeling Machines: High-speed detection of labels on web materials, even with transparent or metallic finishes.
Packaging Industry: Detecting gaps, holes, or edges of packaging films and cartons.
Electronics Assembly: Monitoring the presence and position of small components on conveyor belts.
Printing Processes: Precise mark detection and edge control on high-speed printing presses.
Object Counting: Reliable counting of small parts in pharmaceutical or food processing lines.
