Product Description

The SICK 6037825 (WFM50-60P311) is a high-performance optical fork sensor designed for precise and rapid object detection in automated industrial environments. As part of the WFM series, this sensor features a “plug-and-play” design that eliminates the need for complex manual adjustments or sensitivity teaching, ensuring immediate operational readiness upon installation. The device utilizes a visible red light LED source, making alignment intuitive and straightforward.

Encased in a rugged aluminum housing with an IP67 protection rating, the WFM50-60P311 is built to withstand harsh factory conditions while maintaining exceptional accuracy. It boasts a high switching frequency of 4 kHz and a rapid response time of 125 µs, making it ideal for high-speed production lines. With a fork width of 50 mm and a depth of 60 mm, it can reliably detect small objects, with a minimum detectable object (MDO) size of 0.8 mm. This sensor provides a cost-effective, durable, and highly reliable solution for label detection, part counting, and positioning tasks where space and speed are critical.

Key Performance Features

Fast Response Time: Features a ≤ 125 µs response time and 4 kHz switching frequency for high-speed processes.
Precise Detection: Minimum detectable object (MDO) of 0.8 mm ensures accuracy for small parts.
No Adjustment Needed: Fixed sensitivity allows for immediate “out-of-the-box” operation without alignment or teaching.
Robust Design: Durable aluminum housing with an IP67 enclosure rating for resistance to dust and water.
Visible Alignment: Visible red light source allows for quick and easy positioning relative to the target object.
Integrated Protection: Includes reverse polarity protection, short-circuit protection, and interference pulse suppression.

Ideal Applications

Packaging Industry: Detection of labels on bottles, containers, or web materials.
Electronics Production: Counting and positioning of small electronic components on conveyors.
Assembly Lines: Monitoring the presence of small parts or detecting the edges of moving materials.
Printing & Paper: Triggering processes based on the detection of sheets or web edges.
Machine Building: General-purpose object counting and position sensing in compact machinery.
