Product Description

The SICK WFM50-60P321 (part number 6037824) is a high-performance, “plug-and-play” photoelectric fork sensor designed for rapid and reliable object detection. Unlike traditional through-beam sensors, the WFM series integrates the transmitter and receiver into a single rugged aluminum housing, eliminating the need for complex alignment and reducing installation time significantly.

With a generous fork width of 50 mm and a depth of 60 mm, this sensor is engineered to detect even small, fast-moving parts with a minimum detectable object (MDO) size of 0.8 mm. It operates using a highly visible red light source, which aids in quick setup and positioning. The device is factory-preset, meaning no additional sensitivity adjustments are required, ensuring stable performance right out of the box. Its PNP dark-switching output and high switching frequency of 4,000 Hz make it an ideal solution for high-speed industrial processes. Built with an IP67-rated metal housing, the WFM50-60P321 provides exceptional durability and resistance to environmental factors, making it a dependable choice for demanding automated production lines where space and precision are critical.

Key Performance Features

Plug-and-Play Setup: Fixed sensitivity and integrated alignment allow for immediate commissioning without manual adjustments.
High Switching Frequency: A 4 kHz frequency enables precise detection in high-speed applications with a response time of 125 µs.
Visible Red Light: The bright red LED light spot allows for easy visual verification of the switching point.
Robust Construction: Durable aluminum die-cast housing with IP67 protection ensures longevity in harsh industrial environments.
Small Object Detection: Capable of identifying objects as small as 0.8 mm with high repeatability.
Integrated Circuit Protection: Features reverse polarity, short-circuit, and interference pulse suppression.

Ideal Applications

Labeling and Packaging: Detection of labels on bottles or containers and monitoring film edges.
Production Lines: Counting and detecting small metal or plastic parts on conveyor systems.
Assembly Automation: Monitoring the presence of components in feeder bowls or pick-and-place stations.
Electronics Manufacturing: Precise detection of PCB edges or lead frames during processing.
Print Industry: Identifying marks or edges on continuous paper or textile webs.
