Product Description

The SICK WFM180-120N311 (Part No. 6037839) is a high-performance, optical fork sensor designed for rapid and precise object detection in automated industrial environments. As part of the WFM product family, this sensor utilizes a “plug-and-play” principle, eliminating the need for complex alignment between the sender and receiver. With a generous fork width of 180 mm and a depth of 124 mm, it is ideal for monitoring wider production lines or detecting larger components without sacrificing precision.

Constructed with a rugged aluminum housing, the WFM180-120N311 is built to withstand demanding conditions, boasting an IP67 enclosure rating. It features a visible red light LED source, allowing for easy visual confirmation of the light spot and straightforward alignment. The sensor delivers an impressive switching frequency of 4 kHz and a response time of just 125 µs, ensuring reliable detection even at high machine speeds. This specific NPN-output model provides a minimum detectable object (MDO) size of 1 mm, making it a dependable solution for labeling, packaging, and assembly applications where accuracy and speed are paramount. Its standard M8 3-pin connector ensures efficient integration into existing industrial control systems.

Key Performance Features

Plug-and-Play Design: Integrated sender and receiver ensure immediate operation without manual alignment.
High Switching Frequency: Operates at 4 kHz, supporting high-speed manufacturing and sorting processes.
Precision Detection: Minimum detectable object (MDO) of 1 mm for tracking fine components or labels.
Rugged Construction: Durable aluminum housing with an IP67 rating protects against dust and water ingress.
High Visibility: Bright red LED light spot allows for quick visual checks and easy setup.
Reliable Stability: Response time stability of ± 15 µs maintains consistent performance during long shifts.

Ideal Applications

Labeling Machines: Detecting labels on various container sizes within the 180mm fork width.
Packaging Industry: High-speed counting and position monitoring of boxes or materials.
Automated Assembly: Detecting the presence or absence of small parts on wider conveyor systems.
Logistics & Sorting: Tracking packages and identifying gaps in product flow.
Electronics Manufacturing: Monitoring component placement on high-speed production lines.
