Product Description

The SICK WFM120-120P321 (Part Number: 6037832) is a high-performance optical fork sensor engineered for precision and ease of use in industrial automation. Housed in a durable, rugged aluminum casing, this sensor features a significant 120 mm fork width and 124 mm depth, allowing it to accommodate a wide variety of object sizes and process paths. The device utilizes a visible red LED light source, which ensures highly visible alignment and simplifies the commissioning process.

Technically, the WFM120 operates on a 10 V DC to 30 V DC power supply and provides a reliable PNP switching output in dark-switching mode. It is designed for high-speed efficiency, boasting a switching frequency of 4,000 Hz and a rapid response time of ≤ 125 µs. With the ability to detect a Minimum Detectable Object (MDO) of 0.8 mm, it offers the granular precision required for identifying small parts or gaps. The IP67-rated enclosure ensures protection against moisture and dust, making it a robust solution for demanding environments. Its plug-and-play design requires no manual adjustment, significantly reducing downtime and setup complexity.

Key Performance Features

High-Speed Response: 4 kHz switching frequency and 125 µs response time for high-throughput lines.
Precision Detection: Detects objects as small as 0.8 mm with consistent accuracy.
Rugged Design: IP67 enclosure rating and aluminum housing for industrial durability.
Simple Setup: No manual sensitivity adjustment required; “plug-and-play” installation.
Visible Alignment: Bright red LED light source allows for quick and easy positioning.
Advanced Electronics: Integrated reverse polarity and short-circuit protection for enhanced safety.

Ideal Applications

Packaging Industry: Accurate detection of labels, foils, or seals on production lines.
Electronics Manufacturing: Presence control and positioning of small components or PCBs.
Food and Beverage: Object passage detection and counting on high-speed conveyors.
Intralogistics: Monitoring of small parts and gap detection in sorting systems.
Machine Building: End-position monitoring and trigger sensing in automated machinery.
