The WFM30-40P311 Sick 30 mm Width Fork Sensor is a compact optical fork sensor designed for object detection in industrial automation systems. This model combines a 30 mm fork width, 42 mm fork depth, and 0.8 mm minimum detectable object to support accurate detection of small parts. Operating at a 4 kHz switching frequency, the WFM30-40P311 belongs to the WFE series and uses a PNP output suitable for common control interfaces.
In industrial environments, the WFM30-40P311 Sick 30 mm Width Fork Sensor is applied in conveyors, packaging machinery, counting systems, and automated assembly processes. The fixed fork geometry enables consistent detection of passing objects without alignment complexity. Red LED illumination and dark switching mode help maintain stable output signals during continuous operation in production lines.
The WFM30-40P311 from Sick provides defined electrical characteristics, IP67-rated metal housing, and integrated circuit protection for long-term industrial use. With an M8 connector interface, controlled output current, and compatibility within the WFE series, this Sick fork sensor aligns with automation system requirements. These specifications confirm the WFM30-40P311 as a reliable fork sensor choice for industrial automation applications.
