Product Overview

The SICK WFM fork sensor is a double-fork proximity sensor designed as an all-in-one solution for shuttle positioning in industrial automation systems. Integrated sender and receiver units eliminate the need for separate components or complex alignment procedures, enabling fast setup and reliable detection performance. With a compact, rugged aluminum housing, the WFM series offers robustness in demanding environments while maintaining ease of installation. Available in five distinct designs, these sensors support fork widths from 30 mm to 180 mm and fork depths ranging from 40 mm to 120 mm, making them adaptable to a wide range of shuttle and positioning applications. The sensor’s intuitive design ensures quick integration into existing systems without compromising accuracy or reliability.

Key Features and Technology

The WFM sensor features an integrated sender-receiver configuration that simplifies installation and reduces setup time significantly. This all-in-one design eliminates alignment challenges typically associated with separate sensor components, ensuring consistent and repeatable detection performance. The yellow receive indicator is clearly visible around the entire housing, providing immediate visual feedback on switching behavior—critical for operators to verify proper operation at a glance. This visibility enhances troubleshooting efficiency and supports real-time monitoring during system operation. With no need for complex mechanical alignment, the WFM delivers reliable detection with minimal maintenance requirements, making it ideal for dynamic or high-frequency shuttle positioning tasks in automated environments.

Technical Characteristics

The SICK WFM fork sensor is built with a rugged aluminum housing to ensure durability under harsh industrial conditions. The integrated sender and receiver design allows for compact, space-efficient installation while maintaining high detection accuracy. Available in five different configurations, the sensors offer fork widths ranging from 30 mm to 180 mm and fork depths between 40 mm and 120 mm. This range enables precise customization to match specific shuttle or positioning system geometries. The sensor’s design ensures reliable performance across a variety of operational conditions without requiring external power supplies or complex wiring setups, making it suitable for both fixed and mobile automation applications.

Configuration and Integration

The WFM fork sensor is designed for straightforward integration into existing industrial systems. Due to the integrated sender-receiver structure, no additional alignment steps are required during installation, reducing setup time and minimizing potential errors. The modular design allows users to select a configuration that matches their specific fork dimensions—whether 30 mm to 180 mm in width or 40 mm to 120 mm in depth—ensuring optimal fit and function. Integration is simplified by the sensor’s compact form factor and clear visual indicators, such as the yellow receive indicator, which provides real-time feedback on switching status without relying on external monitoring tools.
