With a standardized 5mm U-groove detection width, this sensor is the ideal solution for engineers and system integrators who require consistent performance in detecting small components, precise positioning, and motion control.

Whether your application involves detecting the origin of a linear actuator, monitoring the rotational speed of a shaft, or ensuring the synchronized movement of guide rails, the FW25 Series provides a robust and intelligent sensing solution. Built with high-quality electronic components and designed for longevity, this sensor minimizes downtime and maximizes operational efficiency, making it a cornerstone for modern automated systems.

Key Features and Engineering Excellence

1. Precision 5mm U-Groove Detection

The core of the FW25 Series is its precisely engineered 5mm groove width. This compact yet effective design allows for the detection of very small objects, thin flags, or actuator tabs that pass through the slot. The through-beam sensing principle within the groove ensures high immunity to ambient light and surface reflectivity, providing a stable and reliable signal even in challenging conditions. This makes it perfect for applications requiring exact positional accuracy, such as origin detection in linear guides or counting teeth on a small gear.

2. Intelligent Chip for Enhanced Performance

At the heart of every FW25 sensor lies a sophisticated intelligent chip. This integrated circuit elevates the sensor beyond basic functionality by providing:Stable Output: Consistent switching points unaffected by minor voltage fluctuations or temperature variations.Fast Response Time: Capable of detecting high-speed events, essential for rotational speed detection and high-cycle machinery.Built-in Diagnostics: The chip can often monitor its own performance, contributing to predictive maintenance strategies.

This smart technology ensures that the FW25 doesn't just sense—it thinks, adapting to provide reliable data for your control system.

3. Robust Integral Housing Structure

Durability is non-negotiable in industrial environments. The FW25 Series features a one-piece, integral housing structure that provides an exceptional protective effect. This monolithic design offers:High Ingress Protection (IP) Rating: Effectively sealed against dust, oil, and coolants, ensuring reliable operation in dirty or wet conditions.Mechanical Strength: Withstands vibration, shock, and accidental impact, protecting the sensitive internal components.Long-Term Reliability: The sealed housing prevents internal contamination, a common failure point in lesser sensors, significantly extending the product's service life.4. Multiple Styles for Flexible Integration

We understand that no two applications are identical. The FW25 Series is available in multiple styles and configurations, allowing you to purchase the perfect sensor for your specific working scenario. Choose from different output types (e.g., NPN, PNP, NO, NC), cable or connector versions, and sensing ranges to seamlessly integrate into your existing PLC, microcontroller, or other control systems.

Comprehensive Application Scenarios

The versatility of the FW25 U-groove sensor makes it a go-to component across numerous industries, including packaging, material handling, CNC machining, and assembly automation.Detection of Guide Rail Movement Speed: In linear motion systems, a flag mounted on a moving carriage can pass through the U-groove. By counting the pulses over time, the FW25 can accurately calculate the linear speed of the guide rail, enabling speed monitoring and control.Detect the Origin and Over-travel of a Moving Body: The sensor is perfectly suited for homing sequences. A tab on a linear actuator or robot arm passes through the groove, providing a precise "home" or "origin" signal to the controller. Additionally, a second sensor can be placed at the end of the travel to detect over-travel, preventing mechanical damage and ensuring operational safety.Detect the Origin and Rotational Speed of a Rotating Body: Mount a single tab or a multi-toothed wheel on a rotating shaft. As each tab passes through the 5mm groove, the FW25 generates a pulse. A single pulse per revolution provides origin data, while multiple pulses allow for accurate rotational speed calculation (RPM), essential for motor control and process monitoring.Use with Mounting Bracket Baffles for Positioning: Many systems use simple, fixed baffles. The FW25 can be paired with its mounting bracket or custom fixtures to detect the presence or position of these baffles, creating a simple and cost-effective limit switching system.
