Does FSD26 Laser Displacement Sensor Reshape Industrial Inspection Standards with Micron-Level Precision?

In the field of precision manufacturing, an error of just 0.1 millimeters can render a product unusable, and traditional measurement methods often fail to meet the stringent requirements of modern industry. Fuwei Electronic Technology's newly launched FSD26 laser displacement sensor delivers a revolutionary breakthrough in industrial inspection with its ultra-high linear accuracy of ±0.1% F.S. and repeatability of up to 2 μm.

Exceptional Performance, Precise Measurement with No Blind Spots

The FSD26 series offers a wide measurement range from 26 millimeters to 294.98 millimeters, covering the inspection needs of everything from tiny electronic components to large mechanical parts. Its core advantage lies in its breakthrough measurement accuracy—linear accuracy as high as ±0.1% F.S. In the FSD26-30-AR model, linear accuracy even reaches ±0.008 millimeters.

The sensor uses a 655nm red laser light source with a spot diameter as small as 80×180μm (near end), combined with a maximum sampling frequency of 3KHz, enabling precise capture of minute displacement changes in high-speed moving objects. Whether for real-time monitoring of roll material remaining quantities or precise measurement of substrate curl, the FSD26 provides reliable data support.

Compact design, excels in confined spaces

In industrial settings, installation space is often limited. The FSD26 features a compact design (60×50×22 mm) with a total weight of just 120 grams (including cables), making it lighter than comparable products. Its miniaturized design allows seamless integration into confined spaces such as robotic arms and automated production lines.

The ultra-small light spot design at the sensor's front end enables precise measurement of small targets, performing exceptionally well in applications such as detecting the insertion depth of precision guide columns. The four-digit LED display combined with four buttons allows for multifunctional, simple settings, ensuring intuitive and convenient operation.

Versatile output, stable operation in industrial environments

The FSD26 offers multiple signal output options to meet diverse industrial application requirements:

Switching output: NPN and PNP switchable to accommodate different PLC interface requirements

Analog output: 4-20mA current or 0-10V voltage selectable to suit various control systems

Digital communication: RS485 interface (supporting ModBus RTU protocol) with addressable networking capability for multi-sensor network monitoring

In harsh industrial environments, the FSD26 features an IP67 protection rating, effectively resisting dust and water ingress. It has passed 10-55Hz vibration testing and 50G shock testing, maintaining stable operation even in high-vibration environments such as automotive manufacturing and metal processing.

Wide application range, versatile intelligent detection

In the field of industrial automation, the FSD26 demonstrates strong adaptability:

Coil material remaining quantity monitoring: Real-time monitoring of coil diameter changes to achieve precise material supply control

Substrate curl detection: High-precision measurement of substrate flatness to ensure product quality

Guide post insertion depth measurement: Micron-level precision control for precision assembly processes

Product presence detection: Reliably identifies extremely small components on conveyor belts to prevent missed inspections

For thickness measurement applications, the FSD26 can be used in tandem with another unit to achieve non-contact thickness detection through synchronized measurement. The key is to ensure that the light beams from both sensors are coaxial and to select laser sensors with synchronization functionality to obtain precise measurement results.

The future-oriented industrial eye

The FSD26 laser displacement sensor from Fuwei Electronics redefines the standards for industrial displacement measurement with its micron-level precision, compact design, and robust environmental adaptability. It integrates precision optics, digital signal processing, and industrial protection technology to address the challenges of balancing accuracy, measurement range, and environmental adaptability that traditional sensors struggle with.

As the Industrial 4.0 era progresses, the FSD26 will become a critical sensing component for achieving intelligent and flexible production, providing precise data support for the transformation and upgrading of manufacturing. In today's pursuit of “zero-defect” production, Fuwei Electronics illuminates the intelligent eye of industrial quality control with precise laser technology.
