Are color and distance roadblocks to detection? How does the FB5W small limited reflective sensor intelligently detect all black, white, and transparent materials?

In the field of industrial automation, accurate object detection has always been a core challenge—especially when dealing with varying colors, complex backgrounds, or transparent materials. Fuwei Intelligent's FB5W series reflective sensor emerges as a solution, breaking through the perception boundaries of traditional photoelectric sensors with its revolutionary optical design, and providing stable and reliable detection solutions for complex scenarios.

Subverting Tradition: Colors and Materials Are No Longer Obstacles

Traditional photoelectric sensors often fail due to color differences in objects: when calibrated for white, they may miss black objects; conversely, they are prone to interference from white backgrounds. The FB5W series reflective sensor achieves remarkable color stability through its unique optical system design. Whether it is mirror-reflective materials, deep black objects, or transparent glass/films, it can accurately detect their presence. This feature makes it highly effective in scenarios such as detecting transparent pharmaceutical packaging bags, identifying dark coffee cups, and inspecting items inside express boxes.

Precise Definition: Limited Reflection Principle Builds a Perception Moat

The core advantage of this reflective sensor lies in its "limited reflection" working principle:

→ Precisely controls the overlapping range of the projected light beam and the light-receiving area

→ Only detects objects within a specific distance in front of the sensor (black: 5-40mm; white: 5-60mm; transparent: 5-50mm)

→ Completely shields background interference to avoid false triggers

This "spatial filtering" capability enables it to excel in scenarios requiring precise position judgment, such as hand detection in hygiene devices and monitoring of robotic arm working ranges.

Optical Innovation: Toroidal Lens Array Empowers Stable Detection

The FB5W series is equipped with Fuwei Intelligent's exclusively designed four-layer toroidal lens system, a masterpiece of optical engineering:

✓ High-efficiency light concentration: Focuses and enhances weak light, significantly improving signal-to-noise ratio

✓ Distance stability: Maintains stable detection even if the object's position shifts

✓ Strong adaptability: Covers a wide range from 5mm to 60mm, compatible with black, white, and transparent materials

The "distance-color" dual stability ensures reliable operation even in vibrating environments or when incoming materials fluctuate in position.

Widespread Application: Cross-Scenario Use of Intelligent Detection

Currently, this high-performance reflective sensor has demonstrated value in multiple key fields:

► Medical equipment: Ensures accurate positioning of transparent bags in pharmaceutical packaging machines

► Food and beverage: Precisely identifies cups of different colors in coffee machines

► Logistics sorting: Reliably detects the status of fillers in dark express boxes

► Hygiene devices: Non-contact hand presence sensing to improve hygiene standards

The FB5W series redefines the performance benchmark for small photoelectric sensors with its breakthrough optical design and intelligent detection logic. It is not only a cornerstone of perception in the Industry 4.0 era but also a key component ensuring the reliability of the "last centimeter" in automated systems. Choosing this reflective sensor means choosing stability, precision, and endless possibilities.
