Fiber Optic Color Sensor with Photodiode, 5-50mm

A fiber optic color sensor emits light through its built-in light source. This light is reflected or transmitted by the object being measured and enters the fiber optic cable. An optoelectronic component then detects light intensity at different wavelengths to distinguish color components such as red, green, and blue. Leveraging the flexibility of fiber optic transmission, it enables color detection in confined spaces or harsh environments. It is widely used in printing, packaging, and sorting applications.

Fiber optic color sensors are particularly well-suited for industries with special installation environment requirements. Examples include color mark recognition in printing and packaging, color consistency inspection in textiles, and sorting of plastics and bottle caps. Since the fiber optic probe can be installed in high-temperature, high-humidity, or space-constrained areas, it offers greater flexibility than conventional color sensors.

Conventional color sensors typically feature an integrated design suitable for standard industrial environments. Fiber optic color sensors, however, separate the detection head from the amplification circuitry, transmitting light via fiber optics. This results in a more compact and flexible probe. This design not only adapts to complex environments like high temperatures and strong electromagnetic interference but also enables precise installation in confined spaces, offering distinct advantages in challenging operating conditions.
