GX Colour mark sensor

About GX Colour mark sensor

A GX Colour Mark Sensor is a compact photoelectric sensor used to detect color marks or contrast differences on surfaces. It is commonly used in packaging, printing, labeling, and automatic inspection systems to identify printed marks or colored labels with high accuracy.

The sensor works by emitting light (usually red, green, or blue LED) onto a surface and measuring the reflected light intensity. When the sensor detects a specific color mark or contrast difference compared to the background, it produces an electrical signal indicating that the mark has been detected.

GX colour mark sensors are designed for high-speed and precise detection, even when objects are moving quickly on conveyors. Their compact size allows them to be installed in small spaces on industrial machines.
