Introduction

Fuke Precision offers etched metal encoder disc manufacturing, providing critical precision encoder components for driver-assistance and autonomous driving systems. These discs feature fine etched lines or patterns arranged at precise angular intervals to form a grating structure. When the grating encoder rotates or moves with a moving component, light passing through the grooves on the encoder generates alternating light and dark signals. These signals are received by photoelectric sensors and converted into electrical signals, which are used to measure parameters such as position, speed, and angle. Grating encoders are widely used in automation equipment, CNC machine tools, robots, precision instruments, and other fields.

Metal encoders feature engraved marks indicating "open" and "closed" positions; they are shatter-resistant, corrosion-resistant, and resistant to deformation, offering high precision and withstanding extreme hot and cold environments.
