The Encipheror Optical Grating Encoder Disk is a precision component essential to rotary encoder systems, designed to accurately measure angular displacement in a wide range of industrial and electronic applications . As a critical element of digital encoders, it offers strong resolving power, high measurement accuracy, and reliable operation, making it one of the most commonly used displacement sensors for determining shaft rotation angles .
Encoder disks are generally classified into two types: absolute encoders, which directly provide the digital code corresponding to angular position, and incremental encoders, which generate pulse increments that are calculated against a reference point to determine movement . The optical grating pattern on the disk—comprising precisely etched through-lines and opaque sections—interrupts or transmits light to create these position-defining signals.
Manufactured from SUS304 stainless steel through advanced photochemical etching, this encoder disk achieves exceptional flatness below 0.02mm and completely burr-free edges, ensuring consistent performance even in demanding environments . The metal construction offers superior durability compared to glass alternatives, resisting breakage while maintaining dimensional stability across temperature variations .
Widely utilized in motors, hardware systems, electrical appliances, and automotive applications, the stainless steel encoder grating provides reliable position feedback essential for precise motion control . Its ability to perform in harsh conditions while maintaining micron-level accuracy makes it an indispensable component in modern automation and sensing technologies.
