optical encoder disc

Glass Code Plate Glass code disc is the core component for signal transmission in photoelectric encoders,usually made of transparent glass material with a series of engraved lines or optical patterns formed on its surface through precision processing.It is an important element in modern precision ...

Film Code Disk A film code disk is an encoding disc made of transparent plastic film or similar material, commonly used as the core component of position and speed sensors in photoelectric encoders. Similar to glass code disks, it encodes signals through precise patterns or engraved lines. Due to ...
