Precision Component Etching Processing - Film/Resin/Film Code Disc

Product Name: Film Code Disc, Resin Code Disc, Film Code Disc

Product Material: Photoplotting Film (Fuji, Kodak KODAK, HPR-7S, AGFA, etc.)

Standard Thickness: 0.7mm, 1.0mm, 1.1mm, 2.0mm, 3.0mm

Process Advantages:

1. Pulse lines are uniform, vertical, and smooth, with no connections or breaks;

2. High precision, no limit on pulse count, small line size can be as fine as 0.01mm;

3. Strong shock resistance, with extremely high mechanical strength and pressure resistance;

4. Reflective materials can be added to create reflective code discs;

Precision: Tolerance ±0.002mm (i.e., 2 micrometers);

Delivery Cycle: Standard sampling 3-5 days, delivery 5-7 days.

Application: Digital encoder for measuring angular displacement. It offers strong resolution, high measurement accuracy, and reliable performance, making it a commonly used displacement sensor for measuring shaft rotation angle.

A code disc (grating disc) has several rectangular holes evenly distributed on a circular plate of a certain diameter. Since the photoelectric code disc is coaxial with the motor, when the motor rotates, the code disc (grating disc) rotates at the same speed as the motor. The detection device, composed of electronic components such as light-emitting diodes, detects and outputs several pulse signals. By calculating the number of pulses output by the photoelectric encoder per second, the current speed of the motor can be determined.
