Sensor Encoder Disc is a precision metal functional component used in sensing and motion control systems. Its main function is to work with optical detectors, encoders, angle sensors, or position feedback modules to convert mechanical movement into readable signals, enabling accurate detection of rotational angle, speed, direction, position, and motion status.
In optical sensor and encoder systems, scale line accuracy, hole distribution, pitch consistency, aperture shape, roundness, flatness, and surface quality directly affect signal reading accuracy and detection stability. Uneven scale lines or apertures may cause signal errors, unstable position feedback, or reduced detection accuracy. Therefore, sensor encoder discs require high processing accuracy, clean edge quality, and reliable dimensional consistency.
This product can be customized using stainless steel, copper alloy, nickel alloy, aluminum alloy, or other metal materials according to customer requirements. Stainless steel provides good mechanical strength, corrosion resistance, and dimensional stability, making it suitable for long-term use in sensors and industrial control equipment. Aluminum alloy is lightweight and suitable for detection structures requiring reduced weight. Copper alloy and nickel alloy can be selected for applications requiring conductivity, wear resistance, or specific surface performance. Outer diameter, inner hole, thickness, line count, tooth count, hole positions, positioning structures, and special encoding patterns can all be customized according to the design.
Through precision metal etching, high-accuracy light slots, scale lines, teeth, micro-hole arrays, positioning holes, and complex encoding patterns can be produced on thin metal sheets. Compared with traditional stamping or machining, chemical etching is better suited for thin metal encoder discs, fine patterns, high-density apertures, small-batch development, and high-precision customization. The process also helps reduce mechanical stress deformation, maintaining better flatness, roundness, and dimensional consistency.
Innoetch supports the custom development of different types of sensor encoder discs and encoder metal wheels based on customer drawings, including optical sensor discs, angle sensor discs, incremental encoder discs, absolute encoder discs, motor feedback discs, metal scale discs, and custom precision positioning discs. Products can also be supplied with single-sided etching, double-sided etching, half-etched structures, surface cleaning, deburring, passivation, plating, or other post-processing services according to customer requirements.
This type of product is widely used in optical sensors, angle sensors, encoders, servo motors, stepper motors, robotics, automation equipment, instruments, medical devices, industrial control systems, and precision measurement equipment. For customers who require high-precision encoding patterns, stable signal output, good flatness, and customized structures, precision etched sensor encoder discs provide a reliable, flexible, and scalable metal manufacturing solution.
