A rotating disc with optical or magnetic patterns used to convert angular position into digital signals.

Product Specifications

Technical details and manufacturing context for Code Disc

Definition
A critical component within feedback encoders that contains precisely patterned tracks (optical, magnetic, or capacitive) which, when read by sensors, generate position or speed signals for motion control systems.
Working Principle
The disc rotates with a shaft, and sensors detect pattern changes on its surface (light/dark transitions, magnetic poles, or capacitive variations) to produce electrical pulses corresponding to angular displacement.
Common Materials
Glass, Metal alloy, Polymer
Technical Parameters
  • Diameter and thickness specifications (mm) Per Request
Components / BOM
  • Pattern Track
    Contains the encoded position information in alternating patterns
    Material: Chrome coating or magnetic material
  • Substrate
    Provides structural support and dimensional stability
    Material: Glass or metal alloy
  • Mounting Hub
    Secures the disc to the rotating shaft
    Material: Aluminum or steel
Engineering Reasoning
0-6000 RPM, -40°C to 85°C, 5-24 VDC supply voltage
Angular velocity exceeding 6500 RPM causes centrifugal deformation >0.1 mm, signal-to-noise ratio dropping below 20 dB at 5000 RPM, operating temperature exceeding 90°C causing pattern layer delamination
Design Rationale: Centrifugal force exceeding material yield strength (σ_y = 250 MPa for aluminum alloy), thermal expansion coefficient mismatch (α_disc = 23×10^-6/°C vs α_substrate = 6×10^-6/°C) causing interfacial stress >100 MPa, electromagnetic interference exceeding 50 V/m disrupting Hall effect sensor operation
Risk Mitigation (FMEA)
Trigger Contaminant particle >10 μm diameter adhering to optical pattern surface
Mode: Signal dropout exceeding 5 ms duration during rotation
Strategy: Hermetic sealing with IP67 rating, positive pressure purge system maintaining 1.5 bar internal pressure differential
Trigger Bearing wear causing radial runout >0.05 mm
Mode: Periodic signal amplitude modulation at rotational frequency harmonics
Strategy: Precision angular contact bearings with ABEC-7 tolerance, real-time runout compensation algorithm using Fourier analysis

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Abrasive wear
Cause: Prolonged exposure to particulate-laden fluids causing material removal from disc surfaces, leading to reduced sealing efficiency and eventual leakage.
Fatigue cracking
Cause: Cyclic stress from repeated pressure fluctuations or thermal cycling, initiating micro-cracks that propagate through the disc material, potentially causing catastrophic failure.
Maintenance Indicators
  • Visible scoring or deep grooves on the disc sealing surfaces
  • Unusual vibration or audible knocking during operation indicating disc instability or partial blockage
Engineering Tips
  • Implement regular fluid filtration and contamination control to minimize abrasive particle ingress
  • Establish preventive maintenance intervals based on operating cycles rather than calendar time, with thorough inspection of disc surfaces and clearances
