Manufacturer profiles associated with Code Disc.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Incremental discs have evenly spaced lines generating pulses for relative position tracking, requiring a reference point. Absolute discs have unique patterns for each position, providing immediate absolute angle data without homing.
Temperature changes cause thermal expansion/contraction, potentially altering pattern accuracy. Contamination (dust, oil) can obscure optical readings. Vibration may induce signal noise. Proper sealing, material selection (e.g., low-CTE glass), and mounting mitigate these issues.
