The Sony Magnescale SR10‑010A is a high‑resolution magnetic linear scale used for precise position feedback in motion control systems. Common failure points for this class of units include loss of signal due to damaged Hall sensor contacts, corrosion or contamination on the magnetic head surface, and degradation of the internal microcontroller or driver ICs from overvoltage or EMI exposure. Begin troubleshooting by verifying that the supply voltage matches the specified ±12 V (or 24 V) range and checking for proper ground reference; then inspect the scale’s mounting bracket and sensor head for physical damage or debris, followed by a continuity test of the Hall sensor leads and an oscilloscope sweep across the output signals to confirm correct sinusoidal patterns.[oss-gpt-20b]
