Sony Magnescale SR87 Pulscale

Sony Magnescale SR87 Pulscale is a high‑precision magnetic absolute linear scale used to provide position feedback for machine tools and industrial motion systems. Common failure points in this class of devices include loss of signal due to coil winding degradation, magnetization drift from thermal cycling, and connector corrosion leading to intermittent data transmission. Initial checks should verify the power supply voltage and current ratings against spec, inspect all cable terminations for signs of wear or oxidation, and confirm that the output signals (FANUC/Mitsubishi/Panasonic/YASKAWA protocols) are within expected ranges using a loopback tester or oscilloscope.[oss-gpt-20b]
