Polatech 025520 autocut encoder

Polatech EMC 025‑520 autocut encoder is a high‑resolution linear position sensor used in industrial cutting and machining systems. Common failure modes for this model include contact degradation on the SMD read head, signal line corrosion, and internal PCB burn‑in due to overcurrent or voltage spikes; similar Polatech encoders also suffer from misalignment of the magnetic strip and occasional firmware glitches that manifest as erratic position outputs. Begin troubleshooting by verifying proper power supply levels (±5 VDC) and inspecting for visible damage on the board, then check the signal integrity on the encoder output lines with an oscilloscope or logic analyzer, and finally review any error codes from the host controller for indications of communication loss or calibration errors.[oss-gpt-20b]
