The VRE‑P062SAL‑S02 is a single‑turn absolute position sensor (electro‑mechanical encoder) from NSD/Absocoder, featuring a 12‑bit resolution (4096 counts per revolution) and a 9‑pin connector for power, ground, and signal outputs. Common failure modes in this class include loss of magnetic coupling due to shaft misalignment or contamination, contact wear on the output pins leading to intermittent signals, and internal winding shorts that cause voltage drops or erratic position readings. For troubleshooting, first verify the supply voltage (typically 24 VDC) and check for proper grounding; next inspect the connector pins for corrosion or looseness and perform a continuity test across the encoder windings; finally review any diagnostic error codes from the host controller and compare the output waveform to expected sinusoidal patterns.[oss-gpt-20b]
