← ScienceWhich consequence results when a charged capacitive proximity sensor contaminates?
A)Reduced sensing range occurs✓
B)Increased saturation current develops
C)Uncontrolled thermal runaway initiates
D)Oscillation frequency becomes unstable
💡 Explanation
A contaminant’s increased effective dielectric causes parasitic capacitance via capacitive loading which mimics closer proximity than actual, therefore reducing the range because the contamination changes the electric field rather than thermal or saturation effects.
