Sensor Debounce Calculator
Calculate debounce time for proximity sensors and PLC input filtering. Prevent false triggers and ensure reliable sensor readings in industrial applications.
Debounce Time Guidelines
Proximity Sensors
Typically 5-20ms. Adjust based on sensor response time and environmental noise.
Mechanical Switches
Typically 20-100ms. Longer debounce needed due to contact bounce.
PLC Implementation
Debounce time should be at least 2-3 times the PLC scan time. Use timer or counter-based debounce logic.
Noise Considerations
If noise frequency is known, debounce time should be at least 2.5 times the noise period to filter out false triggers.
