Reed Switch Operate Distance Calculator
Infer bracketed reed operate distance on caller calibrated axial magnetic field versus distance; absent crossing retains unknown zero sentinel, no universal magnet inverse-power law, release hysteresis or installation range guarantee.
Description
Reed operate distance can be bracketed on a measured axial-field curve.
Reed operate distance can be bracketed on a measured axial-field curve. Lack of a crossing should remain explicitly unknown.1
Enter nonnegative strictly increasing distances and aligned nonnegative strictly decreasing fields with at least two points, plus positive threshold. Return crossing value and found flag, with zero as absent sentinel and the observed distance domain.
When to use Reed Switch Operate Distance Calculator
Use Reed Switch Operate Distance Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No universal magnet-distance law, release hysteresis or installation guarantee is supplied.
Prepare measured device or circuit evidence with matched frequency, temperature, waveform and calibration conditions. Supply explicit caller ratings and limits.
How to use Reed Switch Operate Distance Calculator and understand its results
- Prepare measured device or circuit evidence with matched frequency, temperature, waveform and calibration conditions. Supply explicit caller ratings and limits.
- Enter magnetDistancesMm, calibratedAxialFieldMillitesla, callerReedOperateFieldMillitesla using the field table and calculation rules, then run the tool.
- Read bracketedOperateDistanceMm, operateThresholdBracketed, observedDistanceDomainMm. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| magnetDistancesMm | Magnet distances mm | list of number | Required |
| calibratedAxialFieldMillitesla | Calibrated axial field millitesla | list of number | Required |
| callerReedOperateFieldMillitesla | Caller reed operate field millitesla | number | Required |
Enter nonnegative strictly increasing distances and aligned nonnegative strictly decreasing fields with at least two points, plus positive threshold. Return crossing value and found flag, with zero as absent sentinel and the observed distance domain.
distance=piecewise-linear crossing(field,operateThreshold) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| bracketedOperateDistanceMm | Bracketed operate distance mm | number |
| operateThresholdBracketed | Operate threshold bracketed | boolean |
| observedDistanceDomainMm | Observed distance domain mm | list of number |

}Limitations and assumptions
No universal magnet-distance law, release hysteresis or installation guarantee is supplied.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
Alternative or Complementary methods
Use Proximity Sensor Range Calculator: A sensor range criterion can be located on target-specific measured detection fractions. Observed range endpoints expose censoring. For a complementary task, use Hall Sensor Switch Point Calculator: A Hall Schmitt switch keeps state between operate and release thresholds. Initial state therefore matters.
