Alias size conversion
1.59 x 0.79 mm
1/16 in diameter by 1/32 in thick is a micro magnet size, so gap discipline is critical.
Check whether a diametrically magnetized cylinder, including a 1/16 x 1/32 diametric magnet, is plausible for a Hall, reed, or magnetometer layout before you freeze the drawing.
Quick sizing tool
The default preset is the alias query size: a 1/16 x 1/32 diametric magnet. Change the dimensions, gap, grade, and sensor family to get a deterministic first-pass result.
0.0625 in equals 1/16 in.
0.03125 in equals 1/32 in.
Include housing, adhesive, and sensor package stand-off.

A 1/16 x 1/32 diametric magnet is a micro magnet. It can be useful for compact Hall switching, but the mounting gap and polarity orientation usually matter more than grade alone.
Next step
Prototype on/off detection, index pulses, door or cover state; Check the exact BOP/BRP thresholds and sampling rate in the chosen datasheet.

Report summary
The tool answers immediate sizing intent; the report below explains the assumptions, limits, and RFQ evidence needed to make the result trustworthy. Updated June 10, 2026.
90 deg
field axis shift vs axial magnet
The north and south poles sit across the curved diameter, so the usable field changes as the cylinder rotates.
1.59 x 0.79 mm
nominal metric conversion
A 1/16 in diameter by 1/32 in thick diametric magnet belongs on this canonical sizing page because the decision is still about diametric orientation, gap, and sensor match.
<3 mm
practical prototype gap target
For sub-2 mm magnets, adhesive, package stand-off, and housing thickness can consume the field margin before grade changes solve the problem.
100%
assembly stack-up must be tested
Supplier magnetization labels are not enough; Hall operate/release points, reed sensitivity, and final assembly tolerance must be tested together.
Pending
public field-at-gap data
Public data can verify unit conversion, magnetization orientation, and sensor terminology. Exact mT at a 1/16 x 1/32 in assembly gap remains pending confirmation until measured in the final fixture.
The checker converts inch dimensions to millimeters, applies a grade multiplier, penalizes very small magnet volume, estimates open-air field decay with gap, and compares the result with a sensor-family target. It is intentionally conservative for micro magnets.
The result should not be used as a certified field value. Steel brackets, adjacent magnets, package stand-off, temperature, and magnetizer variation can shift final readings, so prototype measurement remains required.
Product reference
The selector is a screening tool. For a 1/16 x 1/32 in diametric magnet or any compact sensor target, final approval still depends on the actual magnet lot, sensor threshold, housing wall, adhesive thickness, nearby steel, and temperature profile.
Micro-size decision check
The exact conversion is fixed; the magnetic field at the sensor is not. Treat this size as a prototype starting point unless a supplier provides fixture-specific measured data.
| Decision question | Evidence-based answer | Action |
|---|---|---|
| Is the 1/16 x 1/32 in size itself credible? | Yes for short-gap cues and compact fixtures; it is not credible as a long-gap actuator without measurement. | Keep the first prototype gap near 1 mm when possible. |
| Can N52 compensate for loose mechanics? | Only partly. Grade changes are smaller than the field loss caused by increasing gap on a sub-2 mm magnet. | Reduce stand-off, increase magnet volume, or change the sensing geometry before relying on grade alone. |
| What public claim should be avoided? | Avoid claiming a guaranteed mT value at a specific gap for this micro size unless the supplier provides measured data for the same fixture. | Mark field-at-gap values as pending confirmation until fixture data exists. |
| Evidence source | Time marker | How to use it | Known boundary |
|---|---|---|---|
| NIST SI unit guidance | Current public guidance checked June 10, 2026 | Use the exact inch relationship for conversion: 1 in = 25.4 mm, so 1/16 in = 1.5875 mm and 1/32 in = 0.79375 mm. | This proves size conversion only; it does not predict magnetic flux density. |
| Diametric magnet supplier drawings | Catalog convention checked June 10, 2026 | Confirm that diametric magnetization places north and south poles across the cylinder diameter rather than on the flat faces. | Supplier drawings are useful for polarity orientation, but open catalog pages rarely certify mT at the buyer assembly gap. |
| Hall, reed, and magnetometer datasheets | Device-family terms checked June 10, 2026 | Use operate point, release point, hysteresis, linear range, saturation, and temperature drift as acceptance thresholds. | Threshold units and test conditions differ by device family, so the page tool uses screening baselines rather than part-specific limits. |
| Prototype gaussmeter or sensor fixture | Required before drawing release | Measure the final assembled gap, polarity, and signal repeatability across tolerance and temperature extremes. | Open-air estimates miss steel, shielding, PCB copper, tolerance, adhesive thickness, and adjacent magnets. |
Source note: public supplier catalogs and device datasheets are appropriate for geometry, magnetization direction, and sensor threshold definitions. They are not enough to prove final field strength for a 1/16 x 1/32 diametric magnet inside a real assembly; that remains pending confirmation until the actual sensor, gap, housing, and magnet lot are measured together.
The checker uses repeatable baselines so the page can compare options, but procurement should replace these with the exact datasheet limits for the chosen part. For example, TI Hall switch literature distinguishes BOP, BRP, and hysteresis; Littelfuse reed resources specify sensitivity in ampere-turns; AKM magnetometer families publish measurement range by axis and mode.
| Sensor family | Real decision input | Tool baseline | Limitation to test |
|---|---|---|---|
| Digital Hall switch | Operate/release point, hysteresis, sample rate | 6 mT | A low-power switch can miss a short pulse if sampling rate and magnet speed are not checked. |
| Linear Hall sensor | Linear range, sensitivity, saturation limit | 12 mT | A stronger magnet can hurt accuracy if it pushes the output near saturation. |
| Reed switch | Operate ampere-turns, release ampere-turns, orientation | 10 mT | Reed behavior is geometry-sensitive; test pull-in/drop-out with the real magnet path. |
| Magnetometer / compass IC | Measurement range, offset calibration, hard/soft iron error | 1.5 mT | Nearby steel and permanent magnets can dominate the intended micro-magnet signal. |
Side-mounted digital Hall switches, very compact index points, low-inertia rotating targets, and assemblies where the magnet can be keyed.
Linear Hall position checks, reed switches, and magnetometers where calibration or gap control is available.
Large air gaps, unknown polarity orientation, high-temperature zones without grade validation, or safety-critical sensing without measurement data.
| Option | Best for | Tradeoff |
|---|---|---|
| Diametric cylinder magnet | Rotary index, side-mounted Hall sensing, compact angle cues | Orientation must be controlled during assembly |
| Axial cylinder magnet | End-on proximity, reed switch actuation, simple fixturing | Less useful when the sensor reads from the cylinder side |
| Ring magnet, diametric | Shaft-through rotary sensing and encoder targets | Higher cost and tighter concentricity requirements |
| Magnet pair or molded target | Higher field margin or custom pole pattern | More parts, tooling, and validation work |
Control three failure modes: wrong polarity orientation, undersized field margin, and supplier substitution without a drawing note. Mitigate them with keyed fixtures, measured sensor output at tolerance extremes, and an RFQ that explicitly says diametrically magnetized, not axially magnetized.

Premise
1/16 x 1/32 in diametric N52 magnet, 1 mm nominal gap
Process
Use the tool preset, keep the sensor on the curved side, and test operate/release through the plastic wall.
Result
Likely workable only if assembly tolerance stays tight and polarity is keyed.
Premise
Small cylinder target attached to a shaft or wheel
Process
Place the sensor tangent to the rotating magnet and scope the signal at speed.
Result
Diametric orientation gives a cleaner angular field transition than an axial end-read layout.
Premise
Buyer asks for a micro magnet across a 6 mm mechanical gap
Process
Run the gap check, compare against sensor threshold, then evaluate larger diameter or a magnetic target redesign.
Result
The micro alias size is usually undersized; geometry change is more credible than grade change.
These images are selected from the current product image set by diametric and encoder-related filenames. Use them to clarify RFQ intent when describing micro cylinders, disc stacks, or ring-style sensing targets.
Yes. It is a specific micro-size query inside the diametric magnet intent cluster, so this page keeps one canonical URL and answers that size explicitly here.
1/16 in is 1.5875 mm and 1/32 in is 0.79375 mm. Catalogs usually round this to about 1.59 mm diameter by 0.79 mm thickness.
The search intent is not meaningfully separate from diametric magnet selection. A dedicated page would duplicate the same orientation, gap, sensor, and sourcing guidance.
No. It is a first-pass screening tool for small sensor magnets. Final designs should use measured sensor response, gaussmeter data, or finite element analysis when risk is high.
Side-mounted Hall sensors are the most common fit. Reed switches and magnetometers can work, but they need threshold or calibration checks in the final geometry.
No. Higher grade can help, but the air gap, magnet volume, steel nearby, and sensor threshold often dominate small magnet results.
Polarity orientation. A diametric magnet must be keyed or verified so the sensor sees the intended side-to-side pole axis.
Send diameter, thickness, material grade, coating, magnetization direction, tolerance, operating temperature, sensor part number, nominal gap, and annual volume.
Yes, especially with side or center-reading magnetic angle sensors. Accuracy depends on concentricity, air gap, field strength, and calibration.
Choose axial when the sensor reads the magnet from the flat face or when simple end-on proximity switching is the main requirement.
Exact field at a given gap for a 1/16 x 1/32 magnet varies by material, coating, magnetizer, and fixture. Public catalog pages rarely prove final assembly performance.
Build one fixture at the intended gap, verify polarity, record sensor output across tolerance extremes, then freeze the magnet drawing.
Keep all size variants, including 1 16 x 1 32 diametric magnet, on this canonical URL. For sourcing, send the target sensor part, nominal gap, operating temperature, drawing, and required annual volume so the quote can be checked against the real sensing boundary.
