Diametric Sensor Magnets

Diametrically magnetized cylinders, discs, and rings for rotary angle sensing, level sensors, and compact magnetic position systems.

Target Buyer:Best for engineers using the rotating field of a diametric magnet as the sensing reference.

Capability Highlights

  • Diametric cylinders, discs, rods, and ring options
  • Magnetization direction review for angle and rotary sensing
  • Material and coating selection around temperature, corrosion, and bonding
  • Prototype support for air gap and sensor linearity evaluation

Typical Applications

  • Rotary angle sensing
  • Liquid level and float sensors
  • Knob, valve, and actuator position feedback
  • Compact Hall sensor modules

Engineering Focus

  • Confirm diametric direction, mechanical datum, and sensor axis before sample production
  • Review magnet length-to-diameter ratio against signal shape and assembly envelope
  • Control coating and bonding compatibility where the magnet is inserted into a carrier
  • Define marking or packaging method so the diametric axis is clear during assembly

Key Evaluation Matrix

MetricTypical RangeWhy It Matters
Diametric axis controlMarked or fixture-controlled by agreementAngle-sensing assemblies depend on consistent magnetic axis orientation.
Geometry ratioProject-defined diameter and lengthGeometry affects field shape, usable air gap, and sensor output smoothness.
Temperature stabilityMaterial selected by operating environmentMagnetic output can shift across temperature if material selection is wrong.

RFQ Checklist

  1. Drawing or target diameter, length, and tolerance
  2. Required diametric direction mark or assembly reference
  3. Sensor IC, air gap, rotation angle, and expected output behavior
  4. Material, coating, working temperature, and bonding or insert method
  5. Prototype quantity and annual production forecast

Risk Controls

  • Axis mark is unclear in production: Define marking, tray orientation, or assembly fixture references in the RFQ package.
  • Insufficient signal at the sensor: Validate air gap, magnet size, and sensor sensitivity during prototype testing.
  • Bonding or coating failure: Confirm adhesive, coating, carrier material, and process temperature before release.

Validation Boundary Before Drawing Freeze

Field proof

Use gaussmeter mapping as a screening step, then confirm sensor output at the assembled air gap.

Environment proof

Review temperature, corrosion, vibration, adjacent metal, coating limits, and demagnetization margin.

Document proof

Request inspection records, C of C, RoHS/REACH-style files, or PPAP-ready evidence only when the project requires it.

Automotive, medical, aerospace, and other high-reliability programs should treat page data as sourcing guidance. Final approval depends on buyer-specific testing, documentation scope, and application validation.

Product and Application References

Matched product visuals selected from the current sensor magnet image library by filename and topic fit. Use them as RFQ discussion references, not as final drawing approval.

Buyer FAQ

Can you quote diametric magnets from a drawing?

Yes. Please include the diametric axis, tolerance, material, coating, and any marking requirement.

Can you support angle sensor prototypes?

Yes. We can help review candidate sizes and provide samples for buyer-side validation.
