Hall Effect Sensor Magnets

Custom magnets for Hall effect position, proximity, speed, and switching sensors, with OEM support for geometry, tolerance, coating, and magnetic orientation.

Target Buyer:Best for OEM engineering teams selecting magnets around a fixed Hall IC, PCB position, and housing envelope.

Capability Highlights

  • Disc, cylinder, ring, block, and carrier-mounted magnet options
  • Axial, diametric, radial, and project-specific magnetization review
  • NdFeB, ferrite, SmCo, and AlNiCo selection based on temperature and signal target
  • Batch consistency controls for stable switching distance and sensor output

Typical Applications

  • BLDC motor position feedback
  • Door, lid, and limit detection
  • Fluid, level, and actuator position sensing
  • Consumer appliance and industrial control modules

Engineering Focus

  • Translate air gap, sensor sensitivity, and package constraints into a practical magnet geometry
  • Review magnetization direction against the Hall element axis and assembly orientation
  • Balance field strength, working temperature, coating, and cost targets before sample release
  • Define outgoing checks for dimensions, polarity orientation, and magnetic output by agreement

Key Evaluation Matrix

MetricTypical RangeWhy It Matters
Material selectionNdFeB, SmCo, ferrite, or AlNiCo by applicationMaterial choice controls signal strength, temperature stability, corrosion strategy, and cost.
Magnetization directionAxial, diametric, radial, or custom patternThe wrong orientation can pass dimensional checks while failing the sensor output window.
Dimensional toleranceProject-defined, tightened where the air gap is sensitiveSmall dimensional drift can change switching distance in compact sensor assemblies.

RFQ Checklist

  1. Sensor IC model or target operate/release point
  2. Air gap range, housing material, and available magnet envelope
  3. Drawing, tolerance, coating, and magnetization direction
  4. Working temperature, vibration, moisture, or corrosion exposure
  5. Prototype quantity, annual forecast, and packaging preference

Risk Controls

  • Switch point drift: Confirm sensor sensitivity, air gap stack-up, and magnet polarity before sample build.
  • Wrong pole orientation in assembly: Add polarity marks, fixture checks, and orientation notes to drawings and packaging.
  • Coating mismatch: Match coating to humidity, salt exposure, adhesive, and insert-molding conditions.

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.

Buyer FAQ

Can you help choose the magnet before our housing is final?

Yes. Share the sensor IC, air gap target, and space envelope so we can recommend a starting geometry for prototype review.

Do you support custom polarity or magnetization direction?

Yes. We can review axial, diametric, radial, and multipole requirements based on the drawing and application.
