Custom Magnetic Assemblies

Factory support for magnets integrated into carriers, plastic housings, metal parts, floats, shafts, and sensor modules where assembly orientation matters.

Target Buyer:Best for OEM buyers who want to reduce internal assembly risk by sourcing a magnet as a controlled subassembly.

Custom Magnetic Assemblies reference visual for buyer-side RFQ and sample validation.

Capability Highlights

  • Magnet plus carrier, insert, bracket, cup, float, or rotor support
  • Assembly orientation, polarity, adhesive, and fixture review
  • Prototype-to-production workflow for OEM programs
  • Packaging and documentation aligned to buyer inspection needs

Typical Applications

  • Sensor trigger assemblies
  • Float and level sensor magnets
  • Rotary encoder carriers
  • Magnetic latches and proximity modules

Engineering Focus

  • Translate the magnet drawing and carrier drawing into a controlled assembly process
  • Review adhesive, overmolding, press-fit, ultrasonic welding, or mechanical retention options
  • Define polarity, datum, and inspection controls before pilot production
  • Align packaging so parts arrive ready for buyer-side line use

Key Evaluation Matrix

MetricTypical RangeWhy It Matters
Assembly retention methodAdhesive, press-fit, overmold, fixture, or mechanical lockRetention choice affects durability, magnetic alignment, tooling, and unit cost.
Polarity datumDrawing-defined reference surface or fixture featureSubassemblies fail when the magnet is physically present but magnetically misaligned.
Inspection scopeDimensions, polarity, pull force, or magnetic output by agreementClear inspection scope prevents quote ambiguity and acceptance disputes.

RFQ Checklist

  1. Assembly drawing, exploded view, or CAD package
  2. Magnet material, coating, magnetization, and polarity datum
  3. Carrier material, retention method, and assembly environment
  4. Critical-to-quality dimensions, magnetic output points, and inspection needs
  5. Prototype quantity, pilot quantity, annual forecast, and shipping destination

Risk Controls

  • Magnet shifts during assembly: Review fixture design, adhesive cure, carrier tolerance, and retention method.
  • Assembly looks correct but fails magnetic orientation: Add polarity checks and magnetic datum notes to the work instruction.
  • Tooling decisions made too early: Use prototype samples to freeze geometry before committing to production tooling.

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 a magnet already assembled into a housing?

Yes. Send the assembly drawing, material details, magnetic datum, and expected inspection points.

Can you support OEM branding or custom packaging?

Yes. OEM packaging and labeling can be discussed as part of the RFQ and production plan.
