How to Use These Buyer Guides

This library is built for procurement and engineering alignment, not general marketing reading. Each article includes decision criteria, risk controls, and practical actions you can reuse in real RFQ and validation workflows.

  1. Start from selection guides to narrow architecture choices.
  2. Use RFQ checklists to reduce back-and-forth with suppliers.
  3. Bring the same acceptance criteria into sample and mass-production gates.

Reading Order by Project Stage

Read articles in decision order so your team moves from magnet selection to RFQ quality and then to customization governance without missing critical handoff details.

Project StageRecommended ArticleDecision Output
1. Select the magnetic architectureMagnetization Direction Selection for Sensor MagnetsPole direction, sensor axis, air-gap, and magnetization notes for the drawing.
2. Prepare the RFQ packageSensor Magnet RFQ Checklist for OEM BuyersSupplier-ready RFQ fields, quote comparison scorecard, cost drivers, and handoff checklist.
3. Approve samples and repeat lotsSensor Magnet Failure Modes and Incoming Inspection PlanRisk-based inspection gates, report structure, and corrective-action questions.

You can also filter by buyer intent in our product engineering, factory quality, and buyer guides categories.
