Application Evaluation Matrix

Evaluation Metric	Typical Range	Buyer Relevance
Reliability	>1M operating cycles	Protects field reliability and warranty performance
Thermal Cycle Flux Stability	Project-defined allowable drift	Prevents signal or torque behavior drift across seasonal extremes
Process Capability (Critical Features)	Typically Cpk >= 1.33 for agreed CTQs	Improves consistency across lots and reduces line disruption risk

RFQ Preparation Checklist

Target annual volume
Operating temperature profile
Validation standards (PPAP / DV / PV)
Critical dimensions and magnetic acceptance thresholds
Warranty/reliability expectations and failure definitions

Risk and Mitigation

Flux drift in thermal cycling: Material-grade selection with thermal aging verification
Retention failure under vibration and shock: Retention method validation with representative DV/PV load profiles
Program delays from unclear documentation scope: Early alignment on PPAP/document package responsibility and timing

Solution Selection Playbook

Treat solution selection as a controlled engineering decision, not a catalog pick. Align material limits, mechanical interfaces, and validation evidence before commercial approval so buyer, R&D, and supplier teams are using the same acceptance language.

Define pass/fail thresholds for Reliability at prototype and pilot stages.
Verify implementation assumptions around Magnet retention under vibration + Corrosion resistance in road environments in your real operating environment.
Place Target annual volume, Operating temperature profile, Validation standards (PPAP / DV / PV) in the initial RFQ pack so supplier quotes are comparable.
Require mitigation evidence for Flux drift in thermal cycling before releasing production intent.
