Automotive Sensor Magnet Rotors

Custom molded magnet rotors for automotive position, angle, pedal, pump, and actuator sensing programs.

Target Buyer:Best for automotive sensor teams replacing glued sintered magnets or qualifying a new custom rotor.

Solution Highlights

Built around Hall, AMR, GMR, TMR, and custom magnetic sensing requirements
Chip-free bonded magnet construction for vibration-critical assemblies
RFQ support for sensing datum, pole design, and automotive validation needs

Common Use Cases

Throttle pedal modules
Steering angle sensors
Brake sensors
Pump feedback

Implementation Focus

Magnetic curve and sensor-air-gap alignment
Automotive thermal cycling, vibration, and inspection plan
Part traceability and PPAP-oriented documentation

Application Evaluation Matrix

Evaluation Metric	Typical Range	Buyer Relevance
Signal repeatability	Buyer-defined by sensor output and angle accuracy	Automotive sensing applications need repeatable magnetic output more than generic magnet strength claims.

RFQ Preparation Checklist

2D/3D drawing, material target, magnetic pattern, and sensing datum
Operating temperature, vibration, media exposure, and lifetime requirement
Sample quantity, tooling target, annual forecast, destination, and PPAP needs
Sensor IC family, air gap, curve target, and validation standard

Risk and Mitigation

Brittle sintered magnet carried into a vibration-critical assembly: Review bonded magnet material and molded geometry when chipping, cracking, or adhesive failure can affect functional safety.
Magnetic pattern accepted without measurable criteria: Define flux density, pole count, angle error, sensing radius, concentricity, and inspection method before sample tooling.

Buyer FAQ

What makes a sensor magnet rotor automotive-ready?

The rotor needs controlled magnetic pattern, datum-based concentricity, stable molded material, validation evidence, and documentation aligned with the buyer quality process.
