Custom molded magnet rotors for automotive position, angle, pedal, pump, and actuator sensing programs.
Automotive Sensor Magnet Rotors is most relevant when best for automotive sensor teams replacing glued sintered magnets or qualifying a new custom rotor. Typical solution programs include Throttle pedal modules, Steering angle sensors, and Brake sensors, so the early review should confirm magnetic curve and sensor-air-gap alignment.
Before sample tooling, align on 2D/3D drawing, material target, magnetic pattern, and sensing datum and operating temperature, vibration, media exposure, and lifetime requirement. The first acceptance check is signal repeatability (Buyer-defined by sensor output and angle accuracy), because automotive sensing applications need repeatable magnetic output more than generic magnet strength claims.
The main risk is brittle sintered magnet carried into a vibration-critical assembly; control it by review bonded magnet material and molded geometry when chipping, cracking, or adhesive failure can affect functional safety. Also review validation handoff and magnetic pattern accepted without measurable criteria before moving from prototypes to repeat production.
| 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. |
| Validation handoff | Operating temperature, vibration, media exposure, and lifetime requirement | It connects Automotive Sensor Magnet Rotors design intent to sample approval, lot inspection, and production sourcing decisions. |
The rotor needs controlled magnetic pattern, datum-based concentricity, stable molded material, validation evidence, and documentation aligned with the buyer quality process.
Include 2D/3D drawing, material target, magnetic pattern, and sensing datum, operating temperature, vibration, media exposure, and lifetime requirement, and sample quantity, tooling target, annual forecast, destination, and PPAP needs. If the part is tied to automotive or safety-critical sensing, also include PPAP, traceability, and magnetic test expectations.
