Precision magnets for medical sensing, actuation, and positioning applications — from endoscope drives and infusion pump encoders to bio-magnetic separation and laboratory instruments.
Medical Device Sensor Magnets application reference selected from the sensor magnet image library.
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Sterilization compatibility | Autoclave 134°C / EtO / Gamma 25-50 kGy | NdFeB standard grades may demagnetize during autoclave. SmCo or high-temp NdFeB grades are required for steam sterilization. |
| Coating biocompatibility | Parylene C, PTFE, gold, medical epoxy | Standard nickel plating may cause allergic reactions. Medical applications often require ISO 10993 tested coatings. |
| Dimensional tolerance | ±0.02 mm to ±0.05 mm | Micro-gap medical sensor assemblies require tighter tolerance than industrial applications. |

Standard NdFeB grades (N-series, max 80°C) cannot survive autoclave at 134°C. High-temperature grades (SH at 150°C, UH at 180°C) may work with margin analysis. For repeated autoclave cycles, SmCo is the safer choice.
We provide magnets with coatings from suppliers who hold ISO 10993 certifications. The biocompatibility testing itself is typically performed by the device manufacturer as part of their regulatory submission.
Yes. We can provide lot-coded packaging, material certificates, coating batch records, and magnetic inspection reports that trace each shipment back to raw material batch and production date.
