ProductsNon-Magnetic Technology
High-precision testing with minimal magnetic interference
As electronic devices become more advanced and compact, the demand for precision testing continues to grow—especially when it comes to components affected by magnetic fields. Traditional testing methods often fall short in these scenarios. That’s where Seiken’s non-magnetic technology comes in.
By combining carefully selected non-magnetic materials with advanced manufacturing techniques, we deliver probe solutions that minimize magnetic interference and ensure accurate, reliable measurements. Our lineup also includes specialized features such as non-magnetic alloys that resist solder adhesion, and narrow-pitch support using next-generation Kelvin technology—ideal for challenging inspection environments.
Whether you’re testing electronic compasses, Hall ICs, or MR/MI sensors, our non-magnetic probes offer some of the most reliable solutions available in Japan. If you’re looking to minimize the effects of magnetic fields and achieve the highest level of test accuracy, our non-magnetic probes are the ideal choice.
Key Features & Advantages
01 Top-class low magnetization properties
Through material selection and precision processing, we achieve one of the lowest magnetization levels in the industry—greatly reducing magnetic interference and enabling high-accuracy testing.
02 Non-magnetic technology design
The probe tips are made from non-magnetic precious metal alloys, ensuring stable contact and minimal magnetic influence. These materials also provide excellent connectivity with lead-free solder bumps and Sn-plated terminals.
03 Flexible probe layouts
Enjoy all the benefits of spring probes while adapting to area arrays and custom pin configurations. Our solutions allow for highly flexible test setups tailored to your design.
04 Adaptable to fine-pitch, short probes
- Minimum probe diameter: Φ90μm
- Minimum pitch: 150μm
- Shortest overall length: 3.25mm (for 300μm pitch)
05 Non-magnetic customization available for catalog products
Many of our catalog-listed probes can be customized with non-magnetic materials. We’re happy to accommodate special requests.
*Please note that production may require additional lead time.
