Product Description
Neodymium Magnets N45 2 in x 1/8 in Disc
Neodymium Magnets N45 2 in x 1/8 in Disc – Large Flat Rare Earth Magnet for Sensor Arrays and Instrument Mounting
Engineered for large-surface installations and low-profile requirements, this N45 neodymium disc magnet 2 inch delivers a balance of strength, affordability, and versatility. Its thin build and expansive surface make it ideal for flush mounting in sensor housings, scientific kits, and magnetic closure systems.
Key Features:
- Large Flat Rare Earth Magnet: 2-inch diameter provides extensive surface contact while the 1/8-inch thickness keeps the profile low.
- High Strength N45 Grade: Delivers BrMax of 13,800 gauss, a reliable middle ground between affordability and performance.
- Estimated Pull Force: Capable of holding up to 29 lbs under ideal conditions.
- Triple Coated: Nickel-Copper-Nickel plating ensures excellent durability and corrosion resistance.
- Magnetized Through Thickness: North and south poles on the flat surfaces, ideal for surface contact and alignment.
Optimized for Precision Projects and Flush Mounting
This thin large magnet for instrument housings is ideal for use in sensor arrays, flush-panel installations, or lightweight assemblies where maximum contact and minimal height are important. The wide diameter offers stability, while the N45 grade provides strong magnetic force without the cost of N52 magnets.
Whether you're designing electronic sensor systems, developing scientific kits, or building magnetic closures for products or packaging, this neodymium magnet for sensor arrays offers an optimal mix of size, strength, and reliability.
Common Applications:
- Flush-mounted magnetic closures for electronics or cabinets
- Sensor arrays and alignment systems
- Precision instrument housings and control panels
- Low-profile attachment points in packaging or retail fixtures
- Educational tools and science demonstration kits

Frequently Asked Questions (FAQ)
How should I mount this thin large magnet for instrument housings?
Use epoxy adhesive or secure it in a recessed pocket for flush mounting. Avoid excessive torque or impact to prevent chipping.
Is N45 strong enough for moderate industrial use?
Yes. While not as strong as N52, N45 still delivers powerful magnetic force at a lower cost, making it ideal for medium-load applications where size and profile are key.
Can this N45 neodymium disc magnet 2 inch be used outdoors?
It can be used in covered or controlled environments. For extended outdoor use, consider sealing or pairing it with a weather-resistant enclosure.
Is this safe to use with electronics or sensors?
Yes, but keep clearances and magnetic field interactions in mind. Always test alignment and polarity before full integration into electronics or sensor arrays.
Reliable Magnetic Performance in a Low-Profile Design
From sensor arrays to magnetic enclosures, this N45 neodymium disc magnet 2 inch offers consistent strength and a form factor that makes it ideal for space-conscious applications. Use this large flat rare earth magnet in light industrial, scientific, or product design environments where precision and pull strength are high-priority.
