Product Description
N52 Neodymium Ring Magnet – 0.365" OD x 0.2" ID x 0.25" Thick
High-Performance Industrial Grade Rare Earth Magnet This premium N52 Neodymium Ring Magnet (SKU: NR003-52NM) represents the pinnacle of magnetic energy density. Sintered from high-grade Neodymium-Iron-Boron (NdFeB), this ring magnet provides a concentrated magnetic field ideal for precision engineering and high-torque applications. With a Grade N52 rating, it offers significantly higher flux density and coercive force than standard N35 or ceramic alternatives.

Engineered for Versatility: Whether you are sourcing for aerospace components, medical device manufacturing, or advanced robotics, this rare earth ring magnet delivers consistent performance. The center hole allows for mechanical fastening using non-magnetic screws, making it a favorite for:
-
Magnetic Sensors & Hall Effect Switches: Reliable triggering for industrial automation.
-
Acoustic Equipment: Precision components for high-end speakers and microphones.
-
Renewable Energy: Small-scale wind turbine generators and motor assemblies.
-
Scientific Research: Perfect for physics labs requiring high-flux density in a small footprint.
Handling & Safety Compliance: Due to the brittle nature of sintered neodymium and the high pull force of Grade N52, professional handling is required.
-
Collision Prevention: These magnets should be slid apart rather than pulled; sudden impacts can lead to shattering.
-
Thermal Limits: Maximum operating temperature is 176°F (80°C).
-
Safety: Keep away from pacemakers, credit cards with magnetic strips, and small children.
