• Magnet Grade: N52 
• Pull Force: Approx. 3.4 lbs 
• Magnetization: Axially magnetized (Poles on the flat circular faces)

Material Description:

Our 10mm x 2mm N52 black epoxy coated disc magnets provide a high-performance, weather-resistant fastening solution for projects exposed to high humidity, moisture, or light outdoor conditions. Unlike standard triple-layer nickel plating which can oxidize over time in damp environments, the continuous black epoxy resin shell forms an airtight shield over the rare-earth core. The low-profile 2mm thickness makes it ideal for embedding into shallow routed pockets, cabinetry, or molded plastics using high-strength epoxy or acrylic adhesives. The matte black finish also provides a stealthy, professional look for high-end retail displays and consumer goods.

Handling Advice: DANGER: Low-profile N52 rare earth discs require careful handling. Sintered neodymium is inherently brittle like ceramic. Striking magnets together or hitting steel surfaces with high velocity can cause the thin discs to chip, fracture, or breach the protective epoxy layer. To maintain maximum corrosion resistance and prolong product life, always separate individual pieces by sliding them off the stack rather than pulling them apart vertically, and avoid high-impact collisions during assembly.

Warnings and Safety Information:

• Pinch Hazard: Strong enough to cause sharp skin pinches or small blood blisters if handled carelessly in groups.
• Fragility Hazard: Slim profile is brittle. Prevent high-impact collisions to avoid chipping the core or the coating.
• CHOKING HAZARD: Keep securely stored and out of reach of children and pets.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants at all times.

Applications:

• Moisture-resistant hidden latches for marine cabinetry, outdoor enclosures, and humidor box lids
• Concealed alignment closures for premium waterproof outerwear, tactical gear, and technical apparel
• Discreet flush-mount attachments for outdoor signage, vehicle banners, and exhibition presentation frames
• High-efficiency sensory triggers, reed switch activations, and low-clearance Hall-effect arrays in damp environments
• Shallow inlay mounting points for thin 3D-printed outdoor equipment housing panels and battery doors
