Buy N35 Neodymium Ring Magnet 20x5x5mm Online - Local Stock & Specs

Key Specifications & What They Mean

Understanding the main specs helps match the magnet to your application. The primary keyword "buy N35 neodymium ring magnet 20x5x5mm online" should guide you to pages that list these details.

• Grade - N35: Indicates the maximum energy product. N35 is a common, cost-effective grade for many hobby and light industrial uses.
• Dimensions: 20mm OD x 5mm ID x 5mm thick. Check whether OD/ID are nominal and the machining tolerance.
• Coating: Typical coatings are nickel-copper-nickel (Ni-Cu-Ni) or epoxy. Coating protects against corrosion; choose based on environment.
• Pull force / flux: Datasheet pull force is an approximate lab value; actual holding force depends on mating surface and air gap.

Specification Comparison

Accessories often bought with ring magnets include protective sleeves, retaining adhesives (e.g., anaerobic or epoxy rated for magnets), countersunk screws when mounting to metal, and ferrite backings to increase pull force. When you buy N35 neodymium ring magnet 20x5x5mm online, consider ordering a few extras to account for breakage or experimental layouts.

Compatibility & Application Guidance

N35 neodymium ring magnet 20x5x5mm is widely compatible with small brushless motors, sensor targets (e.g., hall-effect rotary sensors), magnetic couplings and retaining clips. For sensor use, ensure magnet thickness and pole orientation meet sensor datasheet specifications.

Mounting and Safety Tips

• Avoid pinching: neodymium magnets are brittle and can shatter; handle with care and wear eye protection when manipulating multiples.
• Temperature limits: N35 loses magnetisation above the rated maximum temperature (check datasheet); for heated environments choose a high-temperature grade if needed.
• Corrosion protection: use coated magnets in humid or coastal South African conditions to reduce rust risk.

Specification Callouts & Bundles

When you view product listings, look for clear callouts: grade (N35), exact OD/ID/thickness, coating, and a stated tolerance. Consider these accessory bundles when you buy N35 neodymium ring magnet 20x5x5mm online:

• Magnet pack: 5 or 10 pieces for prototyping and spare parts.
• Mounting kit: small countersunk screws, washers, and epoxy adhesive.
• Sensor starter: hall sensor, magnet, and breakout board for encoder experiments.
