Eclipse E823 Alnico Button Magnet 1 in 7.5 Lb Pull Force

Product Description

The ECLIPSE E823 is a Grade 5 Alnico button magnet designed for holding, retrieval, and fixture applications where a compact, high-temperature-resistant magnet is required. It measures 1 inch in diameter and 0.625 inches in height, with a 3/16-inch center hole that allows for through-bolt or screw mounting. The magnet delivers a maximum pull force of 7.5 pounds (3.4 kg), making it suitable for moderate-duty clamping and positioning tasks. Constructed from Alnico 5 material, it maintains magnetic performance at elevated temperatures up to 550 degrees C, a key advantage over ceramic or neodymium alternatives in high-heat environments.

The E823 button magnet is used in manufacturing, maintenance, and trade service applications where a small, reliable permanent magnet is needed. Typical uses include sensor mounting, tooling fixtures, panel holding, and retrieval of ferrous components in confined spaces. Its through-hole design makes it straightforward to integrate into custom assemblies or mount to non-magnetic surfaces using standard fasteners. The compact button profile fits where larger magnet assemblies cannot.

Key Features

• Maximum pull force of 7.5 lb (3.4 kg) for moderate-duty holding and clamping
• Grade 5 Alnico 5 construction rated for continuous use up to 550 degrees C
• 1-inch diameter with 3/16-inch center hole for through-bolt mounting
• 0.625-inch overall height with 11/32-inch gap width
• Compact button form factor for space-constrained fixture and sensor applications
• Weighs 0.16 pounds — lightweight for easy handling and installation

Compatibility

Designed as a standard-format Alnico button magnet suitable for general-purpose holding, mounting, and retrieval applications across industrial, HVAC, and trade service settings where a 1-inch diameter through-hole magnet is specified.

Installation Notes

Mount using a fastener through the 3/16-inch center hole; ensure the mating ferrous surface is clean and flat to achieve rated pull force. Keep the magnet away from sensitive electronic components, magnetic storage media, and precision instruments during handling and installation. Alnico magnets can be demagnetized by strong opposing magnetic fields — avoid contact with high-powered magnets during service. No special tools are required for standard mounting.
