Eclipse 828 Alnico Pot Magnet 28.5 Lb 1.5 in Diameter

Product Description

The ECLIPSE 828 is a pot-style permanent magnet designed for holding, clamping, and fixturing applications in industrial and trade settings. Built around a Grade 5 Alnico core housed in a mild steel cup, it delivers an average pull force of 28.5 pounds (approximately 13 kg maximum) from a compact 1.5-inch diameter body. The red-finished steel shell focuses magnetic flux through the working face, concentrating holding force at the contact surface. At just 0.407 inches high, this low-profile magnet fits in tight mounting envelopes. It is commonly installed by machinists, fabricators, maintenance technicians, and fixture builders who need a reliable, screw-mounted magnetic hold point without complex hardware.

This magnet is well suited for light industrial fixturing, sensor mounting, tool holding, and assembly jig work where a compact, high-force-to-size ratio is required. The countersunk mounting hole accepts an M4 screw, allowing flush or recessed installation in metal frames, fixtures, and equipment panels. The Alnico 5 grade material supports a maximum operating temperature of 220 degrees C, making it appropriate for applications near heat sources where lower-grade magnets would lose performance over time.

Key Features

• 28.5 lb average pull force from a 1.5-inch diameter form factor
• Grade 5 Alnico core with 220 degrees C maximum operating temperature
• Mild steel pot construction focuses flux for maximum surface holding force
• 0.339-inch countersunk hole sized for M4 screw mounting
• Low-profile design at 0.407 inches overall height
• Red-finished shell for easy identification in multi-magnet assemblies

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial fixturing, sensor mounting brackets, and assembly tooling that specifies an M4-mount pot magnet with a 1.5-inch diameter footprint.

Installation Notes

Installation requires a standard M4 machine screw driven through the countersunk hole into the mating fixture or panel. Ensure the mating surface is clean, flat, and free of debris before seating the magnet, as surface contamination directly reduces effective pull force. Alnico magnets can be demagnetized by strong opposing fields or mechanical shock, so handle and store them away from large AC induction sources. No special tools or trade licensing are required for installation, but always confirm the mounting surface material is ferromagnetic before specifying this part.
