Eclipse N303 Neodymium Disc Magnet 4 Lb Pull Force

Product Description

The ECLIPSE N303 is a neodymium rare earth disc magnet designed for applications requiring strong magnetic pull in a compact form factor. Measuring 0.375 inches in diameter and 0.125 inches in height, this cylindrical disc delivers a maximum pull force of 4 pounds. Constructed from grade N38SH neodymium material, it is rated for continuous use up to 302 degrees F. HVAC technicians, electricians, and industrial maintenance professionals commonly use rare earth disc magnets for sensor positioning, component holding, reed switch actuation, and panel assembly tasks.

The N303 is suited for light-duty trade and industrial applications where a small, high-strength magnet is needed. Its compact disc profile fits into tight spaces common in control panel assemblies, motor housings, and diagnostic tool setups. The N38SH grade designation indicates a high-coercivity formulation, making it more resistant to demagnetization at elevated temperatures compared to standard neodymium grades. This makes it a practical choice for service environments where ambient temperatures can approach the rated limit.

Key Features

• Neodymium rare earth construction, grade N38SH for elevated-temperature resistance
• Maximum pull force of 4 pounds in a 0.375-inch diameter disc form
• Rated for maximum operating temperature of 302 degrees F
• Compact 0.125-inch height fits restricted-clearance installation points
• Disc cylinder shape supports flush-mount and surface-contact applications

Compatibility

Designed as a general-purpose neodymium disc magnet for trade and industrial use where a compact rare earth magnet with a 0.375-inch diameter and 4 lb pull force rating is specified.

Installation Notes

Neodymium magnets should be handled with care to avoid pinch injuries during placement near ferrous surfaces or other magnets. Keep away from sensitive electronics, magnetic storage media, and pacemakers during handling. When used in HVAC or electrical panel applications, de-energize equipment before accessing the installation area per applicable NEC or manufacturer guidelines. Avoid exposing the magnet to temperatures exceeding the 302 degrees F rating to prevent permanent loss of magnetic strength.
