Eclipse M17308/4/MSC Alnico Round Bar Magnet 4in

Product Description

The ECLIPSE M17308/4/MSC is an Alnico round bar magnet designed for industrial, scientific, and trade applications requiring stable magnetic performance across a wide temperature range. Measuring 4 inches in length and 0.125 inches in diameter, this compact cylindrical magnet delivers a maximum pull force of 0.35 pounds. Its Alnico alloy construction provides excellent temperature resistance, rated up to 1,022 degrees F, making it suitable for use in high-heat environments where conventional magnets would lose their properties. The smooth surface finish supports precise handling and integration into fixtures, sensors, and magnetic assemblies.

This bar magnet is used in a wide range of applications including magnetic circuit design, sensor positioning, lab instrumentation, and field service tooling. Its small-diameter, full-length Alnico construction makes it a practical choice for tight-clearance assemblies in electrical and instrumentation work. Technicians, engineers, and skilled tradespeople working with magnetic components in HVAC controls, motors, or custom fixtures will find this magnet suitable for both prototype and production use.

Key Features

• Alnico alloy construction supports maximum operating temperature of 1,022 degrees F
• Maximum pull force of 0.35 pounds in a slender 0.125-inch diameter profile
• 4-inch overall length for reach in narrow or deep assemblies
• Smooth surface finish for clean contact and easy integration
• Compact and lightweight at 0.1 pounds for easy handling and placement

Compatibility

Designed as a general-purpose Alnico round bar magnet suitable for magnetic circuit assemblies, sensor fixtures, instrumentation, and custom magnetic tooling applications.

Installation Notes

Handle Alnico magnets with care, as they are brittle and can chip or crack if dropped or struck against hard surfaces. Keep magnets away from sensitive electronic components, magnetic media, and pacemakers during handling. No special tools are required for most installations, but protective gloves are recommended when working near ferrous assemblies where snap-force contact is possible. Always verify magnetic orientation and pull force requirements against your specific assembly design before final installation.
