Product Description

Neodymium Magnets N42 Block 3/4 in x 1/4 in x 1/2 in

Neodymium Magnets N42 Block 3/4 in x 1/4 in x 1/2 in – Compact Rare Earth Magnet for Industrial Fixtures and Precision Assemblies

Engineered for precision assemblies and compact fixtures, this N42 block magnet offers high magnetic strength in a manageable size. Its rectangular profile provides a stable hold while allowing seamless integration into electronic housings, sensor fixtures, and magnetic clamping systems.

Key Features:

• Compact Rare Earth Magnet: Measures 0.75" (L) x 0.25" (W) x 0.5" (T), ideal for precision applications and tight spaces.
• High Strength N42 Grade: BrMax of 13,200 gauss, delivering a balance between power and cost-efficiency.
• Estimated Pull Force: Capable of holding up to 24 lbs under ideal conditions.
• Triple Coated: Nickel-Copper-Nickel plating ensures corrosion resistance for indoor, workshop, or controlled outdoor environments. Extended outdoor exposure should be minimized or the magnet sealed in a weather-resistant housing.
• Maximum Operating Temperature: Rated for continuous use up to 80°C (176°F). Higher temperatures may permanently reduce magnetic performance.
• Magnetized Through Thickness: North and south poles on the large faces for stable attachment and alignment.

Optimized for Industrial Fixtures and Precision Use

This N42 neodymium block magnet is ideal for use in electronic sensor mounts, small tool fixtures, clamping systems, and magnetic closures where reliability and strength are essential in a compact footprint. The high-grade N42 rating ensures dependable magnetic force while keeping the design practical for medium-load applications.

Common Applications:

• Magnetic tool holders and precision fixtures
• Sensor mounts and alignment jigs
• Small-scale magnetic clamping systems
• Cabinet closures and display fixtures
• Educational and scientific kits requiring strong rare earth magnets

Technical Specifications

Frequently Asked Questions (FAQ)

How can I mount this neodymium block magnet securely?
For flush or recessed installations, use high-strength epoxy or embed in non-magnetic housings. Avoid excessive impact to prevent chipping.

Is N42 strong enough for light industrial applications?
Yes, N42 grade provides excellent magnetic strength suitable for medium-load, space-conscious projects.

Can I use this magnet outdoors?
It can be used in covered or controlled outdoor environments, but for prolonged outdoor exposure, sealing within a weather-resistant housing is recommended.

What is the maximum temperature this magnet can safely handle?
N42 magnets can be used up to 80°C (176°F). Higher temperatures can reduce their magnetic strength permanently.

Is it safe near electronics?
Yes, but always confirm polarity and clearance before final integration, and be aware of magnetic field interactions with sensitive electronics.

Can I use this magnet outdoors?
Yes, in covered or controlled environments. For prolonged exposure to rain, humidity, or harsh weather, we recommend sealing the magnet within a weather-resistant housing to protect its magnetic performance and prevent corrosion.

Safety Note:

Neodymium magnets are extremely strong and brittle. They can chip or break if dropped or impacted. Handle with care, keep away from children and sensitive electronics, and avoid collisions with other magnets or metal objects.
