Applications:

We offer our highly popular 1/8″ diameter x 1/16″ thick disc magnets in N42SH grade, specially designed for high-temperature applications. With a maximum operating temperature of 302°F (150°C), N42SH magnets can withstand significantly more heat than standard N-grade magnets, which are limited to 176°F (80°C). These are ideal when you need a compact magnet that performs reliably in elevated temperatures.

Precision Sensing Systems:
Used in position sensing, speed detection, and encoder systems, typically working with Hall sensors in rotating or moving components.
High-Temperature Industrial Equipment:
Suitable for applications in demanding environments such as turbines, aerospace components, and energy systems, where reliable magnetic performance at elevated temperatures is required.
Tooling & Machining Fixtures:
Applied in precision machining for temporary positioning, holding, or alignment of small components without affecting accuracy.
Assembly & Component Retention:
Used for securing small parts during assembly or operation, improving efficiency and reducing the risk of component loss.
