Button magnet Ø25.4 x H15.9 mm – split contact surface, holding force 34 N (TECWERK)

Button magnet Ø25.4 x H15.9 mm – split contact surface and through‑hole for fast mounting

• Split contact surface for even force distribution
• Holding force 34 N for secure small-part clamping
• AlNiCo 500 alloy tolerates high operating temperatures
• Through-hole Ø4.8 mm for screw mounting

Secure clamping with compact footprint

The button magnet offers focused clamping power in a small package: with a holding force of 34 N and a diameter of Ø25.4 mm, the unit is designed for reliable retention of small components in assembly, jigs and fixtures. The split contact surface reduces shifting under lateral loads by evening out contact pressure, which is particularly useful where precise alignment matters. The integrated through‑hole (Ø4.8 mm) allows straightforward mechanical fastening for permanent or semi‑permanent installations, combining magnetic fixing with a screw or bolt for enhanced security.

Reliable performance at elevated temperatures

Constructed from AlNiCo 500, this magnetic element maintains magnetic stability where many permanent magnets lose strength. The material choice delivers maximum operating temperature 450 °C, making the magnet suitable for applications exposed to elevated heat, such as heat‑treatment jigs or fixtures near ovens. A coating bake temperature of 200 °C is compatible with common lacquer processes, permitting secondary surface finishes without compromising magnetic performance.

Simple integration into workshop processes

The compact height of H15.9 mm and the small diameter keep the magnet unobtrusive while enabling precise placement in toolmaking and small‑parts handling. The through‑hole permits repeatable mounting, facilitating modular fixture design and quick replacement during maintenance. The design supports both permanent mounting and temporary clamping solutions where a mechanical backup is required for safety or positioning accuracy.

Practical benefits for production and assembly

Supplied as a single unit in a practical packaging size, the component suits small runs and prototyping as well as series production where consistent magnetic behaviour is required. The use of AlNiCo 500 ensures predictable performance over temperature cycles, while the split contact surface minimises lateral slip, reducing rework and downtime. The product is therefore attractive for workshops, toolrooms and light industrial assembly lines seeking compact, heat‑resistant magnetic clamps.
