Flat countersunk pot magnet D19.1 mm H7.5 mm with through hole, holding force 30 N – TECWERK

The flat countersunk pot magnet D19.1 H7.5 is a compact AlNiCo 500 cup magnet designed for secure, high-temperature fastening in jigs, fixtures and light assembly tasks

• AlNiCo 500 alloy for high-temperature use
• Countersunk through hole, bore Ø 3.7 mm
• Compact Ø 19.1 mm × H 7.5 mm design
• Holding force 30 N for secure attachment

High-temperature stability for reliable fixing

The core advantage of this component is its AlNiCo 500 construction, which provides stable magnetic properties at elevated temperatures up to 450 °C. For applications involving heat or proximity to baking processes, the magnet maintains performance where many ferrite or rare-earth magnets would demagnetise. The 30 N retention force supplies a predictable, repeatable hold for light securing and positioning tasks, making the component suitable for small fixtures and temporary jigs in production environments. This section focuses on measurable performance and explains why material choice matters for thermal resilience.

Small footprint for precise positioning in assemblies

With an external diameter of Ø 19.1 mm and a height of 7.5 mm, the unit occupies minimal space while offering a flat contact face for reliable engagement. The Ø 3.7 mm central bore with countersink permits recessed screw mounting so fasteners sit flush, reducing profile interference and improving repeatability when used in alignment or locating applications. The compact geometry supports integration into tight assemblies and tool stations where minimal disturbance of adjacent components is important. Practical benefits include easier handling in confined jigs and stable placement during repetitive operations.

Practical mounting and production considerations

The magnet is supplied in packaging unit: 10 and is executed with through hole and countersink to suit conventional countersunk screw fixation. During component manufacture, the magnet’s coating processes can be exposed to a baking stage up to 200 °C, as indicated by production parameters; this is relevant for bespoke surface treatments or assembly steps that involve elevated temperatures. For installation, select a countersunk screw that matches the 3.7 mm bore and the desired clamping torque, and avoid impacts that could impair the magnet’s seating. The combination of compact form and a recessed fixing point streamlines assembly workflows without compromising hold.

FAQ

What material is the magnet made from and why does it matter?
The magnet is produced from AlNiCo 500, chosen for its thermal stability and predictable magnetic performance at elevated temperatures, which makes the flat countersunk pot magnet D19.1 H7.5 suitable for heated environments.

What holding capacity can be expected from this cup magnet?
The device provides a holding force of 30 N, offering a reliable grip for light securing and positioning tasks in fixtures and small assemblies using the TECWERK flat countersunk pot magnet (SKU 4000832270NW).

How is the magnet mounted in an application?
Mounting is via the central Ø 3.7 mm through hole with countersink so a countersunk screw sits flush, ensuring a low profile and repeatable fixing when used in jigs or tooling.

Are there any temperature limits for use or processing?
The magnet maintains magnetic properties up to 450 °C; manufacturing or coating processes may include a baking stage up to 200 °C, which should be considered during component processing.
