MGT Cylinder Magnet 6x15mm for Electronic Projects - Buy in South Africa

Overview

The MGT cylinder magnet 6x15mm is a compact neodymium (NdFeB) cylinder magnet commonly used in reed sensor triggers, rotary encoders, small motor assemblies and magnetic mounts for electronics projects. Its 6 mm diameter and 15 mm length provide a strong magnetic field in a small footprint, ideal for hobbyists, students and engineers working on robotics and prototyping.

Why choose a 6x15mm cylinder magnet

• Compact form factor suits tight enclosures and PCB-adjacent placements.
• Good field strength for reliable switching of reed sensors and hall-effect sensors.
• Straightforward to mount with adhesive, countersunk screws or press-fit arrangements.

Availability and local considerations

If you need immediate stock for a class project or prototype, check local availability and branch pickup options. Communica maintains a national footprint with a head office/warehouse in Samrand and additional branches; verify stock levels and lead times before ordering.

Compatibility and common use-cases

The MGT cylinder magnet 6x15mm is compatible with many sensor types used in maker and educational projects. Typical pairings include reed switches, hall-effect sensors (digital and analog), rotary encoder magnets and as a detent magnet for small motors or latching mechanisms.

If you are assembling development kits or teaching modules, consider buying in small packs or multipacks to keep spares on hand for student labs.

Selection criteria and specification callouts

How to choose the right 6x15mm cylinder magnet

• Grade: higher N-number (e.g., N52) gives stronger fields but may be more brittle and costlier.
• Coating: Ni-Cu-Ni is common to reduce corrosion; check if the application is humid or chemical-exposed.
• Temperature rating: ensure the operating temperature of your device stays below the magnet's rated maximum.
• Mounting method: adhesives, set screws or press-fit - consider magnetic forces when selecting fixings.

Specification callout

When comparing listings, look for explicit values for pull force (in kgf or N), magnetisation direction (axial vs radial), coating type and temperature rating. If the product page lacks these, request the datasheet or compare similar SKUs via the Shop by Brand index to find technical specs.

Compatibility guidance and accessory bundles

Common accessories to buy with a 6x15mm magnet:

• Hall-effect sensors (digital latch-style or analog linear sensors)
• Reed switches and sensor housings for through-panel mounting
• Adhesives (epoxy) or small countersunk steel plates for secure mounting

A sample accessory bundle for a student lab: 10 x MGT 6x15mm magnets + 10 x digital hall sensors + adhesive - this keeps per-student cost predictable and reduces downtime for experiments.

Practical examples and brief calculations

Example: triggering a digital hall-effect sensor with the 6x15mm magnet. If the sensor requires a flux density of ~5-20 mT at the switching point, place the magnet so its axis aligns with the sensor face. Empirical testing is common - start at 5 mm separation and adjust. For safety when estimating pull forces, assume a 30-50% reduction if the magnet is pulling through non-flat surfaces or with air gaps.

Cost and procurement note (South Africa): single magnet units can range modestly in price; for classroom purchases request a quote and VAT invoice through Communica's account services and check branch pickup at Samrand to save shipping time.
