Radial Encoder Magnets for AS5600 AS5040 AS5045 – 10pcs

Radial Magnetizing Encoder Magnets for AS5600, AS5040, AS5045 & More

These precision radial magnetizing encoder magnets are purpose-built for use with popular magnetic encoder ICs including the AS5600, AS5040, AS5045, AS5047, AS5048, AS5145, and AS5147. Sold in a convenient pack of 10, each compact magnet (6mm × 2mm / 0.6cm × 0.2cm) delivers reliable, consistent magnetic field strength essential for accurate angular position sensing in robotics, motor control, automation, and hobbyist electronics projects.

Crafted from high-quality magnetic material with a diametrically (radially) magnetized orientation, these magnets are designed to sit directly on a rotating shaft and work in perfect alignment with the encoder sensor below. Their small footprint makes them an ideal fit for miniature assemblies, servo motors, brushless motor feedback systems, and compact mechatronic builds.

Why Radial Magnetization Matters

Unlike axially magnetized magnets, radially (diametrically) magnetized encoder magnets produce a rotating magnetic field vector as the shaft turns. This is precisely what Hall-effect encoder ICs like the AS5600 require to calculate accurate absolute angle positions up to 360°. Using the correct magnet type ensures maximum accuracy, minimal signal noise, and full compatibility with your encoder chip's specifications.

Frequently Asked Questions

Q: Are these encoder magnets compatible with the AS5600 and AS5048 ICs?

A: Yes. These radial magnetizing encoder magnets are specifically designed for use with AS5600, AS5040, AS5045, AS5047, AS5048, AS5145, AS5147, and similar diametric Hall-effect magnetic encoder ICs. Their 6mm × 2mm dimensions and radial magnetization match the recommended magnet specifications for these sensors.

Q: What does "radial" or "diametric" magnetization mean for encoder magnets?

A: Radial (diametric) magnetization means the North and South poles are oriented across the diameter of the magnet disk rather than through its thickness. When the magnet rotates on a shaft above the encoder IC, this orientation creates a predictable rotating magnetic field that the IC uses to calculate precise angular position — which is exactly what encoders like the AS5600 are designed to read.

Q: How many magnets are included, and what size are they?

A: Each pack includes 10 magnets, each measuring 6mm in diameter and 2mm in thickness. This makes them compact enough for use in small motors, compact robotics joints, and miniature encoder assemblies.

Q: Can I use these magnets for robotics or 3D printer builds?

A: Absolutely. These encoder magnets are popular in DIY robotics, 3D printer axis feedback systems, servo motor control, and any project requiring precise rotary position sensing. Their small size and consistent field strength make them a reliable choice for both prototyping and production builds.
