Product catalog summary

Axial Nonius Magnet Rings

Dimension Specifications: The rings have varying inner diameters (ØD1) ranging from 15.00 mm to 25.00 mm, with specific tolerances. The magnetic track inner diameters (ØD2) range from 16.00 mm to 29.10 mm. Outer diameters (ØD3) range from 29.00 mm to 44.50 mm. Insert thickness (E1) is consistently 0.60 mm, while total thickness (E2) varies slightly.
Magnetic Dimensions: The number of pole pairs on the Nonius track (N1) ranges from 31 to 63, with scanning reading diameters and pole widths specified. The master track (M1) has similar specifications with slight variations.
Material Characteristics: Remanence at 20°C is 190 mT, with a temperature coefficient of -0.19%/K.
Recommended Chip Position: Radial positions and mechanical air gaps are specified for optimal performance.
Thermal Data: Operating temperature range is -40 to 140°C. Specific iC-Haus chips are recommended for different models.
Precautions: External magnetic fields can affect functionality, and contact with magnetic clamps should be avoided.

Radial Nonius Magnet Rings

Dimension Specifications: Inner diameters (ØD1) range from 20 mm to 53.1 mm, with outer diameters (ØD2) from 24.50 mm to 59.6 mm. Heights (E) are specified with tolerances.
Magnetic Dimensions: The Nonius track (N1) and master track (M1) have specified numbers of pole pairs, scanning positions, and pole widths.
Material Characteristics: Similar to axial rings, with remanence at 190 mT and a temperature coefficient of -0.19%/K.
Recommended Chip Position: Radial positions and mechanical air gaps are specified.
Thermal Data: Operating temperature range is -40 to 140°C, with specific iC-Haus chips recommended.
Precautions: Similar to axial rings, external fields can affect functionality, and contact with magnetic clamps should be avoided.
