2.6.6. BLMX Tolerances

With the forcer aligned as in Figure 2-9, the air gap in the magnet track is 1.0 mm (0.040 in) on either
side of the forcer coil. The straightness can deviate left or right to ±0.51 mm (0.020 in) from the
centerline. For example, a deviation can result in an 0.51 mm (0.020 in) air gap on one side and 1.52
mm (0.060 in) on the other side.
The nominal forcer height out of the track is 2.5 mm (0.10 in). The flatness can deviate up an
additional 0.38 mm (0.015 in) for a total of 2.92 mm (0.115 in) from the track edge to the forcer coil.
The flatness can also deviate down 0.38 mm (0.015 in) for a total of 2.2 mm (0.085 in) from the track
edge to the forcer edge.
