8.7 Magnetic Strip Requirements
The NSE-5310 requires a magnetic strip with alternate poles (North-South) of pole length of 1 mm and pole pair length of 2 mm. A half pole is
required at each end of the strip. The length of the strip determines the maximum measured stroke; it must be 3 mm greater than the stroke in 1
mm increments (1.5 mm on each end).
A circular magnet may be used to achieve off-axis rotary encoding.

8.7.1 Mounting the Magnet
Vertical Distance:
length of the magnets. However, the gap also depends on the strength of the magnet. The NSE-5310 automatically adjusts for fluctuating
magnet strength by using an automatic gain control (AGC). The vertical distance should be set such that the NSE-5310 is in the “green” range.
See Z-axis Range Indication (“Red/Yellow/Green” Indicator) on page 14
Alignment of Multi-pole Magnet and IC:
be placed exactly over the Hall array. A lateral displacement in Y-direction (across the width of the magnet) is acceptable as long as it is within
the active area of the magnet. The active area in width is the area in which the magnetic field strength across the width of the magnet is constant
with reference to the centerline of the magnet.
