Datasheet - Detailed Description
7 Detailed Description
The TRACKER measures the spatially varying magnetic field produced by moving a multi-pole magnetic strip over a Hall sensor array on the
NSE-5310 chip
(see Figure 3)
. The internal sinusoidal (SIN) and phase-shifted sinusoidal (COS) signals are filtered and transformed into angle
(ANG) and magnitude (MAG), representing the absolute linear position within a 2 mm pole pair on the magnet. Interpolation with 12 bit (4096)
resolution yields 0.5 μm position resolution. Automatic gain control (AGC) adjusts for DC bias in the magnetic field and provides a large
magnetic field dynamic range for high immunity to external magnetic fields. The absolute magnitude of the magnetic field intensity is used to
detect the end of the magnetic strip and serves as a built-in zero reference. The length of the magnetic strip determines the maximum measured
stroke.
Note:
Hall sensor array and on-chip digital encoder yield absolute position within a pole pair. Use a system processor to count pole pair
crossings for long-range absolute position.

The over travel pole crossing provides a precision home position and eliminates the need for a secondary zero reference sensor.
