NSE-5310 miniature position sensor technology
With integrated on-chip encoder for smallest size and highest
resolution
New Scale's M3
micro mechatronics module platform incorporates the TRACKER™ NSE-5310 position sensor,
developed in partnership with austriamicrosystems. Its small size
makes it perfect partner for the SQUIGGLE micro motor in creating
tiny, integrated closed-loop motion systems.
The NSE-5310 is a magnetic sensor array with
integrated on-chip digital encoder, which transforms a magnetic sine
wave into a direct digital position output. With 0.5 micron resolution and
size as small as 3.9 x 2.5 mm, it is a robust, cost-effective
alternative to miniature optical encoders for non-contact position
sensing.
On-chip encoding provides direct digital output using standard I2C
protocol, eliminating the need for external pulse counters.
Efficient control system communications allows up to two position sensors on a single I2C bus.
The highest-resolution magnetic encoder available, the NSE-5310 position sensor is insensitive to light, shock, vibration, and
high-particulate environments. It features low sensitivity to
external magnetic fields and can be used as a linear encoder or
off-axis rotary encoder.

Sensor operation
The NSE-5310 position sensor integrates a sensor array and encoder
on an SOIC. A linear array of eight Hall
effect sensors on the chip measures the spatially varying magnetic
field produced by moving a multi-pole magnetic strip above the
sensor.
The magnetic field generates internal sinusoidal and
phase-shifted sinusoidal signals. These signals are filtered and
transformed into angular and magnitude values, representing the
absolute linear position of a 2 mm long magnetic encoder strip pole
pair. The position information is read via an I2C interface.
Automatic gain control (AGC) adjusts for DC bias in the magnetic
field and provides a large dynamic input range of the magnetic field
for higher immunity to external magnetic fields. It also provides an
absolute magnitude of the magnetic field intensity, which can be
used to detect the end of the magnetic strip and thereby serve as a
built-in zero reference.
