TRACKER™ NSE-5310
Position Sensor and Evaluation Pack
1 General Description
2 Key Features
Smallest Size: Chip-scale packaging as small as 3.9 x 2.5 mm
The TRACKER™ NSE-5310 position sensor is a magnetic sensor
array with integrated on-chip digital encoding. With smallest size,
0.5µm resolution and low sensitivity to external magnetic fields, this
miniature position sensor is a robust and cost-effective solution for
precision positioning.
Accurate, Non-contact Sensing: 0.5µm resolution, < 2µm
repeatability
Complete System on a Chip: Sensing and encoding
integrated in one ingeniously small package
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 TRACKER NSE5310 position sensors for a single I²C bus.
Direct Digital Output (I²C): Eliminates need for external pulse
counters
Robust: Insensitive to light, shock, vibration and particulates;
less stringent mounting alignment
The highest-resolution magnetic encoder available, the TRACKER
NSE-5310 position sensor is insensitive to light, shock, vibration, and
high-particulate environments.
Absolute Performance: Zero reference, automatic gain &
offset correction
3 Applications
The TRACKER NSE-5310 position sensor is ideal for optical and
imaging applications, such as focus and optical image stabilization
as well as applications in consumer electronics, precision biomedical
devices, industrial instrumentation and defense/security. Its small
size makes it perfect for creating tiny, integrated closed-loop motion
systems using micro motors, such as New Scale’s SQUIGGLE®
motor.

5 System Overview
The TRACKER NSE-5310 magnetic encoder achieves its precision through a linear array of eight Hall-effect sensors on the chip that measure
the spatially varying magnetic field produced by moving a multi-pole magnetic strip above the sensor.
The TRK-1T02-E evaluation pack includes a TRACKER NSE-5310 mounted in a TSSOP 20 package with flex cable and a suitable linear
magnetic strip, a MC-31MB interface card and New Scale Pathway™ software to facilitate evaluation. The system can be connected to your
computer using a USB interface providing direct position information to your application.
TRACKER NSE-5310 in TSSOP or dice-on-foil packaging is available. Custom TRACKER NSE-5310 packaging such as wafer-level chip scale
packaging and chip-on-board packaging can also be provided for qualified OEMs. Minimum order quantities may apply.

6 Functional Description
Moving a multi-pole magnetic strip over the Hall array on the encoder chip generates internal sinusoidal (SIN) and phase-shifted sinusoidal
(COS) signals. These signals are filtered and transformed into angle (ANG) and magnitude (MAG), representing the absolute linear position of a
2mm long pole pair on the magnetic strip. Position information is read via I²C interface (SDA, SCL).
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. It also provides an absolute magnitude of the magnetic field intensity, which is used to detect the end of the magnetic
strip and thereby serves as a built-in zero reference.
The TRK-1T02-E Evaluation Pack is a full- featured development platform for the TRACKER NSE-5310 Position Sensor. The MC-31MB
interface card accepts the I²C input from one or two TRACKER NSE-5310 sensors, and connects via USB to your PC. Use the New Scale
Pathway™ Software to view and collect position information. This development kit provides for easy sensor evaluation and system development.
