Building With Inductive Position Sensors: Tips and Tools

Whether you are ready to lay out your own PCB-based inductive position sensor or want to purchase a pre-built evaluation sensor for rapid system prototyping, we can assist you with your project. Our Position Sensor Library is an excellent starting point. We also offer linear and rotary evaluation board (EVB) kits to quickly prototype your system application, an Integrated Programming and Calibration Environment (IPCE), programmers and software that simplify inductive position sensor evaluation, testing and programing. If you don’t see what you need here, contact our technical support team for advanced sensor information and other assistance with your project.

Three Simple Steps for Building Your Own PCB

Step 1

Choose and download a sensor layout from the position sensors library.

Go to Position Sensors Library

Step 2

Order the matching LX3302AQPW-EASY sensor IC.

Go to Sensor ICs

Step 3

Build and run your system. Connect with our technical support team if you need any assistance.

Pro Sensor Kits

These kits come with your choice of an EVB, an IPCE programmer for accurate sensor measurement and programming and all the cables needed to interface the sensors and programmer to a computer. These programmers simplify designing, building and evaluating your own sensor applications.

Nano Sensor Kits

These kits speed up your time to market by combining a linear or rotary sensor with a programmable PIC18F microcontroller (MCU). Offering many of the same capabilities of the Pro kits, these are smaller reference designs that can be used in your end application.

IPCE Setting Window

This window, which is the most powerful and yet simple-to-use feature of the software, provides an easy way to change the IC’s operation to meet your system requirements. You can adjust all EEPROM parameters, including I/O interface options, sampling rate and analog front end, or make small adjustments to the calibration points.

IPCE Measurement Window

Instantly capture data by clicking on the "capture data" button or do it automatically through the TCP/IP protocol. Then use the “Save Datalog” button to easily save the captured data in an Excel file. A unique sensor debug feature also allows you to capture the raw PCB sensor output, which is perfect when you want to understand how your unique mounting may be impacting the design. This mode gives you access to the internal Analog-to-Digital Converter (ADC) values, including fault diagnosis information to help you rapidly bring your sensor to production.

IPCE Analysis and Autocalibration Window

After measuring the sensor, use the analysis window to easily implement sensor linearization with the auto-calibration function. The software provides the optimal accuracy that can be achieved using the IC’s built-in calibration memory, or you can use an external Microchip MCU to achieve even better accuracy.

Position Sensor User Library for Creating Your Own Designs

Our Inductive Position Sensor User Library eliminates the need for you to do any equations, calculations or IC programming. Just add these PCB sensor layouts to your own board and order the right sensor IC to build your own application. Then connect to either the PWM, analog or SENT interface to the system controller and start reading position data. The sensor library offers linear and rotational sensor examples. You can use them as is or follow one of the instructions guides for modifying the examples to meet your specific requirements.
