Inductive Position Sensors for High-Reliability and Safety-Critical Applications

Offering significant advantages over existing Hall effect and other magnetic sensors, our sensor interface ICs measure linear and angular/rotation movement found in a variety of automotive, industrial, aerospace and commercial applications. They are excellent solutions for high-reliability and safety-critical industrial and automotive position sensor applications, such as automobile throttle body, transmission gear sensing, electronic power steering and accelerator pedals. These unique magnetic field sensors give accurate position measurements, are immune to stray magnetic fields and don’t require an external magnetic device. AEC-Q100 Grade 1 (−45 to +125 °C) and Grade 0 (−45 to +150 °C) certified and ISO 26262 compliant solutions are available.

Inductive Position Sensor Design Services

We are dedicated to simplifying your sensor design. We offer three different levels of sensor design support based on your requirements.

1. Free Service

This free tier has everything you need to develop your sensors. We offer you a custom sensor layout that fits your requirements and simulated results over air gap that can include a 3D system mechanical structure. 

2. Premium Project Service

This yearly subscription service includes expedited and expanded design simulations to help improve your time to market. The simulations speed up design by looking at more mechanical tolerance parameters before building a prototype, which facilitates quicker design iterations.

3. World Service

This yearly subscription service provides multi-project premium support, live debug support, Electromagnetic Interference (EMI)/Electromagnetic Compatibility (EMC) simulations, EMI/EMC lab support and onsite sensor design training to improve your time to market. In addition to quicker sensor design, the additional EMI/EMC simulations and lab support speed up sensor qualifications. The sensor design training helps your team learn to design their own sensors.
