IDT's contactless position sensor solutions are magnet-free, significantly reducing materials costs while providing immunity to magnetic stray fields – a mandatory requirement for many applications, particularly in automotive. Instead of magnets, the inductive position sensors interface with low-cost PCB-based coils and simple metallic targets, providing single-chip design flexibility for rotary end-of shaft (on-axis) sensors, rotary side shaft (off-axis) sensors, linear motion sensors, and arc motion sensors; from small angles up to full 360° absolute angle sensing. The devices are automotive-qualified and ISO 11452-8 compliant, making them suitable for use in a wide range of automotive, industrial and consumer applications.

About Contactless (Non-contact) Inductive Position Sensor ICs
At their most basic function, a position sensor is any device that provides measurement data based on position of a moving object. Traditional magnet-based solutions measure angular position using variations of magnetic field amplitude induced by the displacement or rotation of a moving magnet. However, these solutions are expensive and have operating temperature limitations. IDT's no-contact, magnet-free inductive position sensor ICs interface with thin PCB-based coils and a metallic target to determine position and provide accurate position data back to the system. These inductive, contactless solutions offer significant advantages in cost, temperature range, reliability, design flexibility, and immunity to magnetic stray fields.
