Position Sensor Family


  • Inductive based with no magnet required
  • Immune to magnetic stray fields
  • Flexible; same IC for many applications
  • Fully automotive qualified

IDT's contactless position sensors are magnet-free, significantly reducing materials costs while providing immunity to magnetic stray fields, a requirement for many applications, particularly in automotive. Instead of magnets, the 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.
