Coilcraft Transformers for Ultrasonic Sensing

Coilcraft's high-quality ultrasonic transformers are key components that help achieve wide-ranging, accurate ultrasonic distance sensing. They offer fixed inductance values that are stable up to 125°C ambient (AEC-Q200 Grade 1), which is critical for accurate and reliable system performance, especially in automotive and industrial environments.

Coilcraft’s WA8351-AL ultrasonic transformer has a fixed inductance value,
is stable up to 125°C ambient and is ideal for automotive use.

Automotive Applications
  • Automated parking assist
  • Blind-spot warning
  • Presence and proximity detection
  • Automotive kick-to-open lift gates
    (smart trunk opener)
Industrial Applications
  • Liquid level sensing and inventory management
  • Robotics landing assist and obstacle detection
  • Anti-collision on aerial work platforms
  • Forklift monitoring and control
  • Industrial door-opening sensing
