Passive Magnetic Speed Sensors

aitek instrument passive magnetic speed sensors

Control and protection circuits have relied on variable reluctance technology for years. With few components and no moving parts, the passive magnetic speed sensors can provide a signal from the inside of an aircraft engine at temperatures approaching 425°C or from the hub of an automobile wheel at high shock and vibration. The advantages of these sensors are:

  • High reliability
  • Simple installation
  • Long life due to no moving parts or contacts
  • Self powered operation
  • Wide variety of shapes and sizes
  • Easy alignment
  • Can be designed for almost any environment

Due to their flexibility, you will find Al-Tek variable reluctance sensors in everything from low-cost consumer products to highly-accurate automotive engine ignition systems to flight-worthy aircraft engine controls.
