70085 Series Passive 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 degrees C or from the hub of an automobile wheel at high shock and vibration. These sensors have high reliability, are easy to install due to easy alignment and can be designed for almost any environment. Due to their flexibility, you will find Ai-Tek variable reluctance sensors in everything from low-cost consumer products to highly-accurate automotive engine ignition systems to flight-worthy aircraft engine controls.
