Passive Speed Sensors
Also refer to the 70085 Series
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. The advantage of these sensors are:
High reliabilitySimple installationLong life due to no moving parts or contactsSelf powered operationWide variety of shapes and sizesEasy alignmentCan 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.
