Reluctance (VR) Speed Sensors with Complementary Outputs Diagram

Non-contact magnetic sensors that measure the collapse of magnetic field due to the interruption by a ferrous gear tooth. These sensors provide two analog signal outputs (sine wave) that does not require an outside power source.  This sensor is suitable for speed sensing with a range from 30 to 1000 inches per second with a target gear from one tooth per revolution to 32 pitch gear.
