Variable Reluctance Speed Sensor (VR)

Product Data Sheet

Variable Reluctance Speed Sensor (VR)
The collapse of magnetic field due to the interruption by a ferrous gear tooth provides an analog signal output (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.
