Product Data Sheet

Variable Reluctance Digital Output Speed Sensor (VD)
Due to the active solid state signal conditioning integral with this variable reluctance speed sensor, it converts a sine wave signal output to produce a digital square wave signal with constant amplitude regardless of variations in speed.
