VB-D94 Series positive and negative dual channel speed sensor

Brief introduction

VB-D94 series of positive and negative double-channel speed sensor is installed on the speed measuring end cover, induction of the magnet on the convex teeth or concave groove, the corresponding upper and lower level, used to detect the speed of the axle, linear speed. The sensor has good low frequency and high frequency characteristics, low frequency up to 0Hz, can be used for zero speed measurement of rotating machinery, because the sensor can give two speed signals with a certain phase difference, so can progress positive and negative discrimination; The high frequency can be as high as 20KHz, which can meet the requirements of high speed measurement in most industrial fields. The sensor has no contact with the measured gear, no wear, easy installation, and the output waveform is a square wave with duty cycle of about 50%.
