YD69 CW/CCW Dual-channel Sensor
Hall Dual-channel speed sensor has good low and high frequency characteristics. The low frequency is as low as 0Hz, can be used for zero-speed measurement of rotating machinery, because the sensor can provide a certain phase of two speed signals, so you can judge for CW or CCW; high frequency is as high as 20KHz, can meet the high-speed measurement requirements of vast majority of industrial field.
A. Hall Dual-Channel Sensor Overview
Hall Dual-Channel Sensor is installed on the shell of the measured machine, inducting the raised part or concave slots of the magnetizer, it shows the corresponding level, it is used to detect axis of rotation speed, linear velocity. The method to get the acceleration of the measured machine is by calculation processing. The sensor has good low and high frequency characteristics. The low frequency is as low as 0Hz, can be used for zero-speed measurement of rotating machinery, because the sensor can provide a certain phase of two speed signals, so you can judge for CW or CCW; high frequency is as high as 20KHz, can meet the high-speed measurement requirements of vast majority of industrial field. It is contactless measurement between the sensor and the measured gear, no wearing and easy installation. The output waveform is square wave that duty cycle for about 50%.
Hall Dual-Channel Sensor has the features of great adaptability, wide speed range, wide temperature range and strong vibration resistance.
B. Hall Dual-Channel Sensor Technical Parameters
(The parameters of phase difference is the data when the speed gear modulus is 2, in line with DIN867 standard.)
