注①:测试信号为单脉冲,过冲后传感器会进入自恢复状态,状态指示灯灭,需要约50ms恢复到正常工作状态. Note 1: The test signal is a single pulse. After overshooting, the sensor will enter the self-recovery state, and the status indicator will be off. It takes about 50ms to restore to the normal working state.
注②:ppm数据均参考副边输出信号满度对应的I_PN. Note 2 :ppm data refer to IPN corresponding to the subside output signal full degree. 传感器机械尺寸图 Mechanical dimensions of the sensor 单位：mm Unit：mm
