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IPN。 Note 2 :ppm data refer to IPN corresponding to the subside output signal full degree. | ||||||
