Proximity sensors have their own voltage ratings, which are used to ensure that their work in peacetime will not be caused by unstable voltages and instability. The voltage drop of the proximity sensor is the voltage of the sensor when the sensor is measured when the sensor is turned on. The ripple voltage is the alternating voltage, which is superimposed on the operating voltage, which is usually expressed as the arithmetic mean of the average.
The switching frequency is a suitable large number from one attenuation state to one without attenuation. Proximity to the interference voltage of the sensor can refer to a short supply voltage spike, which may damage the unprotected sensor. The delay of this switch is the time required for the power supply voltage proximity switch to work.
When the operating voltage increases, the pulse is not increased, and the error of the output signal can be suppressed during the TV time. If the limit current is exceeded, the output will be shut down and periodically released until the short circuit is released. This limit protects the DC sensor with a protection function to prevent the input supply voltage polarity.
