As an added convenience, the Module package includes it. Temperatures of -25°C~85°C are ideal for proximity sensors. Pins 4 are present on this electronic component. To maximize the efficiency of proximity sensors, it is recommended that the supply voltage be set to 30V. If the rate is 100Hz, then the proximity sensors will function. Reed switches work well with proximity sensors when their internal contacts pass 200mA current. DC circuits can be operated with a voltage of 30V without damaging the proximity sensors. In a DC circuit, proximity sensors should not be operating at a current below 10V, otherwise they will be dangerous.
