As an added convenience, the Cylinder, Threaded - M30 package includes it. Temperatures of -25°C~70°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 250Hz, then the proximity sensors will function. Reed switches work well with proximity sensors when their internal contacts pass 200mA current. Setting the current of this electronic part to 200mA will maximize its efficiency. To make the proximity sensor work, the frequency should be set to 250Hz.
