I've included it in the Cylinder, Threaded - M30 package for your convenience. When the operating temperature is -25°C~70°C, proximity sensors can function well. The pins on this electronic component are 4. A proximity sensor's supply voltage should be set to 30V for maximum efficiency. It is recommended that the rate be set to 250Hz in order to ensure that the proximity sensor switches operate properly. For the proximity sensors to work properly, the reed switch's internal contacts should pass 200mA current. This electronic part should be operated at 200mA current in order to maximize its efficiency. It is necessary to set the frequency of proximity sensor to 250Hz in order to make it work.
