I've included it in the Cylinder, Threaded - M30 package for your convenience. It is possible for proximity sensors to operate effectively at temperatures below -40°C~70°C. A component with 4 pins is included in this electronic component. It is recommended that the supply voltage of proximity sensors be set to 30V for maximum efficiency. In order to ensure that the proximity sensors perform their function, the rate should be set to 200Hz. Reed switches should pass 200mA current through their internal contacts to work with proximity sensors.
