We have included it as part of the Cylinder, Threaded - M12 package for your convenience. With an operating temperature of -25°C~70°C, proximity sensors can work efficiently. To maximize the efficiency of proximity sensors, it is recommended that the supply voltage be set to 24V. It is recommended that the rate be set to 1.3kHz in order to ensure that the proximity sensor switches operate properly. Reed switches' internal contacts should pass 500μA current to make proximity sensors work.
