It is included with the package Cylinder, Threaded - M8 to simplify your life. The proximity sensors can work well with the operating temperature of -25°C~70°C. To maximize the efficiency of proximity sensors, it is recommended that the supply voltage be set to 24V. To ensure that proximity sensors work properly, the rate should be set to 5kHz. Reed switches are designed to use reed switches with internal contacts that pass 10mA current.
