I've included it in the Cylinder, Threaded - M18 package for your convenience. With an operating temperature of -25°C~70°C, proximity sensors can work efficiently. If you want to get the most out of proximity sensors, you should set the supply voltage to 24V. For the proximity sensors to work properly, the rate needs to be 1kHz. It's important that the reed switch's internal contacts pass 10mA for the proximity sensors to work. In DC circuits, proximity sensors can withstand a maximum voltage of 24V. There must be at least 12V current flowing through the proximity sensors in the DC circuit to prevent an electric shock.
