You will find it included in the Cylinder, Threaded - M18 package to make it easier for you. A temperature of -25°C~70°C is a suitable operating temperature for proximity sensors. It is recommended that the supply voltage of proximity sensors be set to 24V to achieve maximum efficiency. In order for the proximity sensors to perform their function, the rate must be 2kHz. It's important that the reed switch's internal contacts pass 10mA so the proximity sensors work.
