We have included it with the Cylinder, Threaded - M30 package in order to make your life easier. A temperature of -25°C~70°C is a suitable operating temperature for proximity sensors. The maximum efficiency of proximity sensors can be achieved by setting their supply voltage to 24V. To ensure that proximity sensors work properly, the rate should be set to 1kHz. If the proximity sensors are to function properly, the current passing through the reed switch's internal contacts should be 10mA.
