To make it easier for you, this Sensor is included with the Cylinder, Threaded - M18 package. The proximity sensors can work well with the operating temperature of -25°C~70°C. It is recommended that the supply voltage of proximity sensors be set to 24V for maximum efficiency. The rate should be 1.2kHz to ensure that switch of the proximity sensors performs its function. The current that the reed switch's internal contacts pass should be 500μA to make the proximity sensors work well.
