In order to make things easier for you, it's included in the Cylinder, Threaded - M18 package. With an operating temperature of -20°C~60°C, proximity sensors can work efficiently. The rate should be 100Hz to ensure that switch of the proximity sensors performs its function. It's important that the reed switch's internal contacts pass 100mA for the proximity sensors to work. The proximity sensor can be used in the Bulk package.
