This is included in the Cylinder, Threaded - M30 package to make it easier for you to use. In terms of operating temperature, proximity sensors are capable of operating at -25°C~70°C. It's got 4 pins. It is recommended that the supply voltage of proximity sensors be set to 30V to achieve maximum efficiency. In order to ensure that the proximity sensors perform their function, the rate should be set to 250Hz. You need the reed switch's internal contacts to pass 200mA to work. You should set the current of this electronic part to 200mA if you want to maximize its efficiency. Ideally, the frequency of proximity sensor should be 250Hz.
