We have included it as part of the Cylinder, Threaded - M18 package for your convenience. When the operating temperature is -25°C~70°C, proximity sensors are able to function properly. There are 4 pins on this electronic component. It is recommended that the supply voltage of proximity sensors be set to 30V to achieve maximum efficiency. The rate should be 500Hz to ensure that switch of the proximity sensors performs its function. It's important that the reed switch's internal contacts pass 200mA so the proximity sensors work. Set the current of this electronic part to 200mA if you want maximum efficiency. The proximity sensor should have a frequency of 500Hz.
