The Cylinder, Threaded - M12 package already includes it for your convenience. When the operating temperature is -40°C~70°C, proximity sensors will work well. If you want proximity sensors to perform at their best, you should set their supply voltage to 30V. To ensure that the proximity sensors are functioning properly, the rate should be set to 100Hz. To make proximity sensors work properly, the reed switch's internal contacts should be conducting 200mA current.
