The Cylinder, Threaded - M12 package already includes it for your convenience. Despite the operating temperature of -25°C~70°C, proximity sensors can function well. If you want proximity sensors to perform at their best, you should set their supply voltage to 300V. To ensure that proximity sensors work properly, the rate should be set to 30Hz. The current that the reed switch's internal contacts pass should be 200mA to make the proximity sensors work well.
