We have included it with the Cylinder, Threaded - M30 package in order to make it easier for you. At temperatures of -40°C~85°C, proximity sensors work well. Electronic components have 4 pins. To maximize efficiency, a proximity sensor should have its supply voltage set to 24V. Temperatures as low as [0] can be reached by proximity sensors. It is not possible for the proximity sensors to operate above 85°C. To ensure that the proximity sensors perform their duties, the rate should be 100Hz. It's important that the reed switch's internal contacts pass 200mA so the proximity sensors work.
