We have included it with the package Cylinder, Threaded - M8 to make it easier for you. A temperature of -25°C~70°C is suitable for the operation of the proximity sensors. A 4 pin electronic component is used in this application. -25°C is the lowest operating temperature that can be reached by proximity sensors. Sensors cannot operate above 70°C. To ensure that the proximity sensors perform their function, the rate should be set to 25Hz. At a nominal supply current of 13mA, proximity sensors will operate normally.
