It is included with the package Module to simplify your life. It is possible for proximity sensors to function well at -25°C~100°C. For DC circuits, proximity sensors can handle voltages as high as 25V without causing damage. There shouldn't be a current lower than 5V in the DC circuit of proximity sensors.
