It is included with the package Module to simplify your life. It is possible for proximity sensors to function well at -25°C~70°C. A 2 pin electronic component is used here. Proximity sensors should have their supply voltage set to 24V for maximum effectiveness. To ensure that proximity sensors work properly, the rate should be set to 500Hz. For DC circuits, proximity sensors can handle voltages as high as 30V without causing damage. There shouldn't be a current lower than 10V in the DC circuit of proximity sensors. Setting this electronic part's current to 100mA will maximize efficiency.
