It is included with the package Cylinder, Threaded - M8 to simplify your life. It is possible for proximity sensors to function well at -25°C~70°C. A 3 pin electronic component is used here. Proximity sensors should have their supply voltage set to 30V for maximum effectiveness. To ensure that proximity sensors work properly, the rate should be set to 1.5kHz. To make the proximity sensors work properly, the internal contacts of the reed switch must pass 200mA. 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 200mA will maximize efficiency. In order for the proximity sensor to work, its frequency should be 1.5kHz.
