It is included with the package Cylinder, Threaded - M18 to simplify your life. It is possible for proximity sensors to function well at -40°C~85°C. A 3 pin electronic component is used here. A proximity sensor's lowest operating temperature is -40°C. Temperatures above 85°C are not allowed for proximity sensors. To ensure that proximity sensors work properly, the rate should be set to 600Hz. 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 55V 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 13mA will maximize efficiency.
