As a convenience to you, it has been included in package Cylinder, Threaded - M12. When the operating temperature is -25°C~70°C, proximity sensors will work well. This electronic component has 4 pins. It is recommended that the supply voltage of proximity sensors be set to 24V for maximum efficiency. There is a minimum operating temperature for proximity sensors of -25°C. Temperatures above 70°C are not acceptable for proximity sensors. In order to ensure that the proximity sensors perform their function, the rate should be set to 1.3kHz. To make the proximity sensors work properly, the internal contacts of the reed switch must pass 500μA.
