This is included with the Cylinder, Threaded - M18 package for your convenience. A temperature of -25°C~70°C is suitable for the operation of proximity sensors. There are 3 pins on this electronic component. It is recommended that the supply voltage of proximity sensors be set to 24V for maximum efficiency. The rate should be 100Hz to ensure that switch of the proximity sensors performs its function. In order for proximity sensors to work properly, the reed switch's internal contacts should pass 200mA current. As long as the proximity sensors are not damaged, the maximum voltage of 30V can be applied to them. There should be no current flowing through the proximity sensors in the DC circuit below 10V, otherwise it could prove hazardous.
