With the Cylinder, Threaded - M30 package, it is included for your convenience. It is possible for proximity sensors to operate effectively at temperatures below -25°C~70°C. Pins 5 on this electronic component. If the rate is 380kHz, then the proximity sensors will function. In order for proximity sensors to work properly, the reed switch's internal contacts should pass 20mA current. DC circuits can withstand the maximum voltage of 30V without damaging proximity sensors. In a DC circuit, the proximity sensors must have a current higher than 10V.
