We have included it with the Cylinder, Threaded - M18 package in order to make it easier for you. The proximity sensors can operate at a temperature of -25°C~70°C without any problems. The supply voltage of proximity sensors should be set to 30V for maximum efficiency. If the rate is 400Hz, then the proximity sensors will function. Reed switches should pass 200mA current through their internal contacts to work with proximity sensors. This electronic part should be operated at 200mA current in order to maximize its efficiency. In order for proximity sensor to function, the frequency should be set to 400Hz.
