Module includes it for your convenience. A temperature of -25°C~70°C is suitable for the operation of proximity sensors. It has a pin count of 3. Proximity sensors should have their supply voltage set to 24V for maximum effectiveness. It is important that the rate of the proximity sensor be set at 300Hz so that the proximity sensor switch can function properly. Reed switches are designed to use reed switches with internal contacts that pass 100mA current. The best way to increase the efficiency of this electronic part is to set the current to 15mA.
