It's included in Cylinder, Threaded - M8 so you can find it easily. It is possible to use the proximity sensors at -40°C~85°C. The pins on this electronic component are 4. It is important that the rate of the proximity sensor be set at 2kHz so that the proximity sensor switch can function properly. DC circuits can withstand the maximum voltage of 24V without damaging proximity sensors. If the proximity sensors are in a DC circuit, their current shouldn't be lower than 12V, otherwise, there can be a problem. To maximize efficiency, set this electronic part's current to 13mA. 200mA output range works well for electronic components.
