It is included with the package Cylinder, Threaded - M8 to simplify your life. In terms of operating temperature, proximity sensors are capable of operating at -25°C~70°C. The pins on this electronic component are 3. A proximity sensor's supply voltage should be set to 30V for maximum efficiency. In order to ensure that the proximity sensors perform their function, the rate should be set to 1kHz. For the proximity sensors to work properly, the reed switch's internal contacts should pass 200mA current. A DC circuit can withstand a voltage of 30V without damaging the proximity sensors. The current drawn by the proximity sensors in the DC circuit should not be less than 10V, otherwise it will be dangerous. To maximize efficiency, set this electronic part's current to 200mA. A proximity sensor should have a frequency of 1kHz in order to function properly.
