The Cylinder, Threaded - M18 package already includes it for your convenience. When the operating temperature is -25°C~70°C, proximity sensors will work well. If you want proximity sensors to perform at their best, you should set their supply voltage to 60V. To ensure that the proximity sensors are functioning properly, the rate should be set to 500Hz. To make proximity sensors work properly, the reed switch's internal contacts should be conducting 100mA current. In DC circuits, proximity sensors can receive a voltage up to 60V without being damaged. DC proximity sensors should not have currents lower than 6V, or they could damage the circuit.
