It's included in Cylinder, Threaded - M18 so you can find it easily. Despite the operating temperature of -25°C~70°C, proximity sensors can function well. There are 5 pins on this electronic component. The maximum voltage of 30V can be applied to the proximity sensors without damage in DC circuit. A DC circuit with proximity sensors should not produce a current below 10V, otherwise, the circuit will present a safety hazard.
