Sensors, as key devices that convert sensing signals into standard signal outputs, have three internal wires that each carry important functions

Firstly, the power cord, usually marked in red, is the energy supply line for the normal operation of the sensor, ensuring its continuous and stable operation.

Secondly, the signal line, commonly represented in green, serves as an information transmission bridge between the sensor and the control circuit, responsible for accurately and timely transmitting the sensed signals to the control circuit.

Finally, the grounding wire, marked in black, is an important circuit connecting the sensor to the ground. It forms a loop in the circuit, ensuring the normal flow of current and ensuring the safety and stability of the circuit.

In the field of automation, sensors are widely used in various applications such as access control, automatic restrooms, and lighting control due to their convenient and efficient automatic control functions. Therefore, when using the sensor, it is necessary to correctly connect these three wires to ensure that the sensor can work properly and achieve the goal of automation control.
