Push-in terminals utilize the same internal mechanics of the spring clamp. The main difference between the two is that push-in terminals allow for automated robotic wiring of the power supply and cabinet devices. The wiring robots detect the side-by-side openings of the wiring entry, visually inspect them, insert the wires into the power supply and connect them to the other components in the control cabinet. This means that the CP power supplies with push-in terminals can help support automated assembly systems where machines insert wires and components in a quick, accurate and repetitive means.
