The application field and working principle of ARK2121L1502E-T is wide-ranging. This product is mainly used as a reversing photoelectric switch, making it usable in a variety of applications such as safety devices, forward/reverse control, material handling, and mobility assistance. In certain areas, it can also be used for remote sensing, proximity sensing, and automation.

The ARK2121L1502E-T utilizes a photomagnetic switch technolo- gies to reversably detect and regulate the direction of the wire con- nected to its detection terminal. The product has a built-in luminosity detector, hall element, and current limiting. When the product is set up, an electrical current is sent through the luminescence detector, which targets the infrared light emiting from the LED. When the LED is turned on, the detector receives an electromagnetic signal that will be further pro- cessed in the following steps.

The hall element within the product receives the signal from the luminessence detector and transmits it to the bipolar switch. The switch then amplifies the signal which causes a current to flow in the electromagnet that is located at the top of the product. This current causes the magnet to attract the steel housing, thus forming a circuit. When the current stops flowing, the magnet releases the steel housing, which signifi- cantly weakens the magnetic field and causes the circuit to break.

To basically sum up, the ARK2121L1502E-T application field and working principle are based on a photomagnetic switch technolo- gies that allow it to reversably detect and regulate the direction of the wire connected to its detection terminal. The product’s internal components work in tandem in order to detect and server as an actuator for reversing purposes by forming and breaking circuits when the LED lights up and dims down.
