Proximity sensors can be found in many different applications, from industrial machinery to locomotives. They are often used to switch devices on and off, detect objects in the environment, and provide feedback on the operating parameters of the application. One of the most common proximity sensors used in industrial applications is the DU5.

The DU5 is a two-wire AC-operated proximity sensor. It operates at a frequency of 100–400kHz, and uses an internal voltage transformer to detect objects within a range of 20–240V AC. It can be configured to switch a device on or off as a result of its detection. The device contains two coils of wire, one for sensing and the other for receiving. When an object is detected, the current supplied by the sensing coil is disrupted, triggering the metal oxide semiconductor (MOS) transistor to switch off. This signals the DU5 to send an output voltage, which in turn switches the receiving coil on.

The DU5 has several advantages over other proximity sensors. Its small size makes it suitable for use in applications where space is limited. Additionally, it uses a low-cost voltage transformer, which helps reduce its cost. The DU5 is also an extremely reliable device and is capable of sensing objects with different shapes and sizes. Furthermore, the sensing range of the DU5 can be extended to cover a longer distance if necessary.

The DU5 has a wide range of applications. It is often used in industrial machinery, such as conveyor belts and automated production lines, to switch the machine on and off. It can also be used to detect and control the operation of locomotives, such as when the train\'s emergency brakes need to be applied. Additionally, it can be used to detect objects in the environment, such as when a person is too close to a hazardous area. The DU5 can also be used to provide feedback on the operating parameters of the application, such as the speed or acceleration of an engine.

The DU5 is a versatile and reliable device that is suitable for a wide range of applications. Its two-wire AC operation makes it easy to install and maintain, while its low cost makes it an attractive option. By using an internal voltage transformer, the DU5 is able to detect objects within a range of 20–240V AC, which makes it suitable for use in a variety of environments. Furthermore, the DU5\'s sensing range can be extended if necessary, making it suitable for longer distance sensing needs. Overall, the DU5 is an ideal choice for those looking for an effective and affordable proximity sensor.
