Relay sockets are a type of electrical component that control power to a device or system when a signal is received. These relays work using two different applications and principles which are voltage feedback and magnetic field interaction. This article will look at these two applications and the working principle of the relays.

Voltage Feedback

Voltage feedback is one of the two most common applications for relay sockets. In this application, a signal voltage is used to control the relay. When the signal voltage is high, the relay is switched on, and when it is low, the relay is switched off. A signal voltage is usually generated by a sensor or controller, and can be either AC or DC depending on the application.

The relays themselves are usually comprised of an electromagnet and a spring return mechanism, the purpose of which is to move the electromagnet plunger when the signal voltage is present. The plunger, when activated by the signal voltage, engages the external contacts of the relay socket, which then control power to the device or system.

Magnetic Field Interaction

The second application of relay sockets is magnetic field interaction. In this application, when a magnetic field is present around the relay, the plunger is activated. The plunger, when activated, engages the external contacts of the relay socket, which then control power to the device or system.

Magnetic field interaction relays work by taking advantage of the inclination of a magnet to move in the presence of a magnetic field. This inclination is the basis of the operation of the relay, and it works by creating a magnetic field which, when generated, activates the plunger and engages the external contacts, thus controlling power to the device or system.

Working Principle

The working principle of relay sockets is relatively simple and can be summarized as follows: When a signal voltage or a magnetic field is present, the relay is activated, which then switches the external contacts of the relay socket, thus controlling the power to the device or system.

The mechanical plunger works by taking advantage of the induction effect of the signal voltage or magnetic field, and when activated, the plunger is drawn towards the external contacts of the relay socket. When the plunger is activated, it engages the external contacts, thus allowing current to flow through the device or system.

The main advantage of using relay sockets is the ability to control the power to a device or system using a signal voltage or magnetic field. Relay sockets can be used in a wide variety of applications, ranging from controlling the power to a light switch to controlling the speed of a motor. In addition, they are versatile enough to work with both AC and DC signals, making them a popular choice for many applications.

Relay sockets are a reliable and cost-effective way to control the power to a device or system when a signal voltage or magnetic field is present. Their simple working principle makes them easy to design and implement, and their versatility makes them suitable for a wide range of applications.
