Hi G relays are electronic switches that allow low-power signals to control high-power circuits. They are widely used in various applications, including military, aerospace, computers, and industrial equipment. Relays are a type of hermetically sealed relay that meets the strict specifications and requirements of the military and aerospace industries.
Today, we will discuss the basics of relays, how they work, their features and functions, and their common applications.
The Basics of Hi G Relays
Hi G relays are specialized and operate in high shock and vibration environments. Hi G stands for high G-force, which indicates that these relays can withstand high levels of acceleration and deceleration. This fantastic component can also operate in extreme temperatures, from -55°C to +125°C. Relays are hermetically sealed, which means they are completely sealed and protected from the environment, including dust, moisture, and other contaminants.
How Do Relays Work?
Relays work by using an electromagnetic field to open or close a switch. When a low-power signal is applied to the relay, it creates an electromagnetic field that pulls a metal armature toward a stationary contact. This action closes the switch and allows current to flow through the circuit. When the signal is removed, the electromagnetic field disappears, and the metal armature returns to its original position, opening the switch and breaking the circuit.
Features and Functions of Hi G Relays
Hi G relays have several features that make them ideal for harsh environments. They are designed to withstand high levels of shock and vibration, making them ideal for use in aerospace applications. They are also hermetically sealed, which means they are completely sealed to prevent any external factors from affecting their performance.
One of the key features of relays is their ability to switch high voltages and currents. This makes them ideal for power distribution and motor control systems. Another important feature of relays is their ability to switch high-frequency signals. This makes them ideal for use in communication systems, radar systems, and other high-frequency applications.
Common Applications of Hi G Relays
Now that you know the basics of relays, let us proceed to their common applications. As you might not know, Hi G relays are used in various applications in different industries. Here are some of the most common applications of relays today:
Civil Aviation
Relays are also used in civil aviation, including flight control, landing gear, and engine control. They are designed to operate in bad environments and can resist high levels of electromagnetic interference. These relays are also highly reliable, ensuring the safety of passengers and crew.
Satellites
Earth observation, navigation, and communication satellite systems all use relays. They are capable of functioning in space vacuum and are made to withstand radiation. Not only are these relays small and light, but they are also perfect for space applications.
Computer Equipment
Computer equipment like data storage devices, printers, and power supplies also uses relays. These systems require high-speed switching and low power consumption, and relays are ideal for these applications because they provide reliable performance and low power consumption.
Business and Office Machines
Relays are used in copiers, printers, and other office machines. They switch high currents and voltages and can handle high-frequency signals. These relays are also highly efficient, ensuring the smooth operation of office equipment.
Industrial Applications
Relays are often used in motor control systems, power distribution systems, and process control systems. These systems require high-speed switching and high reliability, and relays are ideal for these applications because they provide reliable performance and high switching speed.
Hi G relays are versatile components that can be used in various applications in different industries. Their hermetically sealed design, great shock and vibration resistance, and high-temperature range make them ideal for use in harsh and multiple environments. Relays are also made for higher reliability and long life, making them ideal for critical applications.
