Power Relays, Over 2 Amps

G7Z-2A2B-20Z DC12 is commonly used in power relays, especially when the current to be controlled is over 2 amps. This type of relay switch is a latching type, which means that it can automatically keep the controlled load on or off after actuation. This makes it ideal for applications that require a continuous control with minimal manual interventions.

Working Principle

The working principle behind the G7Z-2A2B-20Z DC12 is quite simple; when a set amount of electricity is passed through the electromagnet, a magnetic field develops, which then causes a pair of contact points of the relay to close or open, or both simultaneously. The contacts are typically made of silver alloy in order to allow for a stable and reliable operation.

The set amount of electricity needed to actuate the relay is typically between 5 and 20mA, depending on the model. The current has to be passed through the coil to generate the magnetic field, which then allows the contact points to open or close in order to control the load.

Application Fields

G7Z-2A2B-20Z DC12 relays are used in a variety of applications but are particularly useful for power distribution systems. Two of the most common applications are motor control and lighting control. Motor control is particularly important as it helps to ensure that the motor is working efficiently and will not overload. Similarly, lighting control systems are also highly important and are used to automate the switching of lights off and on, as well as to adjust the level of brightness in a particular area.

Other applications where G7z-2A2B-20Z DC12 is used include motor starters, safety shut off systems, and even automatic gate openers. Due to the latching action of this type of relay, it is particularly well-suited for these applications where a permanent control is needed.

Conclusion

In conclusion, G7z-2A2B-20Z DC12 is a versatile latching type relay switch, which can be used for a variety of power control applications including motor and lighting control, motor starters, safety shut-off systems, and automated gate openers.
