ALZ52B09T

The ALZ52B09T is a power relay with over 2 amps in current capacity. It is a normally closed contact type relay, which means that the contact remains closed until it is energized and is then open. This datasheet from Xiamen Elecsound Electronics Co., Ltd. describes its main application fields as well as its working principle.

Application Fields

The ALZ52B09T is suitable for applications such as motor control, lighting control, and other circuits with frequent energizing and de-energizing operations. It can be used in household appliances such as electric fans, electric heaters, washing machines, dishwashers, and so on. It is also suitable for industrial control circuits, office automation equipment, medical equipment, and automatic control systems..

Working Principle

The ALZ52B09T can be energized by an AC or DC voltage source. When the voltage is applied, the relay’s coil produces a magnetic field that closes the contact inside the relay. This closed contact then keeps the circuit energized allowing current to flow. When the voltage is removed, the current stops flowing and the contact opens, de-energizing the circuit.

The ALZ52B09T is designed with a high population of contact elements for increased reliability. Its contacts are rated for up to 2 amps of current that can withstand temperatures up to 125 degrees Celsius. The relay is also designed to minimize electrical noise, and it is protected against transient voltages.
