Power Relays Over 2 Amps

ALF1T18 Application Field and Working Principle

ALF1T18 relay is a type of latching relay, suitable for use in applications that require long-term circuit reliability. This type of relay is designed to be specifically used in low-voltage DC power circuits, such as 12V DC and 24V DC. It features a high rated current of 2A, and can switch from low- to high-voltage. It is also designed to be used in a wide variety of industrial applications.

In terms of application fields, the ALF1T18 relay can be used for switching circuits such as DC motors, lamps, and small household appliances, and is suitable for use in home automation systems, industrial control systems, and medical technology applications. As a latching relay, the ALF1T18 relay offers dependable switching performance over long periods of time, and permits reliable switching even in the presence of interference.

How the ALF1T18 Works

The ALF1T18 relay is based on a single-pole single-throw latching contact assembly. It features two sets of contacts – the main contacts and the latch contacts. The main contacts are connected in series to form a single-pole single-throw circuit. The latch contacts are connected in parallel to the main contacts, and they are used to set the switching state of the relay. The relay’s coil is energized either through a permanent magnet or an alternating current. When the coil is energized, the latch contacts move from their open (or off) state to their closed (or on) state. The open-before-closed contact arrangement ensures that the device is not energized until the latch contacts have closed.

The ALF1T18 relay has a unique latching mechanism, which makes it ideal for applications where reliability is of the utmost importance. This latching mechanism ensures that the relay is not energized until the latch contacts have been opened, and it ensures that the contacts remain in the same state until they are manually reset. The latching mechanism also ensures that there is no arcing or sparking when the contacts open or close.

Advantages of the ALF1T18 Relay

The ALF1T18 relay has several advantages over other types of relays. It has a high rated current of 2A, which ensures that it can handle heavy loads. It also has a wide operating temperature range of -40°C to +110°C, which makes it suitable for use in a wide variety of environments. The latching mechanism also ensures that the relay is reliable and dependable over long periods of time. The open-before-closed contact arrangement also ensures that no arcing or sparking is generated when the contacts open or close.

In addition, the ALF1T18 relay has a uniquely low power consumption of just 0.2W, which means that it is suitable for use in low-power applications. It also has a high mechanical life of up to 10,000,000 operations, which makes it ideal for applications where reliability and durability are essential. Finally, the ALF1T18 relay is extremely compact, making it ideal for applications where space is at a premium.
