High Frequency (RF) Relays are electric relays that have been designed to transfer high frequency signals over short to medium ranges. The ARS11A4H is a high frequency (RF) relay designed to provide superior operation and performance when transferring signals at or greater than 10MHz. This relay possesses a wide range of application fields and a unique working principle that makes it suitable for a variety of applications.

Applications

The ARS11A4H is suitable for applications such as wireless communication, datacomm, and military/defense. These areas will benefit from the high frequency capability of this relay as they need to transfer data, signals, and power various distances. It is also beneficial for testing and measurement. This relay can be used as an interconnection device for signal transfer between multiple locations.

The ARS11A4H is also useful for automotive applications, such as in safety systems. This relay is a reliable component for transferring signals on and off vehicle harnesses and systems, as it is designed to work in a variety of environmental conditions. Its higher frequency capability makes it suitable for transmission of data between computer and electronic parts for adding features and adjustability in the car.

Working Principle

The ARS11A4H is an SPST-NO RF relay featuring a Form A nominal contact rating of 100mA. It works by completing or breaking a circuit when activated. This relay operates by using electromagnetic force which enables the contacts to move freely while providing high speed actuation (switching) and low power consumption. This electromagnetic force is created by the applied coil, which is placed in a closed magnetic circuit. When a direct current is applied to the coil, a magnetic field is created and the armature is attracted and closes the contacts of the relay. When the current is removed from the coil, the armature is dropped and the contacts open.

The ARS11A4H is designed for frequencies of up to 1MHz and is capable of operating in temperatures ranging from -55°C to +125°C. This relay is designed to provide maximum performance when switching RF signals. It features two contacts, which can be used as a normally open (NO), normally closed (NC), or a changeover switch (Form B). This makes it suitable for a variety of applications.

Conclusion

The ARS11A4H is a high frequency (RF) relay that is capable of transferring signals at or greater than 10MHz. It has a wide range of applications such as wireless communication, datacomm, and automotive systems. This relay works by using electromagnetic force which allows for high speed actuation and low power consumption. Its small size and high frequency capability makes it an ideal choice for a variety of applications.
