Reed relays are high-performance, high-reliability, liquid-free switches that have been used in a variety of applications for decades. The HE721A2400 reed relay, produced by Stackpole Corporation, is designed to be a reliable choice for telecom and industrial applications. In this article, we will explore the application field and working principles of the HE721A2400.

The HE721A2400 reed relay is most commonly used in telecommunications applications due to its low current requirements. It can be used to switch between different telephony lines, or to switch between different internet access devices. The relay can also be used to route electrical signals from one system to another. Additionally, the HE721A2400 is capable of triggering other relays to take over from one line to another.

Aside from telecommunication applications, the HE721A2400 is also used in industrial applications, such as controlling industrial automations, robotic arms, and other OEM solutions. The reed relay can also be used to activate switches in power distribution systems, to route electricity throughout a factory, and to control mechanical pumps. Additionally, the HE721A2400 has the capability to control solenoid valves, which are used extensively in aerospace and medical applications.

The working principle behind the HE721A2400 reed relay is relatively simple. It consists of two pairs of reeds enclosed within a glass envelope. When an electrical current is applied to the reeds, they become magnetized, causing them to move away from each other. This movement causes the contacts in the relay to close, and when the current is cut off, the contacts open again. The reeds then return to their original position and the connection is broken.

The advantage of using a reed relay over other types of relays is that it has a much lower power requirement. This makes it ideal for applications where low current is required to switch, such as telecommunications and industrial applications. Additionally, the HE721A2400 reed relay has a high switching frequency and excellent contact bounce characteristics, making it suitable for high-speed applications.

The HE721A2400 is an ideal choice for a variety of applications, from telecommunications to factory automation. It is a reliable, low-current relay that is suitable for high-speed applications. Its simple yet efficient working principle allows it to be used in a range of applications with ease and confidence.
