Reed Relays

Reed relays are electrical switching devices made from two flexible metal strips, typically sealed in a glass envelope, and when electricity is applied to one of the contacts, it causes the contacts to open or close depending on the state of the contact. Reed relays have many applications, including telecommunications, electronic data processing, audio and video applications.The HE721A0550 reed relay is a coaxial relays designed by Teledyne Relays and is used for high frequency switching applications. The HE721A0550 has an operating voltage range of 5 to 50 V DC, and an operating temperature range of -20 to +85°C. It is a single-pole double-throw (SPDT) type relay with a 1/4" quick connect tab for easy installation. The HE721A0550 has a switching capacity of up to 0.5A at 125V DC and a maximum load resistance of 60ohm.The HE721A0550 reed relay has a wide range of applications, from precision switching to high-frequency switching in computer, telecommunications, audio-video, security, automotive and other industries-related applications. The HE721A0550 reed relay is designed for low-power operations and is suitable for applications such as power line control and microprocessor control systems. It can be used to control AC or DC signals, such as switching a variety of applications, from powering up and down of a system to changing the speed of a fan.The working principle of the HE721A0550 reed relay is simple. When power is applied to one of the contacts, the two metal strips bend, thus closing the connection. When the voltage is removed, the strips will return to their original position and open the connection. This allows for very precise control over the switching of the relay.The HE721A0550 reed relay is a reliable and versatile solution for applications that require low-power, high-frequency switching. It is an ideal choice for applications such as automotive, telecommunications, security, audio-video, computer and power line control systems. The HE721A0550 reed relay offers a low switching capacity and a wide operating temperature range, making it an excellent choice for high-performance and high-reliability applications.
