Reed Relays

Introduction

Reed relays are a type of electromagnetic switch used in automation and control engineering. Reed relays are used in a variety of applications including telecommunications, security systems, and industrial automation. They work by coupling the actuation circuit to the relay contacts. This allows for a current to be sent through the contacts, which opens the contacts and allows an electrical connection to be made. Reed relays are more efficient than other types of relays because they don’t require external power and are able to switch quickly.

7302-05-1101 Application Field and Working Principle

The 7302-05-1101 Reed Relay is a single-pole relay designed for use in a variety of applications. This type of relay is typically used in communication systems where reliable, low-power signals are required. The 7302-05-1101 has a low-power rating of DC 10 Watts and an engravable metal housing with a 1” mounting foot. The contact rating is 0.5A with a switching voltage of 300Vmaximum.

The 7302-05-1101 operates on a magnetic-induced electromagnetic field from the core at the base of the relay. A coil is mounted around the core which, when energized, produces an electromagnetic field which carries current through the moving contacts. When the contacts open, an arc is created, which dissipates the current. The relay has a sliding contact arm which contains an adjustable, repeating “hatching” pattern. When an electric current is applied to the hatching pattern, it moves the sliding contact arm, and the contacts open or close depending on the hatching pattern.

Applications for the 7302-05-1101 Reed Relay include radio-frequency communication systems, security systems, HVAC systems, and motor control. It is also used in industrial automation using PLCs or DCS systems and in medical equipment. The 7302-05-1101 is also suitable for applications involving electromechanical relays, contactors, switchgear, and temporary power distribution.

Conclusion

Reed relays, such as the 7302-05-1101 model, are a reliable and efficient way to switch current and are commonly used in a variety of applications. Their low power usage makes them ideal for applications where power consumption needs to be kept to a minimum, and their magnetic-induced design allows for faster switching times than other types of relays. The 7302-05-1101 is suitable for use in radio-frequency communication systems, security systems, HVAC systems, motor control applications, and industrial automation.
