Reed Relays

Introduction

Reed relays are electrical switches used to open or close circuits using an electromagnet to move a reed contact against a fixed contact. It consists of a fixed armature and a moveable armature surrounded by hermetically sealed glass. Reed relays are mainly used in data communications, contactors, computers, aerospace, automotive and industrial applications.

7104-24-1101 Application Field and Working Principle

The 7104-24-1101 Reed Relay is designed to incorporate high-power carrying capabilities into a standard-sized, hermetically sealed relay. It is ideal for use in high current circuits. The operating voltage of this relay is up to 350 volts, while the contact rating is up to 40 amperes. The 7104-24-1101 reed relay is composed of an enclosed hermetically sealed glass body with an internal, twisted, electro-magnetic coil. The coil has two primary characteristics; its resistance value is determined by the type of reed relay, the wire diameter, and the length of wire that is wrapped around the coil, while the inductance is determined by the number of layers of wire. The 7104-24-1101 reed relay operates according to the following principle: when an electric current is sent through the coil, a magnetic field is generated. This magnetic field attracts the moveable armature of the relay, which contains a reed contact, and which moves towards the fixed armature of the relay, thereby bridging the gap between the two contacts and completing the circuit. When the electric current is removed from the coil, the magnetic field is removed and the moveable armature returns to its resting position, breaking the circuit. The 7104-24-1101 relay is usually used in applications requiring high current switching. It is suitable for use in the aerospace, automotive, computer, contactor and industrial sectors. It is widely used in data communications, power switching, and motor control applications due to its versatile design.

Conclusion

Reed relays are an important type of relay used in a wide variety of applications, especially in data communications and power switching contexts. The 7104-24-1101 relay is a hermetically sealed, high power carrying reed relay designed for use in high current circuits. This relay is used in the aerospace, automotive, computer, contactor and industrial sectors due to its versatile design and operating principle.
