Introduction to Reed Relays and 7143-12-1111

Reed relays are electromechanical switches consisting of an electromagnet, an armature and a closed reed switch. The reed switch is a hermetically sealed, glass-encased, two-contact device made of ferrous materials which are magnetically triggered by an external current passing through the electromagnet. When an electric current is applied, a magnetic field is generated, which causes the armature to move and close the reed switch, and the relay changes its state from open to closed.

The 7143-12-1111 reed relay is a single pole, low voltage/current, latching reed relay. It features excellent insulation resistance and heat resistance, sealed metal cover construction for improved safety and durability, and low power consumption. It is a widely used relay in consumer and manufacturing industries, especially in the automotive, medical and consumer electronic industries, for its compact size, high efficiency and reliable operation.

Application Fields of 7143-12-1111

The 7143-12-1111 reed relay is used in a variety of applications. It is a preferred choice for low-voltage/current circuit applications, such as low voltage/current switching, low voltage/current power control, low voltage/current auxiliary power distribution, low voltage/current power backup, and low voltage/current protection. Additionally, it is also used in a range of industrial, commercial and consumer applications, including automotive, medical and consumer electronic industries.

In the automotive industry, the 7143-12-1111 reed relay is used for controlling electric motor speed, engine temperature control, lighting, and vehicle monitoring. It can also be used in medical devices such as infusion pumps, respirators, defibrillators, and other medical equipment used in hospitals. In the consumer electronics industry, it is used in handheld electronic devices, such as mobile phones and PDAs.

Working Principle of 7143-12-1111

The working principle of the 7143-12-1111 reed relay is based on the magnetic field created when an electric current passes through the relay\'s coil. The magnet inside the relay forms a magnetic field which causes an armature connected to a reed switch to move. This causes the reed switch to close, thus completing the circuit.

When a current is applied to the coil of the relay, it produces a magnetic field, which will make the armature swing and close the reed switch. When the current is removed, the magnetic field will immediately stop, and the armature swings back to its initial position, thus opening the reed switch and thus disconnecting the relay from the circuit. This can be helpful when needing to interlock multiple relays in a cascading fashion for electrical control, allowing for more flexibility in electrical circuit design.

Conclusion

The 7143-12-1111 reed relay is a commonly used relay in multiple industries. It is a single pole, low voltage/current, latching relay that features excellent insulation resistance and heat resistance as well as low power consumption. It is often used for low voltage/current circuit applications such as switching, power control, power backup, and protection. Additionally, the reed relay is widely used in automotive, medical and consumer electronics industries. The working principle of the 7143-12-1111 reed relay is based on the magnetic field created when an electric current passes through the relay\'s coil, which causes an armature to swing and open or close the reed switch.
