Power relays are specialized electromechanical switches that can carry a large amount of current and set off electric currents. They can come in many different shapes, sizes, and functions. The HJ4-L-T-AC12V is one of the many available power relays capable of handling up to 2 amps of current. In this article, we will discuss its application field and working principle.

Application Field

The HJ4-L-T-AC12V is mainly used in a variety of electronic applications. It is suitable for industrial control systems, electric motors, household appliances, power transformers, contactors, circuit breaker/relay panels, and many other circuits. It can be used to control motor currents, switch on/off AC circuits, and provide overload protection.

Working Principle

The HJ4-L-T-AC12V power relay may work differently in each application but the general operation is the same. The relay includes an electromagnetic coil, consisting of a wire wound around a metal core. When a voltage is applied to the coil, the metal core becomes magnetized and the relay is said to be energized. This action causes a pair of contact points to open or close, allowing or stopping current from passing through the circuit. It can also be used to provide a circuit with overload protection, usually shutting power off if the current exceeds the safe limit.

The HJ4-L-T-AC12V is a reliable, long-lasting power relay. Its robustness makes it suitable for high power applications. Its contact points will close or open even under high load, and the contacts themselves are made out of high quality materials to minimize wear and increase durability. Furthermore, its coil is protected to minimize damage from short circuits or over-voltage.

Conclusion

The HJ4-L-T-AC12V is a versatile power relay that can be used in a variety of electronic applications. It features a robust design, long-lasting contact points, and overload protection. We hope this article has given you a better understanding of this powerful and reliable component.
