The TQ2-L-5V is a signal relay specifically designed to provide uninterrupted DC switching of up to 2 amps. It is an important component in industrial equipment, consumer electronics, automation and instrumentation, and other applications that require isolation. This article will discuss the TQ2-L-5V’s field of application and explain its working principle.

Applications

This signal relay is great for a range of applications that call for reliable switching of DC current. TQ2-L-5V offers dependable and more importantly, safe operation. It is suitable for applications that need secure isolation between two independent loops. It is also recommended for industrial programmable logic control, distributed control system, and monitoring panel applications.

The TQ2-L-5V relay also makes a great choice when you need to switch massive currents. It is a suitable component in battery chargers, backlight charging, inverters, AC adapters, DC motors, voltage controllers, and other comparable applications. This type of signal relay also excels when it comes to switching signals with longer pulses.

Working Principle

The TQ2-L-5V signal relay is designed to operate by generating sound, shock, and vibration. The basics of its working principle involve harnessing the contact force produced by the relay’s inner vibration when subjected to an AC electric field.

The relay is equipped with an inner ceramic bobbin that has stripes of metal wound around it. A magnetic field is created when the bobbin is subjected to an AC electric field. This magnetic field causes the inner bobbin to vibrate and the actual contact force is generated by the machine’s inner vibration.

The contact force is used to push and hold the contacts together when they cross each other, and to separate them when electricity is supplied. The force is also used to reduce the damage caused by an electric arc.

Conclusion

The TQ2-L-5V signal relay is well suited for various applications that require the reliable switching of DC currents. It can also handle signals with longer pulses. Its working principle involves harnessing the contact force generated by the relay’s inner vibration when subjected to an AC electric field. This results in a signal relay with superior performance and efficiency compared to other models.
