Signal Relays, Up to 2 Amps

The TQ2SL-4.5V relay is one of the signal relay products available in the market today. It is designed to control the ON and OFF operations of a wide range of circuits, including consumer electronics, automotive, industrial and commercial equipment. This model is powerful enough to handle voltage surges of up to 2 Amps, making it suitable for tough applications.The TQ2SL-4.5V, like all signal relays, is typically made up of several components. The most important component for understanding its working principle is the control coil or coil circuit. The control coil works similarly to a magnet, with a specific voltage rate and ampere turnover. When a specific voltage is applied to the control coil, it creates a magnetic field, which attracts the armature contact and completes the circuit. The working principle of the TQ2SL-4.5V is thus based on the interaction between the control coil circuit and the armature contact. The control voltage applied to the coil is usually one-tenth the rated operating voltage. When a control voltage is applied to the coil, it creates an electromagnetic field. This field exerts a force on the armature, pushing it against a spring, or anchor, and completing the circuit. The completion of the circuit is what causes the relay to activate. The TQ2SL-4.5V has many applications, with one of the most common being for automotive power accessories. This signal relay can help control the ON and OFF of electric windows, power door locks, sunroofs, and other accessories. It can also be used in the control systems of industrial and electrical equipment, as well as in commercial lighting and heating systems. To protect the TQ2SL-4.5V relay from excessive voltage, it is usually fitted with overload protection circuits. These circuits help to protect the relay and the connected circuit from excessive current. If the current exceeds the protection level, the relay will not activate. This is important as excessive current can damage the relay and the connected equipment, as well as trigger potential safety issues. The TQ2SL-4.5V is a highly reliable and robust signal relay. It is designed to operate within a temperature range of -40°C ~ +125°C, and can cope with harsh operating environments. With its overload protection circuits, the relay can handle over voltage and current peaks, and still retain its optimal performance. This highly versatile signal relay is ideal for virtually any application requiring precise control, and can be used in both industrial and consumer electronics.
