Signal Relays, Up to 2 Amps, TQ2SL-L2-4.5V Application Field and Working Principle

Signal relays, especially small electrical relays, are used to control electric power circuits. Relays are used when it is necessary to control a circuit by a separate low-power signal, or when several circuits must be controlled by one signal. The TQ2SL-L2-4.5V signal relay is one of the most widely used signal relays in the world. The TQ2SL-L2-4.5V signal relay has a two-pole construction with a contact load rating of up to 2 amps. It is available in both traditionally wired and non-traditional flat panel designs. Additionally, it features adjustable coil voltage and a pick-up/drop-out characteristic for low power operation and high reliability. When applied, the TQ2SL-L2-4.5V signal relay allows a low-current control circuit to change the state of the main circuit. When the relay is switched on, the electrical contacts are closed, and the main circuit is energized. When the relay is switched off, the contacts open, and the main circuit is de-energized. The TQ2SL-L2-4.5V signal relay is ideal for applications such as motor control, solenoid and lamp control, consumer electronics and alarm systems. It is also suitable for automotive applications such as power windows, power seats, door locks, and brake control systems. Additionally, it is used in electronic load switching in microwaves, induction cooking, and air-conditioning systems, among many others. The working principle of the TQ2SL-L2-4.5V signal relay is based on electromagnetism. When voltage is applied to the relay’s coil, it creates a magnetic field which then attracts an armature. The armature is connected to the contacts and when it is attracted, it initiates the switch closure action. The TQ2SL-L2-4.5V signal relay uses a bifurcated contact construction, which allows for ultra-high reliability and superior dust and moisture protection. It also has surged current capability, reducing the chance of premature contact wear or failure under high-current conditions. Moreover, the product is UL and CSA certified. To ensure the highest performance, the TQ2SL-L2-4.5V signal relay is designed with a unique cover construction which has been tested to various global standards. This cover construction ensures the highest safety levels and the protection of the coil from dust, moisture, and electromagnetic interference. In conclusion, the TQ2SL-L2-4.5V signal relay is one of the most widely used signal relays in the world. It is extremely reliable and suitable for a range of applications such as motor control, solenoid and lamp control, consumer electronics, and alarm systems. It is also UL and CSA certified and features a unique cover construction for superior dust and moisture protection.
