Signal relays are widely used in electronic systems for the purposes of enabling, disabling and controlling electrical signals. The TQ4-L2-6V is a signal relay manufactured by the TQ series, and it is designed for applications up to 2 Amps.

The TQ4-L2-6V is a snap-acting, hermetically sealed relay that has a built-in diode and comes in a 4-pin package. It has a maximum coil voltage of 6V, a maximum switching voltage of 200V, and a maximum switching current of 2A. Additionally, the TQ4-L2-6V features a three-pole contact arrangement with both an A-coil and a B-coil output.

The TQ4-L2-6V has a variety of applications where it can be used. It is commonly used for telephone and audio-visual equipment, where it provides reliable control of signals on a smaller scale. For example, it can be used to control the direction of a signal or to isolate a signal from the electrical circuit. It can also be used to detect and measure faults on telephone and television cable systems. Additionally, the TQ4-L2-6V is suitable for many applications where switching current and voltage are relatively low, such as in security systems, industrial automation, and the automotive industry.

The working principle of the TQ4-L2-6V, like other relays, is based on the switching of a magnetic field. This is achieved by passing electric current through a coil, which produces a magnetic field. When the coil is energized, the magnetic field will attract a disc-shaped arm, which is the moving contact. This contact is then connected to an electrical contact, and the electrical circuit is then completed. When the coil is de-energized, the moving contact will be released, and the circuit will be broken. This switching action of the TQ4-L2-6V is reliable and repeatable, and it can be triggered by relatively small electrical signals and currents.

In summary, the TQ4-L2-6V is a signal relay designed for use in applications up to 2 Amps. It has a snap-acting switching action that is triggered by small currents and voltages, and it is commonly used in telephone and audio-visual control circuits, security systems, and the automotive industry. The TQ4-L2-6V features a three-pole contact arrangement with both an A-coil and a B-coil output, making it an ideal choice for applications where switching current and voltage are relatively low. Overall, the TQ4-L2-6V is a versatile and reliable signal relay that is suited for a wide range of applications.
