Signal Relays, Up to 2 Amps

The TQ2H-L2-12V is a type of signal relay that is commonly used in a wide range of electronics, due to its ability to switch currents up to 2 Amps reliably and with minimal effort.

Signal relays are a type of electronic component that act as an electrical switch, connecting or disconnecting one or more lines of a voltage or current. The most common type of relay is the electromechanical relay, which is based on a coil of wire wound around an iron core and movable contact armature. Electrical current flowing through the coil creates a magnetic field which causes the armature to move, thus opening or closing the contacts.

Although electromechanical signal relays consume a small amount of power when they are activated, they have several benefits over other types of relays. Firstly, they are not as susceptible to noise interference as solid-state relays, and secondly, they can handle much higher current levels due to their larger moving parts. This is particularly useful for applications that require switching of currents up to 2 Amps.

The TQ2H-L2-12V is an example of a signal relay that is suited to these tasks. It is designed to handle loads up to 2 Amps and can be used to switch currents up to 60 Volts. It features two normally open (NO) contacts and one normally closed (NC) contact, allowing the user to switch both positive and negative polarity signals. The relay is also protected against over-temperatures, meaning that it will shut itself off if its temperature reaches a critical level. This helps protect against potential dysfunction in circuits.

The TQ2H-L2-12V signal relay can be used in a variety of applications, such as automotive electronics, computer peripheral interfaces, and audio/video systems. It is usually triggered by a voltage or current applied to the coil, although it can also be triggered using a small transistor gate. Its versatility, combined with its reliable performance and built-in protection, make the TQ2H-L2-12V an ideal choice for many applications.
