Signal relays are electrical switches used to control communications and signal flow in electronic circuits. They are classified by their switching characteristics and amperage ratings. The UB2-4.5NU-L is a signal relay rated up to 2 amps, making it suitable for low current and low power applications.

The UB2-4.5NU-L is a latching type relay, meaning that it requires no continuous power to maintain the switch state. This makes it ideal for applications in which power consumption is a concern, since it does not consume electricity when not actively switching.

The UB2-4.5NU-L features dual coil contacts and is rated up to two amps and 250VAC/VDC. It uses a miniature signal relay construction technique, making it well suited for tight spaces and modern equipment designs. The UB2-4.5NU-L is also designed to minimize noise and interference, making it ideal for sensitive or audio applications.

The relay can easily be mounted to a PCB, and is designed with a wide range of fingers for prototyping and PCB support. Additional features include a built-in surcharge protection diode, as well as fine soldering lugs for easy connections. This design is also UL recognized and meets ISO9001 quality standards.

The UB2-4.5NU-L works by using two coils, one for closing the switch and one for opening it. By applying a voltage to the appropriate coil, the relay will activate the contacts, allowing current to flow. This type of signal relay is commonly used to switch between two circuits, or to switch multiple circuits at once. Its two-amp rating means it can handle low-current and low-power applications.

The UB2-4.5NU-L is suitable for a wide range of applications, from industrial systems to consumer electronics. Its electric-dynamic performance is reliable and efficient, making it ideal for controlling electronic signals in demanding environments. It is often used to control motors, fans, lights, and other low-voltage applications.

In summary, the UB2-4.5NU-L is a signal relay rated up to 2 amps and 250VAC/VDC. It is a latching relay design, meaning it requires no continuous power to maintain the switch state. It also features a miniature signal relay construction, with dual coil contacts and built-in protection diode. The UB2-4.5NU-L is suitable for a wide range of applications, from industrial systems to consumer electronics. It is ideal for controlling low-voltage signals in demanding environments.
