Signal Relays, Up to 2 Amps

The UA2-12NU signal relay is an ideal device for controlling the flow of signals up to 2 Amps in various applications. It is a small, electrical device that can be used to switch on or off either AC or DC signals. The relay can also be used in separating circuits and transistors so that signal flows are not affected by external components.The UA2-12NU is available in many different form factors. Its dimensions are 1”x1”x1”, and the package includes terminals, a mounting base and a diode. It is also available in PCB (printed circuit board) form. The UA2-12NU signal relay is manufactured using highly localized materials.

Applications of the UA2-12NU

The UA2-12NU can be used in a wide variety of applications that require the management of signals up to 2 Amps. Some of the most common applications of this relay include:

• Security systems and burglar alarms
• Medical devices
• Home appliances
• Industrial machinery and process controls
• Electrical switches and connectors
• Automotive and aviation electronics

Working Principle of the UA2-12NU

The UA2-12NU signal relay is a switch, which uses an electrical power source to switch on and off a signal’s flow. This is achieved by two key components. The coil on the relay produces an electromagnetic force which, in turn, pushes the armature into contact with the main contacts. This completes the circuit and either opens or closes the switch.When the coil is energized, it produces an EMF or EM force, which causes the armature to mechanically move and actuate the contact. This triggers the operation of the UA2-12NU.

Conclusion

The UA2-12NU is a small, highly specialized signal relay, capable of managing signals up to 2 Amps. It can be installed in a variety of form factors and provides efficient signal switching for the applications mentioned above. Its working principle of Electromagnetic Actuation provides very reliable switching of the circuit from both AC and DC signals.
