Signal Relays, Up to 2 Amps: EE2-12NUH-L Application Field and Working Principle

The EE2-12NUH-L is an electronic signal relay device manufactured by Panasonic, specifically designed for applications that require a moderate current to be reliably switched by a low-level control signal. Its capabilities make it suitable for a wide variety of uses, from automotive saw switching to industrial-scale strain gauge switching.

A signal relay is a device that can electrically isolate a low-level control signal from a normal power source. The EE2-12NUH-L is a type of signal relay that is rated for current up to 2 amps, making it applicable for most general electrical switching needs. By effectively isolating the low-level control signal from the high-voltage power source, the EE2-12NUH-L can ensure that the control signal remains safe from overvoltage and provides a reliable ways for switching moderate load currents.

The EE2-12NUH-L is commonly used in applications such as automotive saw switching and industrial-scale strain gauge switching. In these types of applications, the signal relay is used to safely switch between several states, such as when the saw is on or off, or when the strain gauge is at a certain level. The signal relay ensures that the low-level control signal remains safe, while allowing for reliable switching between the different states.

The EE2-12NUH-L works on the principle of a split-coil latching relay. This type of circuit uses two oppositely-magnetized coils that are sandwiched between each other. When current is applied to one of the coils, the magnetic force generated creates an electromagnet that attracts and moves the contact arm. This causes the contact arm to switch states depending on the direction of the current, either opening and closing the circuit, or holding the state either open or closed.

The EE2-12NUH-L can be used in various applications and is suitable for applications that require switching currents of up to 2 amps. It is constructed with a plastic housing and contact arm and is available with a variety of terminals and contact arrangements. This makes it suitable for a wide variety of applications, from automotive saw switching to industrial-scale strain gauge switching.

In conclusion, the EE2-12NUH-L is a signal relay device manufactured by Panasonic that is specifically designed for applications that require a moderate current to be reliably switched by a low-level control signal. It is rated for currents up to 2 amps and works on the principle of a split-coil latching relay. The EE2-12NUH-L is suitable for a wide variety of applications, from automotive saw switching to industrial-scale strain gauge switching.
